好了 别弄太多 一点就行
威尔 欢迎来到我们村 这是我们的荣幸
I've got a confession to make.
I've never swum in a lake.
Never climbed a mountain.
I was in a cave once.
And I've never slept in a tent.
But I'm beginning to think that I might be missing something.
So, I hooked up with some modern-day explorers
and I asked them to take me to the ends of the Earth.
And they said, "Oh, we can go further than that."
So, I'm 51, and I haven't done any climbing whatsoever.
And I've always had this secret fantasy
that I wanted to summit Everest.
I think we're the same age, almost.
Yeah, I'm... September 25th.
Yeah, no, I'm the 23rd.
- Really? - Yeah.
I have two days more of wisdom... in my life.
What are my chances? Or... is that like a young man's game?
No, no, I think you could totally do it.
I climbed Everest in 2001.
I've gotten to climb some beautiful mountains around the world.
Been to the tallest mountain on every continent, so...
So, Jackson, what's the name of the volcano?
- Yasur. - Yasur.
- Yasur. - Yasur, what does that mean?
Someone bigger than us.
It's like God to us. So, it's bigger.
So, we could be driving up there right now to a volcano that's about to erupt.
So, we're actually gonna see boiling lava.
- Yeah. Yeah. - Okay.
- So, we are entering the ash fields? - Yes.
- So what? Vegetation is ending and... - Yup.
Right, we're getting into the ash?
And I can hear it hitting the windshield.
This is scary.
I almost guarantee you're gonna survive.
Face-to-face with Mount Yasur.
One of the most active volcanoes on Earth.
But there's another reason why Erik thinks
I'll be more curious than scared.
For one, the loudest sound ever recorded was made by a volcano.
But the loud sound that this volcano makes is completely silent.
Yeah, I know. I don't understand it either.
- Did you just hear it? - What?
-有什么声音吗 我错过了 -是的
- Oh, no, there was a sound? Oh, damn it. - Yeah.
It echoed all the way across up there.
Erik is clearly listening. But to what?
- I'm officially sweating. - Yeah.
You gotta be kidding me.
- Right? - Yeah.
Is the edge okay, you think?
You tell me.
Like looking into the gates of Hell.
You can hear the sound like compressing, like hitting the walls...
-是的 -在下面回响 就像这样
- Yeah. - down there. Like that!
And it's kinda dark right now, right, so it's...
- Yeah. - It's really lit up.
You just kind of forget that Erik is completely blind.
I mean, this a man who climbed Everest.
Who just hiked this volcano without a single stumble.
Who could even tell when the landscape changed on the drive over.
You just kind of forget until he asks you to describe it to him.
And it's what colors, orange?
It's like orange fireworks shooting out of the ground.
Do you have any emotion around... not being able to see it?
when I went blind, there was a time where you sort of regret
and stuff like that, but...
eventually, I think I learned that you gotta sort of
say goodbye to that sighted life.
And kinda take on a new life and, you know,
part of you dies, a part of you is reborn.
Close your eyes. What do you hear?
So, it's really similar to the ocean. It's like waves crashing.
-潮起又潮落... -是的 没错
- Comes in and goes out and... - Yeah. Totally.
On Yasur, there's such a spectrum of sound.
There's this sound that you can consciously hear.
But I'm beginning to feel this deeper sound.
You can't quite hear it.
But you kind of just know it's happening beneath you.
Erik and I aren't the only ones looking for a hidden world of sound.
There's a new breed of explorers going to the ends of the Earth
in an attempt to discover the hidden worlds
that sit beyond our senses.
And some of them are taking it way, way further than I would ever dare.
Diva Amon studies the loudest animal on the planet up close.
But getting that near requires some pretty special skills.
When you want to listen to the sounds of the ocean,
you have to free dive.
Without any oxygen tanks, it's so much quieter.
And you don't exhale loads of bubbles,
which can scare the animals off.
But you can only stay under for as long as you can hold one breath.
You don't normally think of clicks as noisy.
These ones, they're louder than a chainsaw.
That's what makes sperm whales so interesting.
It's their way of talking.
And each click contains whole paragraphs of information.
The clicks are so loud
that they can carry across hundreds of miles of ocean.
They can also use their clicks to echolocate...
or to scan unknown objects.
The noise is so powerful...
you can feel it pulse right through you.
天啊 太惊人了 我真的感觉到了
Oh, my God, it was amazing! I actually felt that!
Could you feel them?
You don't just pick up sound with these.
You can also pick it up here.
But if I'm going to experience sound through my body,
then I'm gonna have to get my body closer to the sound.
And that means stepping off the rim of this volcano and going in.
-你好 -你好吗 哥们
- Hello. - What's up, man?
-不错 很高兴见到你 -我也是
- I'm good. Real nice to meet you. - All right, pleasure, man.
欢迎来到亚苏尔山 你好 埃里克
Welcome to Yasur. Hey, Erik.
- How're you doing? - Awesome.
- How are you? - Cool.
I think you're my first volcanologist.
All right, cool.
So... have you ever been to an active volcano before?
I have not.
Later on today, we're gonna be descending into the crater
and then I'm gonna have you help me install some sensors.
Thought maybe I would draw this... an illustration.
Using a stick in the ash.
Mind using this pole, so that I can feel?
Yeah, love to do that...
All right, now I'll be able to feel you.
Great, so, right...
Well, this is a big crater,
and I'm drawing an arc of the crater rim,
which is about a 300-meter or a 1,000-foot diameter crater.
And what we'll be doing later is descending
via three independent rope systems down into the crater,
but not all the way down.
So that we can get down to an ideal location to install this apparatus.
In fact, there's a bench right down here, a flat area,
that I think is ideal for the installation of the sensors.
So what... what are the potential dangers?
The thing I am most careful about is making sure none of this ash
- gets blown into your eyes. - Got it.
- It's little pieces of glass, right? - Glass.
Could really hurt your eyes.
So, goggles, gas mask always at the ready.
So, you're... you're a volcanologist by trade.
So you feel comfortable going in there,
and you'd take your students or anything in there, right?
Yeah, I would take you in there.
- I didn't answer that question. - I know, yeah, right.
It sounds like the beginning of a really bad joke.
It's like, okay, okay.
A rapper, a blind man, and a volcanologist
rappel down into a volcano.
But that's what we're gonna do. Help Jeff record the mystery sounds
this volcano is making.
I saw you a couple of times,
and you'll, like, snap your fingers or make a sound.
是的 你打响指 我就敲敲我的手杖
Yeah, snap your fingers, I'll tap my cane,
or sometimes, some people do a click.
It's like... really like, the sharper the better.
-那你是在... 回声定位 -是的
- And you're... you're echolocating? - Yeah.
- And that works? - Yeah.
I went totally blind about a week before my freshman year in high school.
I'd been diagnosed with this incredibly rare eye disease
called "juvenile retinoschisis" as a young boy.
And throughout elementary school and middle school,
I just watched the world shrink away.
I struggled for a while,
thinking without sight I would be stuck on the sidelines of things.
But the beauty of hearing is
that you can hear things that no eye could see.
You can hear behind you, just as well as in front of you.
So, yeah, there's all kinds of things that I can see with my ears
that you may not be able to see with your eyes.
These rocks, I'm assuming,
were fired out of the volcano and landed here.
Yeah. This is a beautiful example of a spatter bomb.
- Jeez. - And, you know why it's flat, right?
-几乎是平的 -因为... 它可能有延展性
- Flattish. - Oh, because... So it was probably malleable.
And then it hit and squashed down?
I'm guessing that's what's shooting above us right now?
Yeah, so, this is not a good place to be right now,
when there's elevated activity.
That seemed like a big one.
Those spatter bombs are huge.
- How high did that one go? - Above our heads.
The very rare potential for catastrophic harm
is a direct ballistic that goes from the vents straight shot up.
- Yeah. - And if you're leaning over the edge...
俯身... 明白 是的
Leaning over... Got it. Yeah, yeah, yeah.
- that would be potentially really bad. - Absolutely.
You don't have any warning when it's a straight shot.
We were told that when you hear the sound of the volcano
to immediately turn and take your eyes to the spatter bombs
because they go up as lava but they come down as massive rocks.
And I'm thinking... Well, what about Erik?
With a sighted person,
their visual cortex lights up when they're seeing motion.
For me, my visual cortex lights up when I'm hearing motion.
I create a picture in my mind. So I still see,
but it's all based on sound.
There is a way that we can all see sound.
But it's not for the fainthearted.
Both planets became molten on impact.
Debris thrown out into space...
Every February, the townspeople of San Juan de la Vega
take part in what has to be one of the world's most bizarre festivals.
It might seem crazy dangerous,
and it is.
These violent explosions demonstrate something crucial about sound.
Something that explains why you can feel it
even if you can't hear it.
It can move stuff.
Sound doesn't just travel through the air.
It causes movement of the air.
These invisible forces can even burst an eardrum.
Because sound is movement.
That is what Erik is feeling on our volcano.
And down in the crater, it's just possible that I'll feel it too.
And we need the helmet because the volcano spits rocks and stuff,
and the rocks go up in the air, and then they come down.
And they hit you in your head.
As if this helmet's gonna do something...
...for one of these big-ass rocks.
You know, you might ask why we're going inside.
The answer is that we're getting the highest quality signals possible
if we go in the crater as opposed to up on the rim here.
For real, that's hot.
Now that we're actually about to go down there,
I can't stop thinking, a few days ago without warning,
a volcano erupted in New Zealand killing 22 people.
Now, does that volcano erupting mean anything about this one?
Any last words?
Yeah, this is my action hero pose.
-埃里克 准备好了吗 -好了
- Erik, you ready? - Yes, I'm in.
-威尔 你呢 -准备好了
- Will, ready? - Yes, sir.
I may have lost my mind.
这儿有热气 毒气 玻璃 灰尘
There's crazy heat, toxic gas, glass, ash.
Hell, even the smoke is out to get you.
All right, on rappel.
-好的 我们慢慢下去 -来吧
- All right, on rappel, guys. - Let's do it.
You've never done this before, huh?
Not for real.
This is for real.
Hey, that's coming up over the rim.
Let's do the science quick.
Oh, my God!
Oh, that's immense.
Oh, my God! All right, that's the biggest one yet.
- You feel that? - Hell, yeah.
Guys, let's get this array out as quickly as possible.
If we hear a big explosion, eyes towards the crater...
and let's walk that out as carefully as you can.
Will, did you feel that through your body?
-是的 难以想象 -是啊
- Yeah, that's crazy. - Yeah.
It's like a...
I felt the vibration before the sound.
Right, it's like a shock wave
- that hits you before you hear it. - A shock wave before you... Yeah.
Will, are you starting to understand what I'm feeling?
I get it.
The last one that went,
my eardrum wobbled, but I didn't hear a sound.
- But I felt the pressure of the wobble. - Oh, yeah.
Yeah, I feel that wobble like all the time. I don't know.
- Do you feel that wobble right now? - Yeah. Yeah, I feel it right now.
Erik, I can't hear that wobble that you're discussing right now.
I'm just not sensitive to it.
- But I believe you. - Yeah.
Because this is what the device is telling us.
- Right. - And when we turn it up...
...this is generating audible tones from that wobble
that you're perceiving.
If you could hear this, it would be like you were next to a jackhammer.
