Title |
Admissible coordinates and their role in protecting chronology | |||||

Abstract |
To confront relativity theory with observation, it is necessary to split spacetime into its temporal and spatial components. The (1+3) timelike "threading" approach involves restrictions on the gravitational potentials $(g_{\mu \nu})$, while the (3+1) spacelike slicing approach involves restrictions on $(g^{\mu \nu})$. These latter coordinate conditions protect chronology within any such coordinate patch. The influence of chronology violation on wave motion is examined in stationary G\"odel-type universes. |
