Re:Near-topic: G forces

This is all coming from memory, but it may help others to provide
correct
facts <G>.

The record for G`s that a human body can stand is in the region of 50
G`s
(yes, fifty). This was proven by a USAF doctor who straped into a rocket
propelled railchair and then rode said chair into a water bath to slow
it
down. The G`s he experianced peaked at 50 G`s momentarally, but did
suffer
for his pains (tempory blindness due to detached retenas was one).
Please
note, the G`s peaked at 50 G`s only temparly.

As for suviving continus G`s, if you are lying down, you can take high
G`s
for longer and higher G`s than fighter pilots, who do the grunting to
prevent the blood pooling in the extremities. If you are lying down, the
heart only has to pump the blood along the same plain, instead of trying
to
pump it against the G`s you are experancing.

As for how long to travel intersteller distances, I remember someone
worked
out that if a ship left earth and accelerated at a continus 1g halfway
there, and decellerated same at the halfway point, a voyage to alpha
centauri would take 10 years with a velocity of 0.5 C at turnover (I
think,
it was a long time ago, might have been on fifth C).
