Can a circulating light beam produce a time machine?
Ken D. Olum, Allen Everett
In a recent paper, Mallett found a solution of the Einstein equations in which closed timelike curves (CTC's) are present in the empty space outside an infinitely long cylinder of…
Time travel paradoxes, path integrals, and the many worlds interpretation of quantum mechanics
Allen Everett
We consider two approaches to evading paradoxes in quantum mechanics with closed timelike curves (CTCs). In a model similar to Politzer's, assuming pure states and using path integ…
Magnetic Fields from Phase Transitions
Mark Hindmarsh, Allen Everett
The generation of primordial magnetic fields from cosmological phase transitions is discussed, paying particular attention to the electroweak transition and to the various definiti…
A Superluminal Subway: The Krasnikov Tube
Allen E. Everett, Thomas A. Roman
The ``warp drive'' metric recently presented by Alcubierre has the problem that an observer at the center of the warp bubble is causally separated from the outer edge of the bubble…
