The universe is a general term for the vast space, various celestial bodies and diffuse matter existing in it. The origin of the universe is an extremely complex issue. Many scientists believe that the universe was formed by a big bang that occurred about 13.7 billion years ago. The stored matter and energy in the universe are gathered together and concentrated into a small volume. The temperature is extremely high, the density is extremely high, and huge pressure is generated instantaneously. After that, a big bang occurred. The reaction principle of this big bang was recognized by physicists. They are called quantum physics. The big bang dissipated matter, the universe continued to expand, and the temperature dropped accordingly. Later, all galaxies, stars, planets and even life appeared in the universe one after another.

Everyone is living in the era of the highest scientific level in the contemporary era. Science, as a practical method for understanding the universe, has been developing vigorously. Until today, mankind has gone to space. However, the universe still leaves us with too many unsolved mysteries. Only through science can mankind truly understand the universe.