- Right, right. - And you would not be able to have a conversation.
- What you're hearing is infrasound. - Right.
Talk about low. Infrasound is bass and then some.
So, when you feel it, you better pay attention.
What did you say? Oh, we need to leave?
Okay, I heard you. I heard you.
Infrasound just told you that?
Infrasound said we need to get the hell out of here.
Rock! Rock! Rock! Rock!
You all right, Erik?
Decoding the infrasound could help predict
when volcanoes like Yasur will erupt.
But there might be other messages coming from down there.
Sounds that could tell us something crucial about our world.
Out on thin ice, these skaters only stay safe
by listening really carefully.
Extremely rarely, ice can behave a bit like the Earth's crust,
amplifying even the slightest noise
into something weird and unexpected.
And just like the volcano might be signaling it's about to explode,
the sounds from a frozen lake can warn us how weak the ice is.
Higher sounds mean thinner ice.
It doesn't take much to make the sound,
just the tiniest bit of pressure can do it.
Sound travels faster and much further through solid surfaces.
So, now you know why in old cowboy movies,
folks put their ear to the ground when they wanted to hear distant riders.
That's the idea that one group of explorers
are taking a little bit further.
But first, they need to find somewhere with no sound at all.
And it ain't easy to get to.
We are going to try to get to a place
where we get the absolute silence for human beings.
Okay, cool. I'm excited.
All right. Down we go.
- Get this. - Thank you so much.
Do you want some more? I can fill.
Sure, thank you.
The phenomenon that we experience here is that
our brain doesn't want us to experience the silence.
But if you pay attention,
if we... if we keep silence, then we still hear
the water dropping.
- Okay. - Just... Just try it.
This is probably the last sound that we're gonna hear now.
Until we get to the place
where we hope to find the virtual silence.
Okay. So, we keep going now?
-去更深的地方 -没错 继续深入
- Just deeper. All right. - Yes. Yeah. Going deeper.
It looks like we... we found it.
Hey, guys, let's try to be quiet for a minute
to see it's really something that we've perceived, the...
these quests of the silence,
and then we can maybe deploy the technology.
There's nothing. There's nothing.
I think that's the first time in my life I've ever heard...
- Nothing. - Nothing.
- Yeah. - Yeah.
Yeah, nice and pretty amazing.
-感觉很沉重 -是的 完全没错
- It's heavy. - It's heavy, yeah, totally.
It's like... It's a heavy sensation.
Yeah. So, this instrument what they will do...
is to record whatever we cannot hear now.
If you want to hear something really quiet,
quieter than your breathing, quieter than your heart beating,
then you either have to stop those things
or get the hell out of the way.
That way, you might just have a chance of hearing something
no one's ever heard before.
Sounds from deep within the mountains.
It's actually thought to be the sound
of the moon's gravity dragging the mountains.
The moon pulls on the sea to create tides.
It turns out, it does the same to the land.
And it's not just the mountains that are moving.
Imagine you could peel away the sounds of New York City, one by one.
Eventually, if you get quiet enough,
you just might find those same deep, primal rhythms
recorded in the Dolomites.
Because the moon moves cities too.
New York rises and falls up to 14 inches
twice a day, every day.
An invisible wave of concrete and steel.
They're called Earth tides.
Coming down from the volcano,
Jackson takes us to his village to celebrate.
And I realize I am listening to everything differently.
The layers of sound.
I could feel my hearing turn up.
I was tuned into a... whole world of sound
that even as a musician had been hidden from me.
I feel pretty proud that I was able to give Will
a little glimpse into my experience.
To not just be wowed by all the visual things in the world,
but to actually be able to hear subtleties
and beautiful things and violent things.
Sight is just a sliver of reality.
And so, in a way,
maybe I'm helping him to really experience the full spectrum of living.
He's singing up there.
This dance symbolizes the villagers' relationship
with the sounds of the volcano,
like harmonizing with the primal forces of nature.
So, all of these dances and everything are about the volcano?
没错 描述了岩浆在火山里融化 沸腾...
Yes. Exactly how the lava is melting inside, like, boiling...
So that's why... Sometimes you can hear it like this.
The dance mirrors the sounds of the volcano.
The claps are the explosions.
The stomps are infrasound.
The whole thing celebrates the sounds
that pass through their bodies every single day.
要我加入吗 好的 来吧
You want me to go? All right, let's go.
Everybody up. Let's get it.
Yo, that's crazy.
It's like the ground is a bass drum.
跳得好 就是这样 埃里克
There you go, man. That's it, Erik.
Everything on Earth is making a sound.
Each and every thing.
It's a song we might not always be able to hear,
but it's a song we can learn to feel.
Tune in to the Earth.
Pick up its hidden rhythm.
And learn to dance along.
I've changed how I listen, how to really listen,
but that's just the beginning.
There are more hidden worlds to explore.
Alien worlds where color exists in total darkness.
Wow, look at that.
Where strange things start to happen
when millions of animals come together.
Where stillness doesn't exist
because every single thing is moving.
These are the hidden worlds that drive our planet.
The new frontiers that challenge everything we thought we knew.
When I was a kid,
my grandmother used to say all the best things in life
lived on the other side of fear.
I sure hope Gigi was right.
Will, welcome aboard.
-迪瓦 你好吗 -我很好
- Diva! How are you? How are you? - I'm good!
You're just in time.
- That is fantastic. - Yeah, this is the Nadir.
And she's gonna be our vessel into the depths.
- "The Nadir"? - Nadir.
What do you think?
That's straight off a movie set. That's science fiction.
We're going down to the bottom of the ocean in this thing.
I'm gonna be honest, I'm a little nervous,
'cause that submersible is just a...
it's just a little... it's a little ass... it's a little ass thing,
and there's gonna be three people in there.
This is tricky...
because in the real world, I'm frightened of water.
Watch your head.
-这还有面墙 别撞到头了 -好的
- You have another wall. Watch your head. - Absolutely.
So, this is a biggie.
Three thousand feet down in a plastic bubble.
- Up the steps. - Up the steps.
Face the front of the sub, sit here.
- Yeah. - You're aimin' for the center console.
It's near the lamp. And pop your feet in.
威尔 就是这儿 滑下来
Right here, Will. Slide on in. Yeah!
- And then I'll get you to stand on there. - Yeah.
And then you're gonna sit on that one.
There you go.
Squeeze on in.
There's a water bottle.
- The water bottle. - And some more snacks.
-我把零食放下来啦 -这挺... 舒服的
- I'll put your snacks down. - This is... snug.
So, she's like a gazelle.
Or should it be a sardine, just squeezing into the can.
- She knows what's she's doing. - Done this a bit.
All right, I'm gonna give you a quick safety brief.
Both of you have a built-in breathing system.
If you need to, it's just a standard scuba rig.
-如果我让... 是的 我让你们... -像这样
- If I let... Yeah, if I tell you to... - So, we go like that?
just pop it in your mouth, then breathe normally.
And if something happens to me, there's a button under here.
- Okay. - All right?
- Yellow. - Yellow button.
- The yellow button. - Right there.
-按下按钮 然后... -天哪
- Press the tool, and... - Oh, Jesus.
我已经把它搞坏了 救命 抱歉
I've broken it already. Mayday, sorry.
Press the tool, and let them know,
-"X光 X光 X光" -好的
- "X-ray, X-ray, X-ray." - Okay.
Okay, any questions?
Have you ever crashed one of these things into something?
-有的 经常的事 -经常的事 好吧
- Oh, yeah. All the time. Oh, yeah. - All the time. Yeah, great.
Are you actually nervous?
-你真的紧张吗 -只有一点 我会没事的
- Are you actually nervous? - Just a little bit. It'll be fine, though.
请回复 这是纳迪尔 我们准备好下水了
Echo, Nadir, we are ready for the water.
Ready for water.
See y'all later... I hope.
Little bit of tingle.
Here you go.
请回复 这是舰桥 可以发射了 可以发射了
Echo, bridge, you are clear to launch. Clear to launch.
收到 准备发射 所有位置已解除
Roger, clear to launch. Break. All positions are lifting now.
And lift off.
Here we go.
I definitely just got nervous.
If your feet get wet, please tell me.
That would be terrible! Man.
And we are detached.
Not emotionally. Emotionally, I'm still very attached.
控制台 控制台 这是纳迪尔
Control, control, Nadir.
通风口安全 生命维持系统运行 完毕
Vent secure, life support running. Over.
Nadir, control. Roger.
Surpassing five-zero meters. Descending.
Some of my earliest memories actually revolve around the ocean.
We'd be out on the boat, and I would desperately,
absolutely desperately want to know what was down there.
But I'm not sure Will feels that way.
The circle of light above us is shrinking.
One thousand meters, 3,300 feet.
A place so deep, not even light gets down there.
But what exists in total darkness?
Back on the surface, other members of our team
are asking the same question.
There are a lot of people who are afraid of the dark.
And I'm one of them.
I got bitten and dragged by an American crocodile in the dark,
and it's kinda made me a little bit wary.
But not wary enough to stop her canoeing at night
in a glass-bottom boat.
Part of being an explorer is overcoming your fears,
and when you do that...
that's when you get to see the magic.
We have life.
This water is full of tiny creatures.
Disturb them, and they burst into sudden light.
You row through them, and you create a light storm.
We think it might be a defense.
Like turning on a security light to reveal intruders.
Oh, look at that.
Any movement in the water picks up a glow, even these fish.
Here, sharky, sharky.
Oh, yeah! That is a nurse shark.
That's gorgeous. Look at his tailbeats.
This world is far from dark.
Its constellations, its stars swirling underneath your fingers
and underneath your paddles.
It's the most beautiful thing I've ever seen.
A magical world that you'd never experience
if you stuck to the safety of the day.
So, we're losing light as we go down.
And with that, the colors.
Exactly, so, white light is made of lots of colors.
And as it hits the water, different colors
get absorbed before others.
That's how my grandmother taught me the rainbow. ROYGBIV.
红色 橙色 黄色
So, you know, red, orange, yellow,
绿色 蓝色 靛蓝色 紫色 所以
green, blue, indigo, violet. Got it. So,
-红色先被吸收 然后是橙色 黄色... -没错
- red goes, orange goes, yellow goes... - Exactly.
So, it's like blue is the last to go,
and that's why everything looks blue in the ocean.
Check your shirt out.
We were picking wardrobe,
and they kept demanding the red shirt.
- They kept demanding... - What did you think it was for?
不知道 我想着"拜托 我想当探险家"
I didn't know, I was like, "I wanna be an explorer, man."
We're gonna just be in a blue world soon.
- A dark world. - Dark world.
We've only just started,
and already the light from the surface is fading.
But before the dark, there's twilight.
A world we think of as having very little color.
As night falls, the world as we know it totally disappears.
It disintegrates around you.
Our eyes struggle to make out our surroundings.
I can hear it.
I can hear it getting louder. Yeah.
- Garuga... - Garuga is coming.
有时 在满月期间 当天空晴朗时...
Sometimes, during a full moon, when the skies are clear...
a ghostly arc of light appears in the mist.
It's a moonbow.
It's nearly impossible to see.
It's like this thin, grey line in the air
that's stretching out over the entire gorge.
But with the right camera and the right lens,
you can see the line for what it really is.
It's a rainbow, but it's created by the moonlight.
