For example, one set of calculations suggests that quantum fields living at the edge of the warp drive bubble essentially blow up to infinity as soon as you turn the thing on, which would be bad.

These do not come from physical theory. They're just statements that ... to violate the weak energy condition because to set up a warp bubble you need to use a ball of negative mass, of negative ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks.

In Star Trek, dilithium crystals — whatever those are — are critical to the operation of a starship’s warp drives. But a Texas professor thinks he can make a baby step towards a warp drive ...
