There would be no acceleration; the ship does not move in the normal space. The acceleration (such as stretching of the space) occurs within an infinitely thin border of the bubble, but that border is far enough from the outer walls of the spacecraft.
As an example, take a sailor inside a submarine. The submarine may be moving pretty fast underwater, but the sailor is not feeling any pressure of water - there is some other shell, well away from him, that takes care of that. As far as the sailor is concerned, he is not moving anywhere.
Yes.
Supposedly from the point of view of the object being ‘accelerated’, it actually doesn’t move or notice any kind of G force of any kind.
Supposedly.
Whether or not a practical actual working model does what it is supposed ot do, well...
..that would be the interesting part.
As your speed approaches or reaches c, your apparent mass reaches or exceeds that of a planet.
Your actual mass does not change at all.
But you would be gravitationally slinging things around you.
Again, supposedly.
If mankind lives long enough, we may actuially see whether or not this is true.
Yeah but, with all this stretching of space going on, what happens when you try to come back the other way?
Does space start getting compressed again? What about "stretch" marks?
You could run into a wrinkle in time.
I may need to go out and sit on a rock in my back yard to ponder this.
