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

So people would be forced 'back' against the wall of the tank but just at a slower rate compared to an air filled environment?

You can use a liquid that matches the average human density. Water is pretty close already.

Where would you need a very large acceleration? 1 g is no problem, 2 g is likely acceptable for a long time, 3-5 g is okay for the time needed to reach Earth orbit.

Yup, basically. And when they are pressed against the wall then the person will be subject to the same G force as the tanks movement.

But the force is not relevant. Unless their body shatters at some point, they are virtually the same density as the rest of the water.

By your logic, no part of the spacecraft could survive any part of the journey, because it's touching itself and the engine.
