The question aims at mechanical effects of high pressure ("skin rupture etc.") which do not exist: The human body is very much like a water balloon with a few bones in it which is happy at any depth, even though it is mechanically very weak. The problem are the chemical and biological effects of gases at high partial pressures. If, as a gedankenexperiment, the blood could be oxygenated outside the body in an artificial lung, the problems would disappear, I suppose. | |

The current human depth limit is due to toxicity of the breathing gases as pressure goes up, go deep enough and there's no gas that's safe to breathe. However, there are liquids capable of dissolving enough gas--there have been demonstrations of small animals surviving them. However, square-cube interferes, human lungs wouldn't be able to inhale/exhale it. The problem is mass, not viscosity. | |
