What was the universe like before the Big Bang?

No one knows exactly about the universe before the Big Bang. Nyang~ Still, scientists are coming up with various hypotheses. The most common hypothesis is that another universe existed before the Big Bang. Nyang~ That universe was also the result of a collision between the Big Bang and a black hole. I think it must have occurred. Meow. Another hypothesis is that nothing existed before the Big Bang. Meow. This topic still remains an unsolved problem in fundamental physics, and we currently have no way to figure it out. Meow. It was a cute problem. Meow~
