Static pressure on it's own doesn't really "do" anything though. You could have the thinest piece of solid material with 10 million atmospheres on either side and the material doesn't care since forces cancel out. Difference in pressure is where shit goes pop or crush depending on the direction.
Divers frequently go to pressures of 500+ PSI without issues directly from the pressure
Nearly all the issues at that depth are from the physiology of breathing gasses at that pressure
That's 34atm or about 330m. Nobody is diving that deep on a regular basis. It's the world record.
This statement is incorrect. Pressure directly affects materials. Its just without pluging the hole with a part of your body you don't actually feel the difference. In static 10 million atmospheres stuff like metal should show some measurable shrinkage. The larger the object, the more shrinkage you will measure.
Yes, you are technically right. Little too much hyperbole on my part, but the bulk modulus of solids in typically in the tens to hundreds of gigapascals
