Eli5: Underwater pressure

301 views

Why do people, submarines, and essentially everything that dives too far into the water get crushed? I get that it’s the weight of the water, but shouldn’t the pressure just come from the top and not everywhere, as if there were a weight on you?

When you smash something against a table, the smashing is from you pushing down and the table pushing up.

The weight of the water above you is pushing down, and the water below you is pushing up, thus you crunch from both sides.

Edit: and all around. The water is being compressed everywhere so it’s also trying to squeeze into you from the side, if it can.
