Huge concentration of energy!! 1.It's told that before the big bang everything was comressed in a very small space (as small as an atom, some say as small as a coin). My point is even if matter was not created at that time, there should be some limit to the concentration of energy (or whatever was present then). Is there such a limit? 2. If everything was concentrated in a small space, what was outside it? 3. Isn't it possible that at extremely high concentration of energy, it can turn into matter/ If yes? how can matter be constricted to such a small space.
