The universe is the general name of the vast space and all kinds of celestial bodies and dispersed substances existing in it. The origin of the universe is an extremely complicated problem. The universe is a material world, which is in constant movement and development. For thousands of years, scientists have been exploring when and how the universe was formed. Today, many scientists still believe that the universe was formed by a big bang about 654.38+037 billion years ago. The matter and energy stored in the universe gather together and condense into a very small volume, with extremely high temperature and density, which instantly produces great pressure, and then there is the Big Bang. The reaction principle of this big bang is called quantum physics by physicists. The big bang dispersed the matter, the space expanded continuously, and the temperature dropped accordingly. Later, it appeared in all galaxies, stars, planets and even life in the universe.
