05/27 Warp drive possible?

(from Slashdot) |
| xxx.lanl.gov/abs/gr-qc/9905084 A spacetime is presented for which the total negative mass needed is of the order of a few solar masses, accompanied by a comparable amount of positive energy. This puts the warp drive in the mass scale of large traversable wormholes. The new geometry satisfies the quantum inequality concerning WEC violations and has the same advantages as the original Alcubierre spacetime. |
