We show that Lorentzian (traversable) wormholes and time machines with
semi-classical space-times are unstable due to their violation of the
null energy condition (NEC). Semi-classicality of the energy-momentum
tensor in a given quantum state (required for semi-classicality of the
space-time) implies localization of its wavefunction in phase space,
leading to evolution according to the classical equations of motion.
Previous results related to violation of the NEC then require that the
configuration is unstable to small perturbations."
Tuv(Matter) = 0 in practical exotic vacuum low-power star-gate/warp drive.
Guv + /\zpfguv = 0
is all we need. Tuv(Matter) is ignorable.
The long-range phase rigidity of the macro-quantum Vacuum ODLRO damps out these random micro-quantum fluctuations for same reason /\ is so small! The saucers fly, don't they? ;-)
