Well, professor Jim Woodward has been working on his Mach/Lorentz thruster for a while now and has a working setup in the lab, and multiple publications in peer-reviewed journals. With his theory it is in fact possible to build startrek-style impuls engines, warpdrives and wormholes. And it all fits in our existing theoretical knowledge. He has a book out, published by Springer-Verlag (they don't publish nonsense):
