00:00One second has a thousand milliseconds. That's how long it took the deep sea to crush the Titan
00:04into scrap. 400 milliseconds. Too fast for the five men inside to even feel fear.
00:11June 18, 2023. They set out to look at the Titanic, entombed 3,800 meters down.
00:17Instead, they stayed there forever. At the surface, the pressure on your body is about
00:22one atmosphere. At that depth, it's 3,800. Imagine a full-grown male polar bear standing
00:28on every square inch of your body, all at once. Almost everyone reached the same conclusion.
00:33The killer was the crushing pressure of the deep. It sounds simple. It looks obvious.
00:39And it hides one fatal flaw. Because at that exact depth, there's a soft, squishy fish living just
00:45fine. The blob fish. So if water pressure were the gun, then in those 400 milliseconds,
00:51who actually pulled the trigger. To crack a case like this, the fastest route is never to stare
00:56at the dead. It's to find the one who should have died too, and walked away without a scratch.
01:00In this deep sea case, that's a fish. A famously ugly one. Thousands of meters down, the Titan imploded.
01:08The blob fish floats there, perfectly fine. Why? Because inside its entire body, you cannot find a
01:15single pocket of trapped air. It's essentially a lump of jelly that can't be compressed. Whatever
01:20pressure is outside, its body pushes back exactly the same. Equal on both sides. The pressure
01:26difference is zero. The deep sea simply has nothing to grab onto. The real killer was never depth.
01:32It was the pressure difference. That deadly gap between inside and outside. The Titan carried five
01:38people, which meant it had to bring a whole atmosphere of air down with them. Outside, it was
01:43380 atmospheres. Inside, one. That gap of 379 atmospheres. That was the bullet. The trigger
01:52wasn't pulled by the ocean. It was pulled by the breath they had no choice but to carry down.
01:57Once you see that, every terror in the sea suddenly makes sense. Why can't you just hold your breath
02:02and dive deep? Because your lungs are a balloon you carry with you. As you descend, the water crushes
02:07inward. Your eardrums get driven in from the outside. And surfacing too fast is worse.
02:13The pressure releases, the gas in your lungs expands instantly, and it can burst them from
02:17the inside. There's something even stranger. Over a century ago, workers on underwater construction
02:23crews surfaced and collapsed in agony. Some died on the spot. For years, no one understood why.
02:30Then they figured it out. Under high pressure, nitrogen in the air dissolves into your blood.
02:35Rise too fast, the pressure drops, and that nitrogen turns back into bubbles inside your veins.
02:40It's called the bends. And it can kill you without a single wound.
02:45Now let's go back to the real question. If the only true enemy is the pressure difference,
02:49then it's the material and the shape that decide who lives and who dies.
02:53A sphere is the strongest shape there is, because pressure comes at it equally from every direction.
02:58But a sphere has a weakness. It cannot be welded shut like a pipe. It needs a window.
03:03It needs a seal. And the Titan's window was a viewport rated for about 1300 meters.
03:09They were going down to 3800. The hull was carbon fiber. Not steel. Carbon fiber is strong against
03:17stretching, but under crushing pressure, layer by layer, it can delaminate and fail.
03:21The Titan had already made dozens of dives. Each one left invisible damage inside the material.
03:27Eight days before the implosion, a former employee sent an email that read,
03:31this is going to end in disaster. He was fired for saying it. Other experts wrote letters.
03:37They were ignored. And here's the detail that stays with you.
03:40The pilot, at the back of the vessel, was pressing a button to release ballast, to slow the descent.
03:45The moment it gave way, he was the closest to the wall. He may never have known what happened.
03:51400 milliseconds. No warning. No sound. No chance.
03:57One more thing. And it might be the most unsettling part of all.
04:01Deep sea exploration isn't only tragedy. It's the last piece of this planet that hasn't been carved up yet.
04:07Beneath the ocean floor lies frozen methane, studied as a future fuel.
04:11There are fields of rock holding cobalt, nickel, and manganese.
04:15The metals that build batteries, electric cars, and the entire modern age.
04:19And the most critical resource of all. Submarine cables.
04:23The video you're watching right now, every word you type, almost all of the world's internet traffic,
04:28travels through just a few cables on the ocean floor.
04:31Submarine cables are the nervous system of the modern world.
04:34And that nervous system is far more fragile than you think.
04:37One deep sea earthquake.
04:39One underwater landslide.
04:41Even one anchor dragging across the seabed, and a whole region can lose its connection.
04:46We're used to information arriving at the other side of the planet instantly.
04:49We rarely stop to think that everything holding it together is just a few lines lying in the dark,
04:53out of sight.
04:54The deeper humanity goes, the clearer one thing becomes.
04:58Our control over this planet is nowhere near as solid as we believe.
05:01And the real age of the deep sea has only just begun.
05:17It's not just a few lines like these in the dark, but it makes you better sense.
05:22Even bettering balconies is from the body and other powers.
05:31But for the Jeremiahrokles willicker the whole entire world.
05:36It's still covering the space.
05:36Yeah, probably.
05:37Whatever you want is the scale of one thing.
