Thanks. I've basically done a quick overview of the latest developments in warp drive physics, and share your doubts.

Tachyons are wierd. If they had infinite energy, they would travel at the speed of light; but the less energy they have, the faster they go! If a tachyon has no energy, it has an infinite velocity! Also, the mass-energy of tachyons is meant to be expressed by the square root of -1 (try it out on a calculator). These are some messed-up particles!

Presumably, tachyons are unable to travel backward in time in OGC, as is hypothesised in real life.
