A recently published paper that was published in Classical and Quantum Gravity gives hope that this could work. There are four fundamental forces in the universe: gravity, electromagnetism ...

It's possible to manipulate space-time in such a way that ... Whether an Alcubierre warp drive is allowed is ultimately a question for quantum gravity, which we do not yet have a solution for.

Besides quantum theory, general relativity is one of two pillars of modern physics – our working theory of gravity and of the very large, of planets, galaxies and the universe as a whole.
