Has the universe been reborn 20 times? Hawking: the universe has no starting point, the big bang goes back and forth

Hawking once put forward his own point of view, he thought that the Big Bang has happened 20 times so far, and the law of the cosmic cycle is like this, first exploding, then gathering, then exploding, and then gathering again. This is one of the most important predictions before Hawking died, and he went on to say that the future universe will still cycle like this, so what’s the matter?

Two or three things about the Big Bang Theory

① Energy singularity

According to the knowledge learned and the records in textbooks, most scientists in the field of Astrophysics and all over the world believe that the universe was born in the big bang. The explosion is in a singularity, the energy fluctuation of which is extremely active. It is released from the form of explosion, and at the same time, it carries a lot of material. Finally, these materials gradually merge and form the universe.

Now scientists see that the big bang theory is the basic way to study the universe. At the same time, the big bang also left some clues.


For example, the popular cosmic microwave background radiation also proves the Hubble theory that the universe is expanding. It should be noted that it also starts to expand from one point. However, when studying this theory, some scientists also questioned: if the universe was exploded, what shape were they before the explosion? What’s the shape after the explosion? These extended questions have attracted the attention of many scientists, including Hawking.

For example, many years before Hawking died, when he studied the theory of black holes, he made a public statement that black holes exist so huge that they will never disappear, but they will explode.

② Black hole big bang

Suppose that in a limited time, if the expansion speed of the universe keeps slowing down, then all the celestial bodies in the universe will die out. At this time, there is an active black hole in the universe, and all the celestial bodies in the universe will eventually be swallowed by the black hole. Of course, there are also large and small black holes. The big black hole finally devours the small black hole. For a long time, there is only one huge black hole left. However, this black hole will not exist all the time. It will slowly shrink because its internal energy is extremely precipitated. If the compressed energy and mass reach a singularity and boom, the big bang will start. This explosion will release a huge amount of energy and carry a lot of energy With all kinds of matter, a new universe is born.

③ Cyclic cosmology

Just now this theory is called circular cosmology.


When Hawking and other scientists began to study further, they found that if black holes absorbed all the celestial bodies, they would release gravity and photons, which are called Hawking radiation in the research field.

During the big bang period, the only clue is cosmic microwave radiation. Just now, it has been said that scientists can further describe the ultimate process of the formation of the universe by studying Hawking radiation and cosmic microwave radiation. At the beginning of the big bang, there will be a very bright mark, which is also called Hawking point in the academic circle. However, scientists can’t find a bright mark in the universe However, the discovery of 20 Hawking dots, these bright dots, all prove that the big bang cycle has been about 20 times.

Scientists’ conjecture about the universe

Now will the universe continue to exist, or continue to cycle as Hawking predicted, or not, but at a certain point in time, the universe finally stops expanding, black holes no longer absorb celestial bodies, and the universe is in a delicate balance.

It is the common expectation of all mankind that these answers, which are difficult to determine, will be answered in the long river of human civilization.
