They could feasibly have a prototype within 5 years!!!

Happy New Year indeed everyone.

With this, we will be able to warp to follow to the U-F-0.

There is a common belief about the warp drive being a marvellous thing, but I say it don't work. Why?

Warp drive is supposed to work as follow: a spaceship folds the space around it, and this produces a gravitationnal field which accelerates the ship. On some variants it can accelerate at higher speed than light.

What I say is that this is strictly equivalent to a surfer who would surf on a wave he produced himself with blowing on the ocean. Admitting he could do that with a 100% efficiency, he would simply recover with his surf the energy he used to blow. Or the force exerted by surfing and the force necessary to create the wave are the reaction of each other, and thus they cancel each other with a perfect exactitude.

A curved space is a mass. We can create a warp drive very easily: take a heavy iron ball (for warping space) and a balsa model spaceship, and let them float inside the shuttle or ISS. You would see the spaceship model approaching the iron ball, attracted by its mass (to be exact we should do the experiment into free space, not aboard the ISS which has a stronger gravitationnal field. On Earth one could use a Cavendish-like experiment). In order to maintain the acceleration, we should keep a constant distance between the spaceship model and the "space warping" iron ball, by attaching the iron ball to the model spaceship, so what it is alway in front of it and it exerts a constant acceleration on it. But in doing so, the global center of mass receives no acceleration, and we just have a useless "modern art sculpture" unable to move, because the attractive force (by the warping mass) and the force necessary to move the warping mass are the reaction of each other.

Anyway warped space has a mass, that you have to move too, and unfortunately it is much heavier than any spaceship.

This reasoning is also true, I think, with any distortion of space, including warping having the effect of a negative mass.
