When supernova occur all the mass of star get concentrate at at very small point and if the star has very very large mass then after supernova it turn into Black hole. But at the time of big bang entire mass of the universe came into a small point and that is a very very huge mass then why at that time the explosion occur and the black hole wasn't created.?? Please answer my question. Thanks
A star having a mass __ times the solar mass, after passing through different stages becomes a supernova.
