NAKED SINGULARITIES, TIME MACHINES AND IMPULSIVE EVENTS |
Abstract _ |
If a curvature singularity is globally naked then the space-time may be causally future ill-behaved admitting closed time-like or null curves which extend to asymptotic distances. This generates a Cosmic Time Machine. Here the conjecture that a Cosmic Time Machine gives rise to an impulsive event is considered in more details. |