This is perfect.
The white light is bouncing off water droplets in the air,
just like it does after a rainstorm.
But here's the thing. Moonlight isn't actually strong enough
to activate our color vision.
So, the moonbow remains hidden in plain sight.
It's a world of color that is just completely hidden in darkness.
The ocean has twilight, too.
Go down below 200 meters,
and you're getting beyond the reach of sunlight.
And the twilight zone is full of things no one has ever seen before.
控制台 控制台 这是纳迪尔
Control, control, Nadir.
深度为700米 下潜中 完毕
Depth, 700 meters, descending. Over.
Did you hear that clunk then?
- Yes, I did. - That's the sphere telling us
- we're getting deep. - Yeah.
- Okay, shall we do some exploring? - All right.
This feels just like Star Wars.
I keep expecting to see the Death Star.
Do you ever get used to this?
Can you believe that more people have been into space
than the bottom of the ocean?
I've only been down a handful of times
because these trips are just so rare.
Less than one percent of the deep ocean has been explored.
And even though you're traveling deeper into the darkness,
you actually start to see more.
Well, that just came out of nowhere.
That is a whole cliff.
- That's amazing. - Isn't it?
Maybe it is the Death Star.
- We have no idea how tall this is. - Right.
- How far this goes, right? - Yes, yes. Absolutely.
And before now, no one has been here.
So, I could literally be one of the first people to ever see this?
等下 按探险家的规则 我不是能给它命名
Wait, aren't the explorer rules that I get to name it?
- Yeah. - The Fresh Peak.
What is that?
Enypniastes, enypniastes, enypniastes.
Go back, go back, go back.
It's weird as hell.
Okay, this is a type of sea cucumber.
Formal name, Enypniastes eximia.
But it has a bunch of nicknames.
My personal favorite is the headless chicken monster.
The headless chicken. Wow! Look at that.
It really does look like a roast chicken...
that ate a giant Philly pretzel.
They're just one of my favorite things to see.
That is beautiful.
You can see that it's red,
probably the most common color of animals in the deep sea.
Why do you think that is?
That's a good question. I don't know...
It would probably be for concealment, right?
-没错 可以隐匿起来 -正是如此
- Yeah. They can hide. Yes, yes. - Exactly!
-因为这儿没有红光 -是的 它们...
- 'Cause there's no red light. - There's no red... They...
- You can't see them. - You can't see 'em.
So, it's like they're wearing an invisibility cloak.
They act like my T-shirt, right? That's my invisibility cloak.
Most of the creatures down here can't even see red.
Yeah, I guess, they don't need to in a blue world.
So, is everything down here red?
- There's a jellyfish right here. - Yeah?
- Right in front of us. - There.
能看见它在动 它们都是... 彩虹色的
You'll see it's moving. They'll all... Where the rainbow is.
That's amazing. Use your phone?
It's like a five-color light bulb in the middle of it.
- That jelly actually has no color. - What do you mean?
It only looks colorful because we are shining a light on it.
What do you... what's that mean?
That rainbow is never seen down here.
- Because we have brought that white light. - Right. Right. Right.
And so, that is actually not a real thing.
-海底没有生物能看见 -是的 它们都看不见
- Like, no animal down here sees that. - Right. No animal sees it like that.
Even though I can see this rainbow,
the creatures down here can't.
And I can only see it because we brought the right sort of light.
That approach can work in all sorts of surprising ways.
And it turns out, you don't have to go that far
to find hidden colors in the dark...
just as long as you have the right sort of light.
I heard something.
They're right down here.
I think they know we're here.
- Why don't we go dark? - Okay.
Can you try the magic light?
Yeah, there's movement right there.
It's like it's disco paint.
It is. It's amazing, isn't it?
Only a handful of people in the world have ever seen this.
It's amazing, how a little trick like this with UV light
can just reveal a whole new world. Who knew?
And that's the thing.
No one knew. This is brand-new science.
As we speak, scientists are wandering randomly around
with UV flashlights trying to see what other animals
might have this hidden power.
When you first saw this, you must've thought you were,
like, hallucinating or something.
My sanity was questioned, yes.
Not the first time.
Who knew that animals were putting on a secret light show
in our own backyards
using colors that we can't see?
What we're looking for doesn't need special lights.
But what is left to see when all light is gone?
This is where we're probably beginning to go into the midnight zone.
To get to the midnight zone, you need to go deep.
Close to the limits of what this sub can handle.
So, as the sub is going deeper,
the most unnerving thing is the noises it makes.
This, like, horrible creaking.
And that's the battle between the sub and the ocean.
And it's completely terrifying if you stop for a second
and think about the fact that the only thing protecting you
is about six inches of plastic.
Toby, I'm gonna start slowing down now.
Nadir, control, roger.
Here we go.
We're at the bottom.
That's about three inches from the seabed.
即将着陆 休斯顿太空中心 开启着陆灯
Coming in to land, Houston. Contact light.
I always wanted to say that. I just never really had a reason.
I love this part, when you see the seafloor
just loom out of the depths at you.
It's so surreal when you think about it.
We're here, a kilometer below the ocean surface.
Personally, for you, what is your life's goal,
your hope for what you're doing?
'Cause I'm from a developing country...
we, as a nation,
can't afford to explore the majority of our area.
Like, 90-something-percent of Trinidad's area is deep ocean.
And we have no idea what's there because we don't have the expertise.
I'm the only one.
So, a big part of my work is trying to change that.
I've been on, like, 16 expeditions now,
and there is hardly ever anyone that looks like me,
whether it's a woman, a person of color,
or a person from a developing country.
- And I want that to change. - Absolutely.
So, that's a big part of why I do what I do.
Got it. That's cool.
Inside the sub at 3,300 feet.
We down here.
We down here, y'all. We down here.
Let's just say, I got really, really inspired,
and I just wanted to take a walk.
Probably last about half a second.
- And we would die in the process. - Yeah.
I probably won't do that then.
I always think, "What a great way to go.
"What a great story."
A great story is one that you get to tell.
- Somebody else... - Right, yeah.
别人来讲这个故事 就是"是啊 我也在场"
If somebody else has to tell it, "Yeah, man, I was there that day,"
it's like a less great story.
If the pressure is that extreme,
you've gotta wonder, "What kinda creature could live down here?"
Because even back on the surface, explorers are finding
some crazy, strange lifeforms hiding in the dark.
What is an astronaut doing in a cave...
300 meters below the earth's surface in utter darkness?
Going into a cave is very, very similar to actually going to space.
You lose colors, and then you lose the concept of colors.
If you look around, most creatures that live down here
are white or transparent.
They have adapted to living in a cave,
so they got rid of colors, they got rid of eyes, even, totally.
These creatures, they don't even see.
An olm looks like the kind of creature an astronaut might find.
That weird, fleshy skin.
They call olms the human fish.
An alien that only needs to eat every ten years.
Which is just as well
because they move too slowly to catch much.
A species that has been hidden away in the dark
for over 20 million years.
If they found that thing
in a cave just a few hundred feet down,
what the hell are we gonna find at 3,000 feet below the sea?
Control. Control. Nadir.
Depth, 1,000 meters. Over.
What was that?
There's only one way to find out.
Yes. And there's a trick we play.
Now, we'll see what's out there.
So, shut your eyes.
Okay. One, two, three.
Try it again. Let's turn on the flash.
Okay, eyes shut.
One, two, three. Lights on.
Lights off. Eyes open.
Oh, my God!
Oh, my God.
You have got to be kidding me. Look at that.
It's like Close Encounters.
So, Diva, what is it?
Well, this is what we're here to see.
A hidden world you can only see in total darkness.
不 我知道 但从科学上说 这到底是什么
No, no, I know. But, like, actually, scientifically, what is it?
It's bioluminescence, Will.
It's a chemical reaction using oxygen in the water to create light.
But just look at it.
So, they're making their own light.
Exactly. And they use that light to communicate.
They are communicating with us, right?
-好像在喊"母神 母神" -像"阿凡达"里那样
- Like, "Mother! Mother!" - It's like Avatar. Yeah.
或者 "哥们 把该死的灯从我脸上移开"
Or, "Yo, man, get them damn lights out my face."
Or they're like, "Do I wanna mate with you?"
I know, yeah.
There's like this whole language I never even knew existed.
Of all the space on the planet in which animals can live...
over 99 percent of it is in the oceans.
And within that huge space, nearly 80 percent of animals
use bioluminescence in some way.
And so, actually,
bioluminescence may be one of the most common forms
of communication on the planet.
That is mind-blowing.
How did I not know that this was in the world?
Back to the surface.
Control. Control. Nadir.
回到400米深处 上浮中 完毕
Passing 400 meters, ascending. Over.
This is right out of a romantic comedy.
I'm so putting this in a movie. I am so putting this in a movie.
I was just wondering who you'd put in as me.
- You'll be, like, Matt Damon. - Oh, yeah. Matt Damon.
- You know, somebody like that. - Yeah.
Back to the sunshine.
We set out to find a hidden world in the depths.
And I discovered that
there's more light in the darkness than I ever imagined.
From the deep, dark ocean...
all the way to the sunlit surface...
we live in a world of color.
Yes, I like this part!
Will, you did it.
- The sun just bursts back into your life. - That was great.
That was definitely great.
My grandmother used to say,
"God places the best things in life on the other side of fear."
Well, He also puts the brightest things in life on the other side of darkness.
So much so,
that I only really began to see... when I descended...
into the dark.
Another hidden world awaits us.
I fulfill a childhood dream,
to witness one of the greatest migrations on Earth,
and discover that in the world of swarms,
even unintelligent animals can become super smart.
Let's hope we don't see what the lions do at night.
Let's hope we see lions before they see us.
Hey, Rem. Can you cut the lights?
Well, this is... We got a pair of night vision goggles,
and if you look out there, and tell me what you see.
I need night vision goggles to get the night vision goggles from you.
Well, I can see they're wildebeest.
Well, that's a start.
Can you tell their shape? Like the shape of the group?
I can't tell, really...
They're like layered up, so I can't really tell.
- Kind of stacked up? - Yeah.
I don't know. Let's see what...
I've got another toy I wanted to show you.
I wonder if a lion could see in this kind of darkness. I dunno.
Well, that's... We don't need to find out that.
是的 我会... 我会和角马一起丧命
No, no, I just die... I'd die with the wildebeest.
- You can follow me? - I can't see.
-我领着你 没事的 -好的 慢慢走
- Yeah, I got you, we're good. - All right. Hold on.
My whole life, I've wanted to see wildebeest.
I just didn't think it would be in the dark with lions everywhere.
But George has a different way of looking at everything.
Well, we're looking at these guys, it's interesting, they're moving out.
Oh, wow, yeah.
But I don't think they can see anything at night.
So they're falling in like that, but they're not falling in based on sight?
They're walking differently.
Almost kind of like a loose defensive formation.
They're coming together and working as a group.
- They're clearly following each other. - That's right.
But if they don't see well, and they're not making any noise,
how do they know where the others are?
Around thirty years ago, I picked up a National Geographic Magazine
and saw this.
That image, one and a half million wildebeests on the plains of Africa,
has stayed with me ever since.
The most dramatic migration on Earth.
And finally, I'm here to see it.
Hey, Will. Come up and take a look.
That's a lot of wildebeest, man.
