But there is definite evidence that space can move at speeds well in excess of the speed of light. When the universe was born in the big bang, space expanded from smaller than the size of an atom to many light years in diameter in a tiny fraction of a second. It is also believed that if the universe ends in the big crunch, the universe will shrink to a point from many light years in a fraction of a second. In a warp field, space in front of the ship will be contracted as the result of a powerful gravitational field. Space behind the ship may be expanded as the result of a substance call exotic matter.
Normal matter has a positive energy density.
But exotic matter has a negative energy density. As a result, gravity from exotic matter is repulsive instead of attractive as in normal matter. Because the ship is not moving through space, space itself is moving, and the ship is being carried along with it, this allows the vessel to travel faster than light without facing the problems of relativity. The ship itself would have to be protected from the extreme forces around it with some sort of an anti-gravity field. Before you get to excited, there are some problems with this theory for warp drive.
