What is Hawking's real contribution to physics? How many Nobel Prizes have you won?

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'."

Stephen William Hawking

As for the key point of time machine, Hawking emphasized the so-called "four-dimensional space", which scientists named "wormhole". Hawking emphasized that the "wormhole" is around us, but it is too small to be seen by the naked eye. They exist between space and time.

He pointed out that everything in the universe is neither flat nor real. Close observation shows that all objects have holes or folds, which is a basic physical law and applies to time. Time also has tiny cracks, wrinkles and gaps. The space smaller than molecules and atoms is named "quantum bubble", and "wormhole" exists in it.

Alien theory

Stephen Hawking said in the documentary "Follow Stephen Hawking into the Universe" broadcast by the American Discovery Channel 20 10 on April 25th that aliens are very likely to exist, but human beings should not take the initiative to look for them, and should make every effort to avoid contact with them to avoid the attack of the dark forest! (Theory mentioned in Liu's Three-body)

Hawking believes that it is "a bit too risky" for humans to actively seek contact with aliens, given that aliens may plunder the earth's resources and then leave. "If aliens visit us, I think the result may be similar to that when Christopher Columbus set foot on the American continent. This is not a good thing for the local Indians. "

Interstellar migration

When Hawking was interviewed by BigThink, an American intellectual video sharing website, in August of 20 10, he made another astonishing remark, saying that the earth will be destroyed within 200 years, and there is only one way for human beings to survive: to emigrate to other planets.

Hawking said that if human beings want to continue, they must emigrate to Mars or other planets, and the earth will die sooner or later. Hawking said: "mankind has entered an increasingly dangerous period, and we have experienced many life-and-death events." Because of the genetic code of' selfish greed' carried in human genes, human beings are plundering the resources of the earth bit by bit. Humans can't put all their eggs in one basket, so they can't bet on one planet.
