the people who got crushed by the pressure just weren't trying hard enough

By god, you're right anon. Let's put some extra oxygen tanks in there and send a few more billionaires down. No further action required.

How do you open a hatch from the inside that was bolted shut from the outside?

Amazing that science enables people without any concept of science to blab their stupidity to a world wide audience.

some oceangate level of thinking there

But then they might end up getting

You just have to be faster than pressure

All I could have wished for was for them to become a beautiful song in the water, but they went out with a single horrid clap.

A rare 4chan theist

Water is slightly compressible, and so are thick steel springs. Now imagine each vertical column of the ocean as a kilometers-tall spring. The top wire loops' weight compresses the bottom loops with great force but there is no way this compression can be released because these columns are tightly packed inside the steel ocean's volume and in every location at a specific depth there is the same pressure from the weight above. Unless... someone makes a hollow ball with atmospheric pressure inside and spirals down a spring, bearing the pressure difference between its inside and the loops of spring it's wedged between... and then cracks. Whoever is inside is not surviving that.

Should've covered themselves in oil to repel the water duh

Someone try to convince elmo he can do this, quick!

I hear that if you do that, you might even get a nice German car (Benz)!
