    So, I understand that because water is not compressible, animals without air in their bodies are safe at such high pressures in the deep sea, but what I’m wondering is what would it look like if a human in the deep sea was suddenly exposed to those pressures, as would happen if a submarine rapidly pressurizes? I know the lungs would collapse and whatnot because the air would be pressurized into I’m guessing a liquid, like how propane sloshes when under pressure in a tank, but what else? What causes the instant death? Maybe the water shoots into nose/mouth so fast it acts like a bullet and applies a bunch of force to the walls internally?

      During the implosion you’ll have to contend with the walls of the sub and the water rushing it at a high percentage of mach 1 if not at supersonic speeds. That includes shards of carbon fibre and the big heavy titanium end plates. The air bubble inside will also be compressed to well above 400 atmospheres as the inertia of the incoming water causes an over pressure scenario. This compression heats up that air bubble to temperatures were a plasma is formed and for a brief moment the imploding sub would be the only visible light source down there. Basically anyone in there at the time is converted to a red mist. Think A-train running through that chick at the start of the boys, or that kid flying through that sheriff in brightburn for an idea of the result.
