“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” ... “On a dive to the bottom of the Mariana Trench, which is nearly 7 miles deep, you're talking about over 1,000 times more pressure than at the surface,” Feldman said.

What would happen to a human at the bottom of the Mariana Trench?

The pressure from the water would push in on the person's body, causing any space that's filled with air to collapse. (The air would be compressed.) So, the lungs would collapse.

What happens to you in the bottom of Mariana Trench?

• If you’re already dead and drift down slowly from the surface, pressure in your body will likely equilibrate with sea pressure as you’re on your way down. So you end up at the bottom in largely your current size and shape - just sort of dead. And the deep-sea worms are still happy.
