Abstract. General relativity, or the general theory of relativity, is the geometric theory of gravitation. Although general relativity is not the only relativistic theory of gravity, it is the simplest such theory that is consistent with the experimental data. Nevertheless, a number of open questions remain, the most fundamental of which is how general relativity can be reconciled with the laws of quantum physics to produce a complete and self-consistent theory of quantum gravity.
We all know that the most famous equation in physics is \(E=mc^2\)