Seeing them up close, finally. Man, they're kind of funny-looking.
Wildebeest are not the most elegant animal.
Or the most intelligent.
George is straight-up clowning wildebeest.
But, hey, if they don't get by on their looks or their brains,
how do they survive out here in the wild?
Well, that's what George wants me to see.
The front runners chow down on the grass ahead of the herd,
so they all have to keep constantly moving.
And so do we.
So, George, what got you to... to Africa?
I got kind of bored, I was a... kind of bored college student,
and I decided to get the hell out, and I wanted...
I went to Africa, I came hitchhiking here.
I bought a one-way ticket to London...
and I hitchhiked down to Congo.
And I found it was really fascinating and there was so much more to learn.
- Yeah. - And I still feel that way.
Once you get into dangerous things, you just keep on learning more and more.
What kind of image are you hoping to capture?
Well, I'm trying to capture the key moment in the migration
when the... when the wildebeest cross the river.
How often do you capture exactly what you're looking for?
That's kind of a depressing question.
I've been photographing wildlife for over forty years.
As a photographer, you try to capture these incisive moments in an animal,
where they reveal the true nature of their species.
而最宏大 最壮观的 就是角马渡河
And the greatest, the biggie of all, is the crossing of the wildebeest.
雷姆 根据你的经验 这种情况有多罕见
In your experience, Rem, how rare is it?
How easy will it be for you to catch a crossing?
You have a big chance of seeing a wildebeest, of course.
-是的 -但看见角马渡河 千载难逢
- Yeah. - But it's seeing crossing, that's very rare.
But I think you can consider it a great failure
if you don't show me a... a crossing.
You know, wildebeest don't care...
wildebeest don't care who you are, or how long you've been waiting.
-我知道 是的 -它们真的不在乎
- I know, right. - They don't really care.
Hey, you guys, do you know what?
The wildebeest haven't seen Men in Black, I guess.
In fairness, they've got more pressing things to think about.
But somehow, between them, they manage to survive a 300-mile trek
past hungry lions, hyenas, and cheetahs.
What's their secret?
Perhaps the answer lies in a completely different creature
over 3,000 miles away from here.
But what can the world's largest honeybee
tell us about wildebeest?
Have you seen bees like this before?
I've never seen anything like this before.
Your problem's gonna be how to get in there and be able to then...
- sort yourself out to be able to shoot. - Not... Okay, yeah.
- So I'm not spinning in space. - Yeah.
Maybe we'll try and climb up from the bottom
and then, from there, try to get in position.
Well, I guess we should go try it.
There can be as many as 100,000 bees on a single hive.
And they can be pretty damn hostile.
If they decide to swarm when you're at the top of a rope,
there's literally nothing you can do.
Aldo, I'm in position!
Can you get quite close? Over.
I can touch it.
I can touch the outer part with my hand and the inner part with my foot.
I'm gonna try to trigger 'em.
There's a sort of invisible barrier around a hive.
It's about 20 inches away.
Cross that line, and something astonishing happens.
It's a kind of defense strategy.
If the bees spot a predator breaking through that perimeter,
they flip their bodies, starting this massive chain reaction.
It's like they're somehow all connected, and not just by touch,
but like they're thinking as a single unit.
On its own, each bee doesn't amount to much.
But as a swarm, they can create something big enough
or confusing enough...
to deter almost any attacker.
So the bees have their shimmer trick to throw off predators.
But the wildebeest don't have that.
I don't think.
So how do they defend themselves?
雷姆 那儿有只狮子 能停一下吗
Rem, there's a lion over there. Can we stop for a minute?
Look out on the left.
Oh, yeah, I see her. I see her.
She's gone again. I lost her.
Let's try changing our perspective.
I've always loved getting up and looking at things in a new way.
When I was a kid, I was a real tree climber,
much to my mother's chagrin.
I loved climbing up to the tallest branches
to get a view over my back yard.
And now my back yard's become a lot bigger.
Can you see her?
Like a flash mob.
If it were humans down there, that would be chaos.
I'd be tripping up and bangin' off this dude,
and runnin' into that guy over there.
But the herd didn't miss a beat.
Just kept on keepin' on.
It looks difficult.
But it turns out, you just have to follow three simple rules.
Rules that apply to all sorts of animals that swarm.
Rule number one, don't get too far away from your neighbor.
Rule number two,
don't get too close to your neighbor either.
第三条 如果你的同伴转弯 你也转弯
Rule number three, if your neighbor turns, you turn.
And that's enough to turn thousands of individuals
into something beautiful and complex.
Starlings can fly at 40 miles an hour.
So to keep together in formation,
they need the reactions of racing drivers.
Especially as the other "cars" aren't just in front or behind,
they're above and below.
It's hard to get how special that is,
until you see it mapped out.
A hundred thousand birds racing around a constantly changing track
without a single crash.
That's the way the wildebeest roll too,
with simple rules and not overthinking it.
They're not as fast or as pretty,
but as they search for fresh grass,
the wildebeest are just as coordinated.
Things get more complicated when they reach the Mara River.
Keeping an eye on the guy next to you isn't much use,
when you're facing strong currents...
and giant crocs.
It's the single most dangerous part of the whole 300-mile round trip.
Wait, we can get out here?
It's safe. Yeah, get out.
I'm gonna let you get out first.
"That looks good, you go first?"
What are we looking at?
Basically, this is the main barrier that the animals have to go over
to get up to the big grasslands of the Mara,
where the really good vegetation is for them at this time of year.
So, what... what are all of these marks?
Those are the crossing points, so we mark it.
Like, it's along the river,
so whenever they cross, we just put the mark,
so we know like, crossing number two, number three, number four.
They seem to have a few favorite places.
But if they cross at regular spots,
why is it so hard to catch a crossing?
- There's no way to know which one they're going to choose. - Ah, okay.
Conglomeration of thousands of animals,
and they all might have crossed at a different place the year before,
so they've gotta have like a group decision,
like a swarm decision, About which way to go.
We can either hold and wait in one spot, or we can get fidgety and patrol.
If there was a crossing happening, we can go there,
but by the time we get there, it might be over,
so it's like, do you...
It's hard to know whether you chase after crossings
- or do you wait for a crossing to come to you. - Got it.
So, how long will it take for me to get comfortable
just letting a fly be on my face without having to swat it?
'Cause you got two flies on your face and you're just relaxed.
- I'm like, man. - I just get tired of swatting at them.
- Bush... Really bush man. - Oh, man...
All right, so are we waiting or are we chasing?
My instinct is to find a really good place.
We got a lot of animals over there.
And if we're in wait, they'll come to us.
- All right. - Yeah.
So we sort of look where they're moving to, right?
是的 它们在往河边跑 这儿有一大群
Yeah, they're coming to the river. And see, the herd is down here.
- They're moving faster, yeah. - Trying to run there...
Are these guys about to cross?
I can't believe how lucky we're about to get.
Never underestimate the power of beginner's luck.
I mean, George has been trying to get this shot for years,
and I'm here two minutes and it's all happening.
I'm just saying.
去吧 乔治 这是你的重大时刻
Go, George. This is your big moment.
He's going on his own.
Oh, I can't watch this.
Why did they let him go alone?
Looks like there's a fourth swarm rule.
Don't go where there's crocs.
If I saw one of my boys get wacked by a crocodile,
I'd have second thoughts about crossing that river too.
Looks like the momentum now is moving away from this point.
Where it was moving toward this point before,
now it feels like it's kind of gently drifting away.
Clearly, one brave dude jumping into the water
is not enough to make them all start crossing.
So, what will it take?
To best explain that, we need to go underwater.
They are truly amazing.
The first time I ever saw them,
certainly something that you'll never forget.
Flashlight fish are weird.
They make their cheeks light up like,
"I'm here, follow me!"
But just like that poor wildebeest,
one fish signaling isn't enough to make the others follow.
Neither is two or three.
But if enough of them flash at the same time,
in the same direction...
...they all go.
It's not about one animal taking the lead.
It's about enough of them doing it.
Then the swarm behavior kicks in strong.
So this is a numbers game.
The place where the wildebeest are most likely to cross
is the place where the biggest numbers are gathering.
But how do you find that?
Well, with a plane with the doors off,
and a crazy co-pilot.
Here we go.
Come forward, you can see it better.
That's a huge line.
That's definitely the most we've ever seen.
That's crazy. It does look like ants, like how you see ants move.
-是的 像行军蚁 -是的
- Yeah, like army ants. - Army ants, yeah.
There's a few thousand there at least. A convoy.
That one's even bigger.
You can definitely tell where this bunch is heading.
Straight to the river.
We gotta get there before they start crossing.
Roger that. Let's get down there.
Let the games begin.
Look at that line, those lines.
Have we found our crossing point, Rem?
So, I think we better hold here.
'Cause if we drive close, may scare them, they may run away from the river.
So our presence would potentially keep them from crossing?
True, yeah. So, we'd better continue to wait.
So, now we just wait for someone to call "action"?
Welcome to wildlife photography. It's a lot of waiting.
Eh, it's not different than acting either.
You just kinda sit around and wait.
♪ 在丛林里 在茂密的丛林里 狮子今晚睡着了 ♪
♪ In the jungle, the mighty jungle, the lion sleeps tonight ♪
I'm out of breath.
♪ 在村庄旁 在宁静的村庄旁 ♪

I'm a real explorer if I have a slouch hat?
-没错 -很好 所以...
- Yeah, exactly. - All right, so that... so...
so it's like... it's like, that's the vibe?
It looks good. You go first.
I'm not gonna go first. You go first.
-不 你先下去 -不 你先去
- No, you go first. - No, you go, you go.
-不 你先 -我就跟在你身后
- No, you go, you go. - I'm right behind you.
Just go ahead. I mean, you're already standing there, just go ahead.
是的 我挺你 哥们
Yeah, I got your back, man.
The single brain is saying, "I don't want to get eaten."
But the swarm mind is saying,
"There's grass over there. Let's go."
It's a pressure cooker.
Maybe what they really need is one last push.
There are tiny dots of slime mold almost everywhere.
Most of the time, slime mold just sits around,
eating bacteria and making more slime mold.
But when these single-celled organisms run out of food,
something weird happens.
Waves of restless energy ripple through the swarm.
They join themselves together into a new creature.
Many cells become one body.
And then when the pressure finally gets too much, they move.
There's sacrifice involved.
The long, thin stems are created by cells dying.
But they give the others a chance to survive
by being carried away to pastures new
when something brushes against them.
Individually, these guys are literally brainless,
but together, they're smart.
And wildebeest? They're a bit like slime mold.
Loads of individuals somehow having to make a joint decision.
Thousands of brains slowly crunching the data.
"Danger in front...
"food running out behind."
Waves of nervous energy building...
that finally pushes them to the edge.
And an answer.
They're going. Going.
- They're gone. They're gone. - They're going.
Look at that.
- All right, you got the... - They're crossing.
- Get the bino... - Thank you, thank you.
That looks crazy.
I've had more than half my life to get ready for this.
But nothing prepares you for the dust,
the noise, the sheer scale of it.
Hey, that... Once you commit...
No turning back.
All right, 30 years. That was on my bucket list for like 30 years.
We just got it, the migration of the wildebeest, the crossing of the river.
We have done what we have come to done.
Thousands and thousands of individual organisms
surviving by joining together.
