Quantum effects in the Alcubierre warp drive spacetime
The expectation value of the stress-energy tensor of a free conformally invariant scalar field is computed in a two-dimensional reduction of the Alcubierre “warp drive” spacetime. The stress-energy is found to diverge if the apparent velocity of the spaceship exceeds the speed of light. If such behavior occurs in four dimensions, then it appears implausible that “warp drive” behavior in a space...

The expectation value of the stress-energy tensor of a free conformally invariant scalar eld is computed in a two-dimensional reduction of the Al-cubierre \warp drive" spacetime. The stress-energy is found to diverge if the apparent velocity of the spaceship exceeds the speed of light. If such behavior occurs in four dimensions, then it appears implausible that \warp drive" behavior in a spacet...
متن کاملThe Alcubierre Warp Drive in Higher Dimensional Spacetime
The canonical form of the Alcubierre warp drive metric is considered to gain insight into the mathematical mechanism triggering the effect. A parallel with the Chung-Freese spacetime metric is drawn to demonstrate that the spacetime expansion boost can be considered a 3 + 1 on-brane simplification for higher dimensional geometric effects. The implications for baryonic matter of higher dimension...
متن کاملNull Geodesics in the Alcubierre Warp Drive Spacetime: The View from the Bridge
The null geodesic equations in the Alcubierre warp drive spacetime are numerically integrated to determine the angular deflection and redshift of photons which propagate through the distortion of the “warp drive” bubble to reach an observer at the origin of the warp effect. We find that for a starship with an effective warp speed exceeding the speed of light, stars in the forward hemisphere wil...
متن کاملSETI, the Velocity-of-Light Limitation, and the Alcubierre Warp Drive: An Integrating Overview
In SETI (Search for Extraterrestrial Intelligence) conventional wisdom has it that the probability of direct contact by interstellar travel is vanishingly small due to the enormous distances involved, coupled with the velocity-oflight limitation. Alcubierre's recent "warp drive" analysis [Class. Quantum Grav. 11, L 73 (1994)] within the context of general relativistic dynamics, however, indicat...
