Hawking hopes to solve the mystery of the birth of the universe. 1970s, Hawking applied quantum mechanics to explain the phenomenon of black holes. In the next 30 years, it will become more difficult to explain the whole universe with quantum mechanics. Hawking wants to find a theory that can perfectly explain the whole phenomenon of the universe to explain the birth of the universe from 65.438+0.37 billion years to the present, but after many years, even if he is infinitely close to him, he still has not reached a conclusion.

According to his theory of quantum mechanics, the birth of the universe was caused by the Big Bang, which was the product of an infinitely small compressed substance exploding under supergravity (which can also be understood as infinite density).

Hawking's "grey hole" theory holds that matter and energy will be released into the universe again after being trapped by a black hole for a period of time. In his paper, he admitted that his initial understanding of the horizon was flawed, and light could actually cross the horizon. When light escapes from the core of a black hole, it moves like a person running on a treadmill and slowly contracts by radiating outward.

"Classical black hole theory holds that no matter and radiation can escape from a black hole, while quantum mechanics theory shows that both energy and information can escape from a black hole." Hawking also pointed out that the explanation of this escape process needs a theory that can successfully integrate gravity and other basic forces. In the past 100 years, no one in physics has tried to explain this process.

Stephen william hawking, a famous British astrophysicist, made a surprising remark after admitting the existence of aliens: he claimed that it was theoretically feasible to fly humans into the future time machine, and the required conditions included wormholes in space or spacecraft with a speed close to the speed of light. However, Hawking also warned against going back to see history by time machine, because "only crazy scientists would want to go back to the past and' reverse cause and effect'."

Extended information Hawking predicted:

Hawking, a famous British physicist, said on June 13, 2006 that the survival of mankind depends on finding a new place to live in space, because the possibility of the earth being destroyed by a catastrophe is getting higher and higher. He predicted that man would be able to enter Mars within 40 years.

Hawking said that humans may stay on the moon in 20 years and colonize Mars in 40 years. He said that developing new living space in space is the key to maintain the continued existence of mankind, because the risk of the destruction of the earth is getting higher and higher. "Unless we find another star system, we can't find a place as good as Earth."

Hawking visited Hong Kong on June 5438+03 and delivered a speech. Hawking said that if humans can avoid killing each other in the next 100 years, it is possible to permanently settle in space without relying on the resources provided by the earth. "For the sake of human survival, it is very important for human beings to expand into space.

There is an increasing risk that life on earth will be destroyed by disasters, such as the sudden deterioration of global warming, nuclear war, genetically modified virus, and even other dangers we don't know yet. "