The swarm drives them and protects them.
Not everyone can make it.
But most of them do.
Look at them go. It's like they're tied together.
You can, like... You can feel the connection.
So it looks like, even from...
What could be a quarter mile away, that they know.
Like these all the way back here,
can sense what's happening up here.
For almost 30 years, I've had an image in my mind.
The plains of Africa dense with millions of wildebeest.
But in the end, I saw something I wasn't expecting.
It's not millions of animals at all.
It's just one.
Like George said, shift your perspective,
switch your lens,
and you'll see the swarm everywhere.
Makes you wonder, do they even know they're in a swarm?
Come to think of it, do we?
Damn. Now, that's a question.
Next, I'm on the trail of a deadly predator.
- There he is. - You got one.
Following my nose to solve a desert island mystery.
That is gorgeous.
And discover that smell is not what it seems.
This smells terrible.
That's the whole point.
Will, try to put a little muscle into it.
- All right. - Give it a good shake.
Yeah, I remember this from Jaws.
Tiger sharks usually spend their lives alone,
wandering the oceans.
But once a year, they mass together near the Great Barrier Reef,
all heading in one single direction.
You got one.
Come to us, baby.
Quick, quick, quick.
Pull it right in. Pull it quick, quick. Pull it right in.
Pull up, pull up. Steady.
Don't let him fight!
Don't let him fight! Don't let go!
I've got you. Pulling him tight.
-威尔 拉紧绳子 -好的
- Okay, Will. Hang on to that rope. - Yup.
These Australian researchers want to track one of the sharks
to find out where they're going.
-威尔 你抓住了吗 -我抓住另一头了
- You got her there, Will? - I'm on the other side.
Yup. Hold the tail high.
That was good, you're secure.
Watch those teeth.
Watch that, it's still around your leg.
Come on, get that!
- Ready? - Yup.
This one's a...
He's okay, right? He'll be all right?
Especially if you start calling her "she." She'll be much better.
"She?" All right.
Gotta watch the gender pronouns, sorry.
They don't use hooks, so she's not harmed.
How big is it?
- Yup. Got it. - What is it?
- Three point four. - Which'll be about twelve feet.
- All right. - Three-four!
Well, we're trying to learn what the sharks are doing here...
'cause we need to know where they go, what their home ranges are,
and then we can follow it via satellite.
We know from the tiding that these sharks are coming
from thousands of miles away.
And we know that sharks follow smells underwater.
So, we know that they're here because they smell something.
In nature, smell can mean the difference between life and death,
particularly, when you're dealing with sharks.
The question is where are they going and why?
- Your first tiger shark. - Yeah, well...
- I'm not gonna need to do that two times. - No?
Tiger sharks are so mean that they eat other sharks.
So, getting into the water to photograph one?
That's next level.
-准备好了吗 你需要什么 -我的相机
- You're good? What do you need? - My camera.
Nothing reminds you of how small and fragile humans are
than being in the water with a tiger shark.
It's not for the faint of heart.
It takes diving into the deep end
and really immersing yourself in their world
to begin to understand these creatures.
Being a wildlife photographer, what I'm trying to do
is paint a picture of our planet.
I try to show what's beautiful and special about nature,
the majesty of our planet
and how it supports all living things, including humans.
Cristina's coming up.
- My camera? - Uh. Yup.
Did you get the shots you wanted?
- I did. - Okay.
I did. I got a great shot of the shark and a shot of you.
Did my face looks too scared?
-没有 你看着很棒 -是吗 那我看上去勇敢吗
- No, you looked good. - I looked good. Did I look strong?
Okay. All right.
The tagged shark goes straight back on track...
like it's locked on course.
Something powerful is attracting them.
There might be a clue in a smell that takes me right back to being a kid.
A smell I bet you know too.
Freshly cut grass.
When grass is cut, it releases a scent
that floats straight to the front of your brain...
going to the exact spot where memories and emotions are made.
That's why smells can be so vivid...
And cut grass?
That's the smell of summer.
When a caterpillar takes a bite of grass,
it releases that same scent.
And once again...
...it has an instant effect.
But now, it's not the smell of summer.
It's the smell of lunch.
Smell is the only sense with no filter.
It's hardwired straight to the brain.
It's just that some of us are better at smelling than others.
Sharks have a sense of smell that's hundreds of times more potent
and accurate than that of humans.
Such an enormous part of their brain is dedicated to smelling,
to finding their way through the vast expanse of the ocean.
The shark with the tracker is on the move.
And so are we.
I don't remember anyone in Jaws saying,
"We're gonna need a smaller boat."
Sharks are coming from all over the place,
and they're all honing in on this particular little spot of land
in the middle of nowhere...
So what's happening on the island?
That's the next thing that we need to figure out.
What makes this speck of sand in the middle of the ocean so special,
such a mecca for these creatures to be here?
Is that a turtle?
- Yes, wow. - There it is, there it is.
So, they're taking a breath and going down?
A sea turtle can hold its breath under water for up to seven hours.
So, when you see the same turtle popping its head up
over, and over, and over again...
you know, they clearly are not just breathing,
they're smelling for something, they're sniffing.
Turtles are one of the few animals that can smell both in water and air.
That's why they're popping their noses out.
And whatever it is that they're sniffing,
it seems to be sending them the same way as the sharks.
There's one. There's two.
- Yeah. - One there.
- Just look at them. Wow. - Oh, that's fantastic.
They're all over this place.
- I see more and more and more. - Yeah.
That is gorgeous.
- There's a lot of turtles out there. - A lot of turtles.
Can a shark eat a turtle?
Because, I mean, this looks like a turtle buffet.
You need incredible teeth to munch through that shell.
Tiger sharks are one of the only creatures on the planet
capable of eating an adult green sea turtle.
But the turtles aren't sweating these sharks one bit.
And the sharks are swimming right on past.
It seems like the turtles and the sharks are being drawn to this island.
Raine Island is sacred ground.
If you wanna go ashore, you first have to get permission
from the guardians of the island.
- Hello! - Ma'am.
-你好吗 -很好 谢谢
- How are you? - Yeah, good, thanks.
- Cristina. - Hello, hello.
- Hi. - Yeah. Welcome.
- Will. I'm good. - Yeah. Johnson.
- Johnson. - I'd like to welcome you to our island.
And then there's a ritual to help get rid
of any scents from elsewhere.
Before we allow you, usually you put odor
both on your shoulders and on your head.
Yeah. This is to protect you.
- This is like your smell you're giving me? - Yes.
- Oh, how cool is that. - Yes, so...
I need all the protection I can get, so... Yeah.
You know, we're very grateful and very honored for your hospitality.
- Yes. - Thank you so much.
I can't ever remember being in a place
where smell is so important
for humans and animals.
But what signal is it sending out?
One explorer might have a unique insight.
右转 保持一条线 完美
And right turn. Hold that line. Perfect.
I could do that all day.
Because Erik can't see,
he relies on smell much more than the rest of us.
The wilderness can be such a hostile place.
And I always, as a blind person, thought,
"Could I flourish in that environment?"
See, I'm getting a whiff of salmon.
Where there are salmon, there are bears, so heads up.
Holy cow. He's looking right at us.
Oh, he knows we're here.
What should we do?
不要出声 保持低调 这是它们的地盘
We should be very quiet. Shrink down. This is their neighborhood.
Let 'em do their thing.
When I lost my sight, I started paying attention
to my other senses.
I started recognizing smells that I hadn't noticed before.
I've learned to smell the rain before the drops come.
Or the smell of snow when it's baked by the sun.
Or often, I can recognize trees and plants by their unique scents.
The scent of salmon in the air is so clear to me.
It's a pretty intense smell.
This is how I'm able not just to function
but to really thrive in this environment.
Erik can smell the salmon in the water.
But the salmon are smelling something even more extraordinary.
Thousands of rivers pour into the Pacific Ocean.
Somehow the salmon find their way up the right one to the place they were born.
And if you thought the sharks were good at smelling,
these guys are even better.
They can pick up a couple of drops of scent
in one billion drops of water.
You can definitely tell that we're in the rainforest now, huh?
The musty smell isn't really the trees, it's more the fungi.
When we think of fungus, we think of a single mushroom.
But that's just the fruit of something much bigger.
It's like a giant spider web weaving between the tree roots.
The strands connect the forest to such an extent
树木能相互传递水 营养物质 甚至是信息
that the trees can pass water, nutrients, even messages between each other.
Together, they join huge areas of forest into one single system.
Scientists call it the wood wide web.
So when it rains,
it's not just the smell of the riverbank that's flowing into the stream,
it's the smell of that wood wide web.
A unique cocktail that stays in the salmon's memory.
And guides them hundreds of miles home.
The salmon aren't picking up the smell of their home river,
but the smell of their home riverbank.
But there's no trees on Raine Island.
So, what do the turtles and sharks smell?
we need to get amphibious.
Though, with sharks about, I'm staying near the surface.
You know, even though it looks like one piece of coral...
each branch is actually made of thousands of tiny creatures...
with its own mouth and tentacles.
But in every creature lives an even tinier algae...
and each of those algae release minute bubbles of aromatic gas.
If you look close enough, you can actually see it.
It's this gas that gives off a unique-smelling fingerprint.
But it is that smell that tells the turtles
that they're approaching land because the coral reef
can only grow in shallow waters.
what is for us the smell of the ocean,
for turtles is the smell of land.
You got it.
When I was a kid, we'd sometimes drive to Atlantic City.
It was exciting to get that first whiff of the sea
and know we were nearly there,
'cause you knew you'd be able to get out of that damn car soon.
That's the incredible thing about smell.
One hint of that scent and I'm remembering my childhood vacations.
But for these turtles,
that same smell seems to be about finding their way home.
There's over one thousand miles of shore here.
We're on the Great Barrier Reef,
the longest stretch of coral anywhere on the planet.
The smell it gives off might get you into the right city...
...but it's a different smell that's gonna get you to the right street.
The only other thing Raine Island is famous for is birds.
And, oh, boy, do they stink.
- Very distinct smell, no? - Yeah, that's a very distinct smell.
That bird smell is a tricky one because it's a cocktail.
It's a concoction of dead fish and poo, and that sea smell,
and it's fresh, and it's also been sitting there for months.
I mean it's... it's hard to describe,
but it's pretty unforgettable.
So all of this back here is the original guano?
- Yes. - So this is...
tens of thousands of years of birds...
What's the... what's the scientific word for pooping?
-是... -好吧 所以...
- It's... - Okay. All right, so...
- Evacuating. - Evac...
It just... makes me feel very, very unscience-y.
That smell makes me want to evacuate this island.
But it might be that nasty stink that's bringing thousands of animals in...
So, the turtles smell land by picking up the gases released
by the coral.
And then they hone in on this particular island
because of the smell of the bird...
But why are they coming here?
Well, there's another underwater animal that can give us a clue.
Just like Raine Island, the coral reefs off Indonesia
are home to a secret gathering.
But not turtles.
On one night in spring,
Palolo worms suddenly start to emerge from the reef.
And as they do, they release a scent.
A fragrance they were born to follow.
Because smell in the natural world doesn't always mean food.
Sometimes, it means sex.
That scent is enough to trigger the worms to release their eggs.
A mass spawning that only happens once a year.
That's what the turtles are up to too.
