WebThe big bounce hypothesis attempts to replace the cosmic singularity with a cosmic contraction and bounce, thereby explaining the initial conditions that led to the big bang. The flatness and horizon problems are naturally solved in the Einstein-Cartan-Sciama-Kibble theory of gravity, without needing an exotic form of matter or free parameters. WebApr 12, 2024 · The dRGT massive gravity represents a comprehensive theory which properly describes massive graviton field. Latterly, the exact spherical solutions are identified for the black hole in the dRGT massive gravity theory. In this paper, we derive Bousso’s D-bound entropy for the black hole solutions of dRGT massive gravity. By an …

The only working theory of gravity that we have is general relativity. According to GR, the size of the singularity is zero. That is basically the definition of the word "singularity." People are working on extending GR to include quantum mechanics, but we don't yet have a theory of quantum gravity. rejection simulator ivy
