Scientific paper
The structure of a typical star is investigated analytically both in the framework of general relativity (GR) and in the bimetric version of GR developed by Rosen (1980) and Falik and Rosen (1980) to eliminate singularities appearing in the solutions of the Einstein field equations. The results of the two analyses are shown to be identical for an ordinary star, but bimetric GR predicts that a collapsed star which fills its Schwarzschild radius is in hydrostatic equilibrium, while GR predicts continued collapse to a point singularity at the center of a black hole.
