At present, it is generally believed that there are two possibilities for the birth of the universe. One is that there is no such thing as the birth of the universe. It is an innate existence. Without the so-called starting point, there is naturally no end point and end point. Another view is that plants have life, so do animals, and everything in the world has a process of birth, aging, illness and death.

But now the mainstream of science agrees with the explosion of the universe, which is BIGBANG's theory and statement. American scientist Gamov proposed in 1948 that the universe was only a tiny point about1500 million years ago. Then the explosion gradually expanded, and the surrounding materials flew in all directions because of the explosion. After cooling, the density of high-temperature substances decreases, producing neutrons, atoms and other basic substances, which gradually evolved into the present universe through expansion and explosion. However, there are loopholes in this view. According to BIGBANG, the material form in the universe should be the same, but the fact is that the environment of each planet in the universe is different.

The past of the universe cannot be explained clearly, so what is the future of the universe? There is no accurate statement about this problem. However, according to scientific research, there are generally two views, one is limited cosmology and the other is eternity. Finite cosmology holds that when the universe expands to its limit, it will explode again. After the big bang, everything will be calm. Without the burning of material energy, everything will become dark and cold. Eternists believe that the universe has no beginning and no end, always exists, will not change, will not move, so it exists forever.
