Scientists announce a physical warp drive is possible
There is still the problem of FTL information transfer violating causality, but I have wondered if sub-light warp drive might not be physically possible.<p>It wouldn’t be FTL but it would be a kind of “massless” drive in that it would get around the propellant mass issues with accelerating to near light speed. It would “cheat” by warping space instead of accelerating at all in the conventional sense.<p>The Centauri system is a little under 5 years away with such a drive.
