i know that moving the theory about moving the space around a space ship and the ship actually stays still. but is this actually possible? theoretically it is, but physically is it?
also would out bodies be able to with stand the g force of moving that fast?
is traveling faster than the speed of light physically possible?

I assume you are referring to the Alcubierre drive. It is "mathematically" possible, but no one knows yet if it is physically possible. Most scientists seem to think it's not possible, but there are experiments underway which are attempting to detect the necessary phenomenon. With the Alcubierre drive, you would essentially not be accelerating, so there's no problem of g-force.

No it is not possible. The Alcibierre drive can be filed with time travel - the maths allows it but we do not have and cannot imagine how to make the materials.

Impossible with current technology.

No body can travel through space at faster than the speed of light... period. This is because as a body accelerates it gains mass, and maintains a constant requiring of a force, proportional to the rate at which the mass gains, thrusting it. As a body reaches the speed of light, it comes to the point where its mass becomes infinite. There is no force in the universe that can accelerate an infinite mass. Therefore, no body can travel through space at, or faster, than the speed of light.

The difficulty behind the concept of the alcubierre drive isn't in g-forces or exceeding the speed of light (neither principle is actually being applied or violated in this approach). The problem is physically obtaining and controlling the massive amounts of energy required in the mathematics of warping space itself.
Just to give you an idea, the amount of power needed to move just a few atoms using the alcubierre method is equal to the total power output of 3 suns. You'd need the total energy of several galaxies combined just to move something the size of a shoe. To move an actual vessel would require an amount of energy exceeding all of the power available in the observable universe.

best answer...we don't know

NO,not with what we know and have now.

The speed of 299,792,458 metres per second can be achieved and exceeded by simply free_falling into a SMBH (Super massive black hole.)
During free_fall the accelerating body will feel no G_force effects. (in accordance with inverse square rule)

The free_falling body will *Always* perceive that (local ) light propagates at exactly c.

How are you going to handle the mass of your body?
2014-07-19 10:36 am
Of course not!
Think about it: light is the carrier of the electromagnetic force. It travels AT the speed of light. Never faster.
All the particles that make up your body, or the materials comprising a spacefaring contraption are held together by electromagnetic forces. These forces cannot ever move faster than light, hence no silly contrivance or astronaut strapped within can ever move faster than light.
Cheers!
