Singularities in solutions of the Einstein equations for a static spherically symmetric field
- 12 Downloads
The nature of the singularities in the solutions of Einstein's equations for a static spherically symmetric field is investigated as a function of the choice of additional conditions. It is shown that the principal singularity — the Schwarzschild sphere — can be produced or established by certain conditions without changing the physical assumptions or the gravitational equations themselves. Different solutions are obtained which are equivalent from the point of view of observations since the theoretical variations of the astronomical effects are far beyond the limits of experimental possibilities.
