New Development of the Big Bang Theory

The Big Bang is an explanation based on observation and physical theory. One hundred years later, this theory has been further improved and explained. Since the universe came out of the big bang, will there be a small explosion after the big bang? The answer is yes. We can never see the big bang, but we can see the small one every day. According to the small explosion to deduce the scene of the big explosion, we can further improve the theory of the big explosion. Conclusion: the big bang of the universe is also accompanied by the annihilation of matter, which is a coexistence of two kinds of big bang.
