The Big Bang is the starting point. What is the state before the starting point?

Your question just asked about the”dead hole” of the Big Bang universe theory. The Big Bang universe theory has a shortcoming, that is, it cannot explain what happened before the Big Bang. The beginning of the Big Bang is regarded as the absolute”zero hour”. The state is also very strange. Physical quantities such as pressure, energy density, and temperature are all infinite, and the curvature of space-time is also infinite. Because of this infinity, physical theories are untenable at this time, and no physical theory can explain it. So it is the”singularity” that makes physics a headache. In order to solve this”singularity”, physicists have spent a lot of effort, but still did not find a solution.
