What are the effects of "High-G's" to human beings? And can you tell me the site where you got the info pls!!

Answer 1

Well, many years ago I read a sci fi story about how a cargo had to be delivered to Pluto in a hurry. So they got their top-gun rocket pilot to accelerate at 3g to the halfway point and decelerate at 3g the rest of the way. When he arrived, he was a shuffling incontinent wreck and had to be put in an old people's home.

Answer 2

High positive G's (downwards, like gravity) will cause the blood to drain from your head and you can suffer 'grey-out' or black-out.
High negative G's can cause red-out, which is an oversupply of blood to the brain.