Coming together to lay their eggs.
No, there's not a single male turtle on this beach.
They're all girls.
Oh, look at this.
That's a turtle egg shell.
So, this here is an egg that didn't hatch. You can tell...
...because it's got all the yolk in.
Because it's leathery.
-它是多孔的 所以... -是的
- It's porous, so... - Yeah.
...the baby egg... the baby hatchling inside can actually smell
even while it's in the nest,
and it starts picking up the scent of the island where she was born.
The turtles are born here and they lay their eggs here.
But they don't live here.
In fact, they rarely come ashore at all.
For many, it's the first time they've been on land for years.
And, like an astronaut experiencing gravity again,
they suddenly feel their true weight.
All 350 pounds of it.
They struggle up the beach until they're far enough away
from the tide line to dig a nest.
But it's hot.
More than a 100 degrees.
They need to lay their eggs and get back off the beach
before they get baked in the sun.
They have to rush.
And when you rush, one slip...
can have deadly consequences.
She slipped off these rocks here during the night
when she was up trying to lay, so we need to turn her on her side
um, and get righted up. Otherwise, if she stays like this,
she's gonna die during the day with the heat of the sun.
- And can we help? - Yeah, we'd love a hand.
- Let's do it. - Let's dig in and help flip her.
Okay, so we go under.
Yeah. And be careful...
...from the flipper, otherwise you're gonna get slapped.
小心被扇 懂了 我一直不擅长这点
Avoid being slapped. Got it. Never been good at that.
So good. So good.
- Be careful. - Yeah.
准备好 一 二 三 翻
Ready. One, two, three, go.
That thing is strong.
Yeah, that's why you watch the flipper.
-所以才会如此让人感动 -这种形象 懂了
- That's why you were so moved. - That figures. Okay, yeah.
Her arm is as strong as mine.
It's like there's almost a... like a baseball bat
in the... in the middle of it.
- Seriously? - Like that's how strong it feels.
Without our help, this turtle mom would almost certainly have fried to death
before the day was out.
As many as 2000 die that way every single year.
But not this one.
Not this mom.
She's gonna be okay.
That was beautiful.
Wow, she still looks strong too.
Off she goes. Look at that.
Not every story has a happy ending.
That is a horrendous smell.
- This one didn't make it. - Yeah.
-太残忍了 -是啊 它几乎快成功了
- Yeah, that's rough. - I know. She almost did it.
And you think it's just exhaustion?
She probably got trapped up here, got too hot.
It's over 100 degrees on this beach.
This is one mother who braved everything to lay her eggs,
but she never made it back to the water.
Smells like she's been here a while too.
The good news is that in nature,
- nothing is wasted. - Right.
And that's the answer.
That rotting flesh is what the sharks have come for.
They don't want to take on a live turtle.
Those flippers, for one thing.
But they don't have to.
There are plenty of dead ones to eat instead.
Dozens of mothers who came here to lay their eggs,
but died before they could get back to the sea.
All the sharks have to do is wait in the shallows
for the tide to rise.
The smell that draws the sharks here is the smell of death.
The smell of sacrifice.
Despite the dangers, any mother that survives
will be back following the scent of the island,
risking their lives once again.
That's the funny thing about smell.
It means different things to different creatures.
Life and birth brings the turtles.
Where we smell bird poop, they smell home.
Decay is bringing the sharks.
Where we smell death... they smell dinner.
We pick up those same smells.
It's just that we don't truly understand them.
What triggers a nostalgic memory for us might mean life or death
in the animal world.
The smell of cut grass is really a cry for help.
The smell of forest rain is really the smell of fungus.
And the smell of sea is actually the smell of shore.
You know what's even crazier?
They can remember that exact smell for decades
because they don't come back here until their breeding age,
and that could be thirty years or older.
They remember this place from a smell they smelled thirty years ago?
Do you remember how anything smelled thirty years ago?
I don't... No.
Sunday morning breakfast and the smell of bacon frying.
That smell was spectacular.
And I remember my father who was a... a mechanic,
so he always worked with...
...oils and he had, like, a 20-year-old leather key pouch.
The combination of oil and dirt ground into that leather,
I actually used to like the smell.
What would possess you to smell...
I never... Yes, I remember that.
More than any other sense,
smell is intertwined with our memory and our emotions.
It's an ancient instinct that's just as powerful today.
It's a universal language that links each and every living thing.
加油 小家伙 你可以的
Come on, little one. You can make it.
Good job, young fella.
But its meaning is personal to you and you alone.
More hidden worlds lie ahead.
In the oldest desert on Earth...
I unlock the secret forces...
driving our planet,
好了 三二一 开拍
This is your first time driving in the dunes?
I've been on dunes before. Nothing like this, ever.
- We're still in low, right? - I hope.
注意 威尔 别开太快了
All right, Will, not too fast.
"Pay attention", is basically what you're saying.
All of that freewheeling I was doing, better cut that stuff out.
Think it's up there that it gets crazier.
You only learn through experience.
Don't want to learn too much today.
All right, this... this is a serious one.
This is ridiculous.
Look out, ooh!
- You ready? - I'm ready when you are.
Oh, my God.
It's a steep one.
I got you, I got you.
This is a story about speed.
Oh, my God, Will.
Not how quick I'm shredding these dunes.
A different sort of speed.
A hidden world where things go so fast or so slow...
we don't even know they're happening.
You got your real, like, Zen explorer thing happening right now.
There's, like, nothing happening here.
There's stuff happening here.
You gotta be patient.
So here's the deal.
I'm taking Will across the oldest desert in the world.
And at each pit stop, I'm gonna use state-of-the-art technology
to try to reveal how much of the world he's actually missing.
'Cause often, nature just whizzes by too fast or creeps along too slowly
for us to even notice.
It all sounds pretty far-fetched.
But apparently, this hidden world of speed is everywhere.
Even 80 feet underwater.
测试 一 二 三
Comm check, one, two, three.
There are a lot of anemones.
At first glance, it looks like just hundreds of tiny anemones,
anchored to the rocks.
But film them patiently...
...then speed it up...
...and this miniature world comes to life.
Because anemones are actually animals.
And they do everything you'd expect animals to do.
They breed by splitting themselves in two.
And even more surprising than that...
using a weird sort of gallop.
Seems like down in Fraggle Rock, anemones have to travel to survive.
Just because those dudes look slower than a parked car,
doesn't mean they ain't moving.
Same goes for creatures that move fast as lightning.
That's what Albert and I are after next.
But to capture them,
you better have a cameraman who's quick on the draw.
The second it hits, you have to be, like, on a hair trigger.
- Hair trigger. - And you have to get it
exactly at the moment that you see it, almost predict it.
Almost predict... I have to, like, lean into it?
So it's like the Force, I have to use the Force to push this
and it's gonna record the last two seconds.
It's like recording the past. The camera records the past.
- It's rolling all the time. - It's rolling all the time,
and then when I hit, it'll record the last two seconds?
Yeah. Just because it's rolling so fast...
All right. I'm just trying to understand,
'cause I don't want to mess up the thing you got.
We're using an incredibly powerful slow motion camera
to try and capture one of the fastest muscle movements in biology.
But success is gonna be dependent on Will's reflexes.
- You ready? - Yeah.
你好了吗 威尔 别搞砸了
You got it? Don't screw this up, Will.
Albert, be still.
- I gotta adjust the camera. - Why are you moving?
- 'Cause he's moving. He's moving. - But just be still.
He sees it. He sees it.
There we go. Okay. Ready.
Remember, get it exactly at the right moment.
Damn, that's a crunchy bug.
How are your slow reactions?
My reactions are great.
- Let's see. - My reactions are so good,
I might be before the chameleon.
I had to put it on the maximum delay.
I have no idea whether I got it or not.
But there is no way I'm telling Albert that.
No, I'm pretty sure I did.
So we slowed...
everything down by 40 times with this camera.
Let's see how quick you needed to be to get food around here.
Oh, you got lucky!
Right, let's zoom in.
I'm just noticing how that acceleration builds...
and then, whoosh! Like, you just don't see any of that in real time.
That tongue goes from zero to 60 in just a few hundredths of a second.
That's nearly a hundred times faster than any supercar.
Which is why we just see a blur.
That blur is happening at a speed faster than our brains can actually
- see and process the data. - Yeah. Yeah.
The bigger you are, the faster life seems to be.
The smaller, the slower.
That lizard's tongue is one of the fastest movements
in the entire animal kingdom.
But there are some creatures that have figured out a way
to use speeds way beyond what their bodies are capable of.
Each fall, billions of herring migrate into these fjords.
And they're followed by a fearsome predator.
问题在于 虎鲸有6米长 行动缓慢
Problem is, orca are 20-foot-long and slow.
Herring are one foot long and fast.
So, the big whales have come up with an ingenious solution.
Something far too fast to see.
But I just might be able to hear.
That was it!
That's the sound of an orca
creating a shock wave by slapping its tail.
That pulse can travel through the water
at more than a thousand miles an hour.
And it stuns the herring, knocking them out cold...
...so the orca can just scoop them up.
Speed isn't just about the animals though.
The water itself is working in ways we can't see.
And even in a desert, Albert's found a way to show me how.
Now, that is something I was not expecting.
Look at that!
That's one of the most crocodile-infested rivers in Africa.
They say there's three people a week
who get bit by a crocodile on this river.
Let's not add to that.
And the thing is,
to see what I want to see, I have to get the perfect camera angle.
Which means that Will and I have to get to the other side of that river.
So is there a bridge or something?
- I got a little drone. - All right.
Maybe I can fly a line out to the other side,
around one of those big trees,
and we can get across onto the other side
and see if we can see more of the falls. Do you wanna to do that?
Well, I hope you can do that, 'cause I have a hard time
getting my remote to put the right stuff on the TV I want.
So, if you can fly a drone with a line, I'm with you.
That should probably do it.
- Yeah. Are you ready? - Yeah.
- Watch out for the rotors. - Yeah.
Okay, I'm gonna go.
The idea is to fly the light line around the tree on the other side.
And then we'll use that line to pull a heavy climbing rope across.
That's some MacGyver vibes you got going. Coming down.
- Good job. - Love that.
Now we'll tie the line around this,
pull it around. I'll go across.
Hopefully, I won't fall.
And then pull you across.
'Cause there's really, like, no room for error here.
You got me nervous.
Looks good? Anything dangling?
- Ready? - See you on the other side.
I am not gonna lie.
I sometimes forget about Albert's leg,
he just moves so well.
'Cause, of course, his prosthetic leg is as high-tech
as everything else about him.
- There you go. - Made it.
- You got me? - I got you.
Little further. Keep going.
Oh, that's a man-tester.
-天呐 -你开心吗 我们做到了
- Jeez. - You glad we did it?
Oh, yeah. You're always happy you did it afterwards.
In a movie, my stuntman would've did that.
No stuntman here.
No stuntman here.
Truth be told, Albert doesn't need a stuntman.
My man here just takes it all in his stride.
And more power to him.
'Cause you'd have thought losing a leg would've stopped him in his tracks.
It's incredible when you can look back at a single moment
and realize just how important it was.
I was riding along with a friend in a vehicle...
and then in an instant, everything begins to slow down,
all reality seemed to shift.
I lost my leg in that car accident.
But technology has helped me be able to define my own limitations.
