Saw this picture and it twigged a question in my mind.
If you filled a space ship with oxygenated PFC or similar, then would that remove the effect of inertia holding back acceleration? Inertia, as I understand it, is a problem because the liquid in our bodies is slower to accelerate, but if the entire container was filled with fluids and moving at the same rate, then all of the liquids should be moving at about the same rate. You could probably do the same thing with a tank as well, if mass is a concern.
I got suspicious, it can't really be this simple? So I got out a used a used teabag from the pot, put in a cup of water and started sloshing around in my sink as hard as I could. Overall the teabag stayed in the middle of the cup. So at least on a small scale it checks out. It could be that on a prolonged scale (multiple Gs for hours at a time) the tiny difference in density would be enough to cause you to get pressed against the back wall. I don't know.
Thoughts?
