Can a Hypothetical Device Save a Human from Extreme G-Force Acceleration?

[Jane]

Have you been reading al the above comments?
We have been pointing out the lethal consequences to bodily liquids and tissues at that level of acceleration - with or without 'Anti-g' measures. How can you then suggest the traveller would be in a position to move about? She would be DEAD.

Okay, got it, sorry.

If it's not possible for a human to withstand so much g, how do they live in the international space station?

The acceleration on the ISS is approximately 0 g. The ISS is not firing its engines like a big jet pack.

And how about Apollo 10 ultimate speed record? 11.08 km/s with people inside. It's speed, not acceleration, but it was high as well. Shouldn't it be extremely uncomfortable for them?

Speed, by itself, has no adverse effect.

A hypotetical costume diminishes the force that affects her body.

All costumes produced to date obey the laws of physics, one of which is F=ma. If the costume reduces net force then acceleration must also reduce (assuming that the wearer refuses to be cut into small pieces with reduced mass). There simply is no way to reduce net force and keep high acceleration.

A hypotetical costume diminishes the force that affects her body. That 20,408 g that would've destroy her otherwise.

Newton's second law says F=ma. There is no magical pixie dust exception for fancy costumes. Your acceleration is determined by the force on your body.

The best one can do is to try to spread that force out evenly so that the associated stresses are not too extreme (g suits, recumbent position, water bed, liquid breathing, etc). But 20,000 g's is too extreme to mitigate that way.

Edit: Dithered too long and @Dale beat me to it.
