G forces and space?

[Manok101]

I'm a big sci fi fan and most shows seem to hint that you still feel g's in space. My question is would you in a vacuum?

If you were accelerating, yes.

unless of course your ship has inertial dampeners

Yes, unless you are on star trek - I think they only seem to feel G forces during explosions when they grab something to avoid falling over. Never seen them get pinned to the back of the bridge when going into warp drive.

G forces are the result of acceleration and deceleration - an atmosphere is not necessary. This has stuff to do with relativity, I think. Have you seen the centrifuges they put astronauts in? They spin you round really fast. The centrifugal force pushes you outward from the centre, making you experience g forces. This force is felt throughout the universe, and so is not subject to atmospheres.

Well that would be because of the inertia dampening field. It's the same thing that stops them all from being ejected through the front viewscreen when the vessel goes from Warp Factor 9 (1,516 x light speed according to the TNG technical manual *GEEK ALERT* ) to a dead stop in under 2 seconds.

It's all complete nonsense really though

Like badger said, air has nothing to do with whether you "feel" gravity or not. my physics prof showed us a neat demonstration involving two ~2m tubes, each with a feather inside. For one tube, he sucked all of the air out with a pump to create a vacuum and left the air in the other tube. he then spun the tubes around to watch the feathers drop and the feather in the vacuum tube fell as fast as a rock. really cool

Yes, as long as Mach's Principle is true.

Sci-fi gets round it using inertia negation.

An early attempt was cavorite, a gravity-shielding material invented by H.G. Wells.

I won't be starring in any sci-fi movies nor going into space with Richard Branson, so this doesn't affect me. My clothes in the washing machine might have a problem though lol
