G forces on the human body?
I saw a video about this magnet train that runs through a tunnel and all the gass and everything is sucked out of the tunnel so it's basically a vacuum. They theorize they can eventually get a train that can go around 3500 miles per hour through a vacuum.
This is an interesting if not amazing accomplishment on its own, but can a human being survive the g force of going that fast? I know jet pilots pass out without flight jackets and they never go near 3500 MPH. Is there something about moving through a vacuum that lessens G forces? Certainly astronaut must go pretty fast without use of flight jackets.
I guess my real question is, can this train ever really work the way they want it to or will gravity keep them down?

G forces only work when something is accelerating. Not when its at the same speed.
(if they did you would always feel forced to the back of your seat when you are driving a car)
Simply put, if the train accelerates at a low rate it can reach whatever speed it wants without you on the inside ever noticing it.
Jet pilots experience the G forces because they reach those speeds very fast, sometimes in less than 10 seconds.
