[00:00:00]Most people don't understand how deep the ocean really is. Imagine walking off the coast into the water. At 10 m, 33 ft, you're already experiencing an entire [music] additional atmosphere of pressure. At 214 m, you're passing the verified [music] record for a human diver with no equipment. At 830, you're the depth of the tallest [music] building on Earth.

[00:00:20]At 1,000 m down, no surface light reaches you anymore. You're only a tenth of the way down. At 11,020 m, you're in the territory of the deepest known military submarine. At 3,800 m, you hit [music] the Titanic. And just above it is where the infamous OceanGate submersible imploded. The deepest recorded natural point is 10,984 m, 6.8 [music] mi. You might have heard of this point. This is Challenger Deep, located in the Mariana Trench. If you put Mount Everest into the water upside down, there would still be over a mile until you got to the bottom. The ocean covers 71% of our planet, and we've explored less than 20% of it. Whatever is down there, we're only just beginning to understand it. Follow for more science facts that will completely change how you see the world.
