Semi-classical wormholes and time machines are unstable

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? ;-)

time is a strong enough condition to imply localizati

of the wavefunction in phase space. This means the tim

Wormholes and time machines cannot be both predictable

and stable.

Susskind [7] has recently argued against the existence

of wormholes connecting otherwise causally disconnected

regions."
