What are the "five great prophecies" left by Hawking?

20 18, 18, Stephen hawking, a great theoretical physicist in the contemporary era and a scientific "treasure" in Britain and even the whole world, passed away, and the world scientific community mourned for it.

At 2 1 year-old, Hawking suddenly became ill, his whole body muscles gradually atrophied, he could not speak, and only three fingers in his hand could move. After that, his body was trapped in a wheelchair, but his thoughts wandered in the universe, and many important theories of the universe were put forward and demonstrated.

People prefer to call Hawking a popular scientist, because he is always willing to popularize complex scientific research that ordinary people can't understand, introduce more people into the hall of physics and imagine the universe.

As the most popular and representative scientist, Hawking left five shocking predictions for mankind before his death.

Forecast? one

The earth will be destroyed in 200 years.

"Doomsday theory" is not new, but it has to be seriously considered when it comes from a heavyweight scientist like Hawking. What's more, Huo Lao added a clear time limit to the life of the earth-200 years.

20 1 1 In an interview with BigThink, a famous American intellectual video sharing website, Hawking said that the earth will be destroyed within 200 years, and there is only one way for human beings to survive: emigrate to other planets. Hawking believes that the earth will be destroyed by a catastrophe in the future, such as nuclear war or greenhouse effect.

He also said on many occasions that the only chance for human beings to survive for a long time is to stay away from the earth and adapt to life on the new planet. Unless human beings colonize outer space in the last two centuries, they will disappear from the world forever.

"For the sake of human survival, it is very important for human beings to expand into space. The risk of life on earth being destroyed by disasters is increasing, such as the sudden deterioration of global warming, nuclear war, genetically modified viruses, and even other dangers we don't know yet. "

Hawking also appealed that if we want to continue our progress, we must look at outer space, so he strongly supported manned space flight research. He also pointed out that human beings are expected to travel in time by spaceship, and the long journey from the earth to the edge of the galaxy takes only 80 years, which brings technological possibilities for human beings to colonize outer space.

On October 20 17, 1 1 year 10, Hawking supplemented and updated the prediction of the destruction of the earth. He believes that in 2600, the population of the earth will increase dramatically, energy consumption will increase, and the earth will become a "fireball".

Hawking predicted? timetable

In 2032, the earth entered the ice age and the world became cold.

Man must leave the earth in 2060.

In 2 100, human beings entered outer space and new species appeared.

The earth will face destruction in 22 15.

In 2600, the earth became a fiery "fireball".

Forecast? two

Time travel is not a dream.

In the scientific community, time travel was once considered a "fallacy".

"In the past, I often avoided talking about this issue because I was worried that someone would label myself as a' freak'. But now, I am no longer so cautious. " Hawking said, "I have been obsessed with time for a long time. If I had a time machine, I would visit Marilyn Monroe in its heyday, or aim my telescope at Galileo in the universe. Perhaps I will go to the end of the universe and solve the mystery of the annihilation of the whole universe. "

Hawking is not only a beautiful fantasy, but also analyzes the practical problems of realizing time travel in the future from a scientific point of view.

Forecast? three

The brain may exist "independently"

At the age of 2 1 year, his whole body muscles gradually atrophy, and only a few fingers can move. But in this case, he has made outstanding achievements in the study of the universe and black holes and won the respect of the global scientific community.

According to the media, Hawking has been using "stump" to express his thoughts in "the smartest brain in the world".

Hawking also expressed his views on body and mind. He firmly believes that the human brain can exist independently, not attached to the body, and the mind, like a program stored in the brain, can be copied. Hawking said: "The brain is like a computer to some extent, from which we can copy' programs' into the computer, which is feasible in theory."

Forecast? four

Aliens may be around us.

At the launching ceremony of the Royal Society of Science in London on 20 15, Hawking said: "There must be other forms of life in the infinite universe."

"Maybe alien life will stare at us." "No matter whether there is extraterrestrial intelligent life in the end, it is time for someone to formally invest in it. We must understand this problem. "

By then, this project will use some of the largest telescopes in the world to go deep into the universe and capture any radio waves and laser signals.

Forecast? five

Artificial intelligence may lead to the extinction of mankind.

20 14 On May 3rd, the famous physicist Stephen Hawking said that artificial intelligence may be not only the biggest event in human history, but also the last event when discussing the new film Transcendental Hacker starring Johnny Depp. What he means is that artificial intelligence may lead to the extinction of mankind.

Hawking believes that artificial intelligence can solve most problems in the world, including human diseases and social problems, and AI has this potential. If AI is properly deployed, it will tap unlimited potential, and if it is improperly deployed, it can threaten the survival of mankind.

Once artificial intelligence is out of control, human beings will be limited by evolution and cannot compete with it. According to Hawking's prediction, AI will quickly eliminate millions of jobs in the future.

When the artificial intelligence alpha dog defeated the Chinese and Korean Go players in succession, this statement almost made people see the possibility of realization.

2017165438+16 October, Hawking once again warned the world that science and technology are expected to reverse some hazards brought by industrialization and help eliminate diseases and poverty, but artificial intelligence needs to be controlled.

To be honest, Hawking's prediction is a bit scary: in 200 years, the earth will be destroyed, aliens will look at us, and artificial intelligence will destroy mankind ... Is it feasible?

At present, we don't know, or maybe he just reminds the world in this way: be kind to the earth and be kind to life.
