Why wouldn't this "warp-drive" work? Assuming we can build a flywheel that can survive near light speed and have an onboard power storage or beamed energy that can spin it up to that speed and back down again
1) Telescoping link between two capsules, they are free to move towards each other
2) flywheel in first capsule starts spinning. As it nears light speed from what I've heard about relativity it will start getting more massive instead of actually getting any faster
3) This extra mass will give it a stronger gravitational field right?
4) Both capsules now fall towards each other in accord with Newton's law of gravitation, however because the front capsule is now so much more massive it doesn't move noticeably as opposed to the rear capsule which basically blasts off towards the front capsule
5) After time, t the flywheel slows down, the masses of the two capsules becomes equal again, however the rear capsule stays in constant motion toward the front capsule because of Newton's first law
6) Just before the rear capsule runs into the front one the linkage is made to snap rigid which causes the rear capsule to transfer momentum to the front capsule
7) Because they are the same mass again their new velocity is v/2 where v is the velocity gained by the rear capsule in it's initial gravitational acceleration
Thoughts? I say it's a warp drive because using the visualization of spacetime where it is a flat elastic sheet, the flywheel dents the sheet which sucks in the rear capsule but just before it gets there the dent disappears but then reappears later further down the line to repeat the process.