You know, strangely, I don't actually feel like
I've lost anything, I actually feel like I've gained.
It transformed who I am.
It gave me insights into a reality that I wouldn't have seen otherwise.
Let's build the camera rig right here.
You got a lot of high-tech gear.
Well, we're trying to capture some pretty extreme speeds.
Let's not forget what we're up to here. We're trying to see the invisible.
- How's the image? - It's gorgeous.
Great, ready when you are.
Close up and slowed down...
you see the waterfall for what it really is.
of tiny explosions.
Watch even closer, and you see that each droplet is constantly changing shape.
The biggest ones turn into parachutes and then blow apart.
Okay, now let's change speed
and look at the whole waterfall, but in time-lapse.
Wow, that's beautiful. It's totally different.
Just look at those ravines!
All of those tiny explosions have completely smoothed out.
When you look at it like that...
it almost is obvious that the water is sawing the rocks away.
Right? When you look at it like that.
It's like, "Oh, yeah. Obviously, that's cutting the rock."
At this speed,
we are literally seeing how the face of the Earth changes.
It's a completely different experience of it.
There's one more stop on this crazy trip.
To see something even Albert's cameras can't reveal.
But apparently, we can only get there
by leaping into a giant hole in the ground.
Because of course we do.
This is crazy.
So, it's like there's a cave that goes around back there,
and a cave that goes back there.
In all of the hours it took us to get here,
not for one moment did it look like there was anywhere
that you could go scuba diving.
Just goes to show you.
Can you tell anything about
what might be under the water based on what's out here?
Well, I think there's only one way to find out.
And that's by going in, right?
I bet we can get down around here and maybe enter in over here?
I'm not entirely sure how Albert gets me to agree to this stuff.
他就像在说 "威尔 相信我 这很安全"
He's like, "Trust me, Will. Trust me. This isn't dangerous."
You feel good?
Yeah. Just pop down and pop up.
This is one of the biggest underground lakes in the world.
At least 600 feet deep.
And this is why we came here.
One of the slowest-growing things on the planet.
By measuring them, we can go back in time.
Each inch takes a thousand years to grow.
Meaning this one has been here for more than 150,000 years.
But these stalactites, they're not just old.
They're time capsules.
As stalactites form, drip by drip...
tiny fragments of air and soil get trapped inside.
Snapshots of our planet that stretch
way back before us humans were here.
every ice age...
every forest fire
is timestamped and recorded forever.
The speed that the Earth has changed...
captured on the ultimate time-lapse camera.
That was incredible.
That's ridiculous, I didn't think it was gonna be that deep.
It just kept going.
Okay, it was scary.
I'm going to be honest.
I'm gonna keep it real.
I'm gonna keep it real. It was terrifying.
That's about as epic an undertaking as I've ever...
...been a part of.
What's crazy is the terrain.
You just never expect that's under the ground.
Like, you just...
It's like, how did that get under there?
All the way along, from the moment I woke up...
to being in this car,
everything that we experienced
was different than what I thought it was gonna be...
to the point that I could see how my perception
would have limited my experience if I wasn't following you.
And Namibia does that to me a lot.
It's just different than I thought it was gonna be.
Whatever my frame of reference has been for
caves and water and sand,
Namibia is destroying, at every turn,
what I think something is going to be.
Yeah, nature reveals itself in the most incredible ways, right?
Yeah, for sure.
Now, that's the better way to say what I wanted to say.
-你也可以用这句话 -"大自然..." 我可以用吗
- You can use it. - "Nature reveal..." I can have it?
- Thank you. - Yeah, go for it.
- I'm gonna put it on a t-shirt. Yeah. - Do it, yeah.
"Nature reveals itself in such a beautiful way."
And we're not finished yet.
Nature has more revealing to do.
Nowhere more beautifully...
than on the biggest salt flats in the world.
Those four and a half thousand miles
can reveal speed on an even more epic scale.
Once a year, the arrival of the rains...
...transform the vast salt flats...
into a mirror so large it seems to reflect everything.
During the day, it's otherworldly.
But it's when night falls
that the true magic of this cosmic mirror is revealed.
A time-lapse shows us the stars in motion.
But lock the camera to the Milky Way,
and you get to see what's really going on up there.
The movement is actually us.
Our planet spinning on its axis at 1,000 miles an hour.
We can also tell that we're racing through the solar system...
at 67,000 miles an hour.
And we're not even out of second gear yet.
Our entire galaxy is spinning about its center.
By this time tomorrow,
we will have hurtled more than ten million miles through space.
Which is frighteningly fast.
But the Milky Way is so huge,
to go all the way around. it's gonna take us 200 million years
Which sounds painfully slow.
And the craziest thing of all...
despite being hurled through space at incomprehensible speeds...
we can't feel any of it.
So, is nothing happening here...
or is the whole world invisibly moving?
Albert's camera has the answer.
You see, Will, if we track the grains,
you can watch how they bounce.
That bouncing is happening across this whole dune.
It's like it's moving like the ocean.
When we see all this, these little waves marching towards us,
It's just happening at a much slower pace, beyond our perception.
And if we zoom out further...
The whole desert is in motion right under our feet.
And the fact that it's constantly on the move
is the reason it's stayed a desert for so long.
Nothing else can get a foothold here.
No plants can anchor their roots.
No animals can arrive to eat the plants.
No town can build foundations.
So, this desert is unchanging
because it's always, always moving.
So, the appearance of permanence...
is based on the power of its impermanence.
You like that? That was just a little... Just tossing a little poetry at you.
That was a big one, though.
Our world is like a series of clockwork cogs,
all turning at different speeds.
Some too slow for us to see.
Others, too fast.
But all of them in constant motion.
The animals around us...
the land beneath us...
and the universe above.
Each is moving at its own pace...
on its own cog.
It's tempting to think that what we see is all there is.
But every minute of every day,
there are other realities living alongside us.
Each one as perfect and precious as ours.
the hidden world is actually inside me.
Hello! My name is Will!
In a crazy, frozen wilderness,
it's time to see if I've got what it takes to be a true explorer.
You didn't kill me.
You didn't kill me.
A big part of why I live my life the way I do today...
is because I was fearful as a child.
What was your biggest fear?
I was scared of everything.
I was one of the youngest kids in the neighborhood.
I got... I got bullied all the time, you know?
I think there was a certain harshness to our environment.
- But I love the challenge... - Yeah.
...of having to conquer my mind.
- This hasn't been seen or experienced by many people. - Yeah.
It's difficult to get to. It's difficult to survive in.
- We're gonna be walking around out there. - Really?
You can see all the cracks along, yeah?
The cracks, yeah. It looks like you could actually go down.
It looks like things could go wrong.
There's no part of this that's anything I've ever done or feel confident doing.
I won't lie.
Over five expeditions,
I've followed explorers into situations that were straight-up scary.
Rock, rock, rock, rock.
It was worth it to discover the Earth's wonders.
But your boy was tripping more than once.
Because when I see wilderness,
you know, nothing but nature, I get nervous.
Because I don't understand it.
So, that's the next step for me.
Throw myself into the unknown,
and try to beat my own fear.
This time, it's not about discovering the world.
It's about discovering myself.
That's my first glacier. That's my first glacier for sure.
Never walked on this much ice before.
- This is loose. - Yeah, yeah.
So, here I am in the middle of nowhere.
And Dwayne is telling me, we have to navigate off the ice
and find the ocean.
Without maps, without phones,
in one of the most extreme places on the entire planet.
So, why have you chosen this direction?
Because we've got a nice little stream there.
So, the ice is melting ever so slightly.
Sort of draining into these little channels.
And it's making its way downstream.
懂了 小溪会在冰川上形成清晰的路线 很好
Got it. The water is gonna take a clear route off the glacier. Cool.
Dwayne's job is to push me,
and my job is to let him.
This is wild.
Hold it. Hold it there.
I feel like we might just wanna go and have a look.
-好吧 听我说 -好的
- All right. I mean, listen. - Yeah.
Once you go down...
...and you successfully make it back up, I'm more than happy to go.
If I go down... and you're left up here by yourself,
-你会崩溃的 所以你也... -大概是的
- you're gonna be ruined. So, you come... - Yeah. I probably... Yeah.
- You stay with me, you stay with me. - Okay.
Ice holes like these are wildly unpredictable.
They can go down 50 feet or over 1,000.
But the only way to know for sure is to go in.
How's that feeling?
You know exactly how it's feeling.
It's scary as hell.
Nice and slow.
-越往下爬 声音就越来越大 -是的
- It gets so much louder as you get lower. - Yeah.
You're starting to trust the rope now, I can see it.
I really don't have much choice, do I?
- It better work. - Yeah.
Uh, lock off for me.
And just relax.
It's perfectly safe.
- He said confidently. - He says confidently.
- Did you hear that crack? - Yeah.
It's just constantly moving.
This is the kind of thing that half of people would say
nightmares are made of. You're climbing down into an environment
- that's constantly changing and shifting. - Yeah. Yeah. Yeah.
And there's water filling in there. "Are you mad?"
- Yeah. - That's the question.
Ha... half of us think that.
Will, you happy to go lower?
You've gotta be kidding me.
Now, look down.
Isn't that something?
- That hole just drops away into infinity. - Oblivion.
I don't think we've got enough rope to go all the way down there.
Now, dangling over a bottomless pit isn't exactly my bag,
但... 尽管可怕 也让人感到自由
but... man, scary as it is, it's liberating.
Hello! My name is Will!
And Will wants to know,
how the hell to get out of this wilderness.
Well, they say the secret is to look for clues.
Imagine what it takes... to be a fisherman...
in a desert!
You'd need a little help... right?
An armored catfish is, well, no ordinary fish.
It can survive on land.
Then, when it needs to find water...
It's a fish on a mission.
The fishermen can't find water that way.
But they can follow the fish.
Turns out, there are always clues to navigating...
even in the most barren terrain.
But knowing what is a clue...
that's the tricky part.
Look at that.
It's... it's a bird, Dwayne.
These birds, they're a clue to getting off this glacier.
There's slim pickings on the ice.
Birds here have to find water to get food.
And it will be something bigger than we've seen so far.
All this water is coming from the glacier?
And the good thing about this is...
if we follow it long enough, eventually, it's gonna take us to the sea.
Getting to the sea means what?
If it's a survival situation,
getting to the sea means you're more likely to find people.
- Got it. - It means there's food.
So, what I'm doing, I'm just looking for somewhere
to get onto the water and get the kayak in.
We're looking for a spot to put the kayak in.
- Yeah. - And this is clearly not it.
That's dangerous. That's... that's not too good.
But down there, it's probably gonna calm down quite a lot.
I know kayaking a river like this looks scary.
But it's an important step.
Because having the confidence to navigate the dangerous and unfamiliar
is at the heart of what it is to be an explorer.
First, we need to find a gentle launch point for the boat.
So "gentle" that I have to put on a waterproof suit.
很好 很好 继续
Nice, nice. Keep on coming, keep on coming.
So, I'm gonna get the raft out.
When you talked about it earlier,
I kind of saw something different in my mind.
What did you see?
Well... a kayak.
- Yeah. - Yeah.
This is like a rubber... uh, floaty.
All right. So, what we're gonna do now,
- we're gonna lower it down. - Yup.
- And by we... - You mean me?
