Reply to comment by mcabeeaug20 in Could being submersed in a sealed tank of fluid help humans survive heavy G acceleration in outer space? by cheeze_whiz_shampoo

That's a cool scene when he drops the mouse in. But yeah, there are breathable fluid, but our lungs aren't able to deal with the viscosity. That alone causes traumatic injury. Also, the movie "Event Horizon", they go in tanks of fluid.

IIRC in the Abyss, the breathing fluid was real and the rat was actually breathing it on film (the scene got censored for the UK release due to perceived animal cruelty). Bud, however, wore a helmet full of coloured water and held his breath.

In Event Horizon, the crew still breathe gas through masks. The medic mentions in the opening scene: "When the ion drive engages, we'll be pulling about 20 Gs. Without a tank, the force would liquefy your skeleton." Another comment notes that breathing gas is still viable to about 20G, above which fluid breathing would be required.

It was real for the mouse, in real life military tests the fluid is too heavy and it damages human lungs to the point of incurable issues. So we need a little work. Something lighter and easier to move in and out of the lungs but provides the same benefit.

Isn't it being "heavy" directly related to how well it handles the pressure though? Like if it's light enough that our lungs aren't damaged, then it's light enough to have the same issues are breathable air.
