| Abstract: | ![]()
The existence of nontrivial causality violation is a peculiar property of the space-time around a naked singularity. In the case of Kerr metric witha > m we have found that for a particular class of geodesies that could in principle violate causality, the conditions for causality violation are never satisfied.On leave of absence from Institute of Astronomy, Polish Academy of Sciences, Warsaw, Poland. |