- You're gonna lower it down. - Yeah. Yeah.
- Get ready. - Yeah.
All right, take the weight.
- Got it. - Go on.
很好 完美 我们先把它放在这
That's good. Perfect. We'll hold it there for now.
- You good? - Yeah.
- You're gonna go down next. - Yeah.
- Nice and low to the ground. - Nice and low to the ground.
Come on, Will.
I should mention again
that I am not the world's strongest swimmer.
I do not wanna go under that water.
You can already feel how cold it is.
This water's straight off the glacier.
- Have you kayaked before? - No.
-从来没有 -是的 这将是我第一次 从没划过
- No? Never? - No, this will be the first time. Never.
- What I'm gonna get you to do is stay left. - Stay left.
Because as you go to change, it's gonna change your center of balance.
That swirling brown water means
we're about to enter a strong current.
It's stirred up all the sediment.
And we're gonna go for it.
-划桨 -划桨 划桨
- Paddle, paddle. - Paddle, paddle, paddle.
Good. And keep paddling.
Keep paddling, keep paddling.
很好 干得漂亮 我们顺着水流走
Good. You did it. Let the flow take us.
That's a whirlpool.
When it's that little, it tells us there's a rock near the surface.
Give me a paddle.
See that V?
It means the water's funneling through two rocks.
We're gonna try and go straight through it.
Keep your balance. Good.
And nice and slow. Nice and slow.
- What's going on? - We're in a boil.
You can see it from the surface where it's bubbling up.
We're not going over. We are not going over.
Up and over, a second one.
Don't paddle when we've got a wave, 'cause it'll take you in.
Paddle, paddle. We're going into the rock.
- Oh, jeez. - We're good. We're good.
Well, that one was a little hairy.
Yeah, yeah, it was, it was.
That one was a little hairy.
A little bit shaky there, but we've done it.
That water is freezing through my glove.
When your hands get really cold, you stand there and you do this
to try and get the blood back into your hands.
It definitely works.
- You do feel a surge into your fingertips. - Yeah, yeah.
This is a good tip.
That trick I've learned when I was in the Arctic.
- So, when you were in the Arctic? - Yes.
All right, I just never heard a Black person say that. You're gonna...
I've trekked to the North Pole. I've crossed deserts.
I've even kayaked across seas.
But everywhere you go, you learn something new.
Your accomplishments are so important to me.
谢了 威尔 感谢你这么说
Thanks, Will. That means a lot.
'Cause, you know, I admire explorers.
I wanna be in the explorer’s club.
I don't have to pretend like these bugs are in my face out here.
- I don't have to pretend? - You're not pretending very well.
'Cause I'm trying to give you the action hero.
- I know. - I'm trying to give you...
Didn't you see me spit one out
-吐了个虫子吗 -看到了 我也得...
- a minute ago? - I know, yeah. I'm going...
...I enjoy more than doing this.
There's something about having the sky above you, isn't it?
This is like the perfect way to spend my life.
- Everything is new. - Yeah.
And there's a little bit of fear all the way through.
- That's good. That's good. - There's a little bit of fear for me
- all the way through. - You... you get past the fear.
没错 虽然这儿有湍流 有悬崖
Yes, there's rushing water. Yes, there's cliff.
Yes, you're in a place that you, you know, you have to use some of your skills.
- I'm using some of your skills. - Yeah.
Using some of my skills to navigate.
And you'll pick them up, and then you'll feel
more confident next time you come out here.
- Yeah. - Yeah.
So, when did you know...
...like full-on, you wanted to be an explorer?
It took a big incident in my life, Will.
I nearly lost my life, to gun violence. And...
...yeah, the guy, his aim was to kill me.
He pointed the gun, he pulled the trigger.
He cocked it back, he pulled the trigger again.
Incredibly, the gun jammed both times.
I survived that incident.
But it got me thinking.
I decided at that moment that I wanted my life to be more meaningful.
And that led me down a path of exploration.
For explorers like Dwayne,
fear can be the spark that spurs them on.
Or simply a hurdle they need to get over.
We're gonna go to the bay.
- Yeah. - See if we can find some mantas.
A few times a year, when everything aligns...
hundreds of mantas gather in this bay.
In massive feeding swarms.
It's an event I've always wanted to see.
So, when I'm in the water, can it be a bit overwhelming?
Yeah, it will be.
If there's too many, sometimes they could hit you.
- And does that hurt? - Yeah, it hurts a lot.
Always keep two meters away, then you'll be fine.
They've been waiting for this moment for so long.
Swimming from the boat out is definitely
one of the most stressful moments.
That feeling of not knowing what you're about to face.
It feels dangerous.
'Cause there are just so many animals in such a small space.
That's really when it can feel... the most scary.
These mantas are over 1,000 pounds.
It feels like getting hit by a truck.
There are all these emotions.
And then there's wonder at the sheer power and beauty
of these magnificent animals.
Oh, my God.
That was amazing.
It seems that fear is at the heart of so much of what an explorer does.
What I'm learning is that you need to work with that fear,
not against it.
I think we'll just leave it there.
Have you climbed before?
- In Philly. - Yeah?
Big climbing culture in Philly.
All right. Probably the best spot here, actually. That's just got...
- This looks like the best spot to you? - This is the best we've come to.
- I'm gonna let you go first. - Well, we'll just head...
-我在底下帮你 去吧 -天哪
- I'll help you from the bottom. Go. - Oh, jeez.
All right, so, you got loads of handholds here,
loads of places to put your foot. And I'll hold it.
-好 你先等着 -没错 继续往上爬
- Oh, you're holding it there. - Yeah, yeah. Go on. Get up there.
There's a ledge.
- Can you see it? - Yeah.
Uh, hold fire. I'm coming up.
Yeah, I didn't understand the me going up first, but I get it.
How's it looking?
- Not too bad. - Yeah?
Not too bad.
the key thing here is to know what's coming, if you can.
The bugs in your eyes definitely don't help.
No. No, they don't.
This stretch of river is known as Stuðlagil Canyon.
It was only discovered a few years ago.
And as far as I know, no one has kayaked through it.
So, what comes next is new territory.
What can you tell by looking at that river?
- It looks like it's going faster to the left. - Yeah.
- And then kinda sweeping back around... - Yeah.
...going slower up to the right.
Since it's going faster, I guess, it seems like it's speeding up.
- Absolutely. - Yeah.
Looking at the fact that it goes to the right,
I don't think we wanna go to the right.
- It could be shallower. - Yeah.
- It could have more rocks in it. - Oh, got it.
- We're more likely to get jammed. - Yes.
- But if the water's going faster... - Yeah, yeah.
...isn't there a possibility that there's another waterfall?
There is. There is always that possibility.
Does that mean that we wanna go up to the right?
No, to the left.
Do you have another boat? Like, what if I disagreed
and, like, if I wanted to go...
A river like this is predictable.
But I suspect the only way he'll learn this for himself
is if he takes the helm.
I hope he'll be ready for that.
Things are about to get real.
Dwayne is putting me in charge of navigating the next stretch of river.
I hope he's got insurance.
-可以走了吗 走吧 -好 走吧
- We're good to go? Let's go. - All right, let's go.
- And we're just running all the way down, right? - Yeah.
We're just gonna go all the way down. Yeah.
A little bit scary, yeah.
Just shout out what you're seeing.
- To the left right there. - Yeah.
That's a whirlpool.
- Okay. - Yes!
So, we're gonna stay... we're gonna try to stay in the center.
We got a little V happening up there.
Yeah. I guess, we're gonna take our nose right into that V.
So, it's starting to get rough.
It looks like there's churning coming from the right into the center.
好的 划桨吧 我们速度有点慢了
All right. Give me a little paddle, 'cause we're slowing down a little bit.
We wanna get up to the speed of the water.
A little bit shaky there.
没事了 可以放松点 冷静下来
We're fine now. Just relax back there. Calm down.
- Okay. - Calm down.
- Right. Right, right, right. - Okay?
More waves ahead.
Where do we want it to hit us?
We probably wanna be in it that way at the... at our one o'clock.
To our one o'clock.
Don't paddle. Absorb it.
We're not going over. We're not going over.
Good work. Keep going. Keep going.
You know, that was beautiful, man.
-我们来了 我们见证了... -征服了
- We came, we saw... - Conquered.
- We've got skills. - Yeah.
This is a bucket list moment.
威尔 作为第一次在白色水域划船的人 你简直太棒了
That was bloody good job, Will. For someone's first time on white water.
And we came down without going for a swim.
Yeah, that was... that was fantastic.
Let me bring us around. Good.
This moment deserves a toast.
Keep it in, keep it in, keep it pushing. Push it in. Push it in.
- I'm getting it in. - Keep going. Keep going.
-好了 应该可以了 -完美
- Yeah. That'll do it. - Perfect.
When I first got out here, everything seemed unknowable.
Now, I understand there's a logic to everything.
I never imagined myself being capable of this. But I did it.
Me, the kid from West Philly who hates water.
And we made it all the way to the ocean.
I know it doesn't sound like a big thing, to be able to find an ocean.
But for me, that was big.
You didn't kill me.
You didn't kill me!
Now, I can see what it means to go with the flow.
Do you know what, that's such a nice way to put it.
Look at this place.
I'm telling you, that was something, wasn't it?
I'm just happy to, like, be here, and have survived.
Yeah. There were moments where I thought, "Ooh! We're going in."
But we didn't. We didn't!
对我来说 亲临其境 与大自然融为一体
For me, it's just coming out here and being at one with nature,
考验自己 证明自己 这就足够了
and testing myself, and proving myself.
And it's not about, "Look at me. Look how strong, and great, and powerful."
It's about, "Can I apply what I've experienced here
"to another challenge in my life?"
-没错 -对我来说 体验是最重要的
- Yeah, yeah. - For me, it's just about that experience.
You know, when you start these kinds of things,
you never quite know if you're gonna get to the end.
I don't know, maybe you know you can get to the end.
- I believe I'll always get to the end. - Really?
And for me, it's not even about the end.
It's about... it's... I know it sounds so cliché, innit,
it's the journey that counts.
说真的 重要的是去经历 去体验
But honestly, for me, it's the doing it, it's the experiencing it.
It's about being out there. You can't tell me that this right now
is the best part of the journey we've just done.
That... now, that's very true.
You know what? Even now that you mention that...
...arriving even has a little bittersweet
-感觉了 -是的 就像个令人扫兴的结局
- kind of thing. - Yeah, it's like an anticlimax.
- Yeah, yeah. - Yeah.
That is true. That's true.
Hold on. What's that?
-能听到它飞过来了 时间正好 -不错
- You can hear it coming in. Good timing. - Hey, okay.
This has been a long, tough journey for me.
But in a way, it's taken me 52 years.
My mission at the start of this journey was simple.
Get out of my comfort zone... connect with the planet...
and hopefully, inspire others to do the same.
The explorers took me to the ends of the earth and beyond.
Showed me that our world is full of wonders...
...hidden forces we can't see, and barely understand.
It can be terrifying to step out into those unknowns.
But sometimes, the only thing to do is to give yourself over to the flow.
Let go of your fears.
Because when you allow yourself
to truly connect with our planet...
you realize its wonders have no end.
Yes, I like this part!
So, this is just the beginning.
Welcome to Earth, Will Smith.
Time to explore.
