Maybe some friends don't know Hawking very well. Let's take a brief look at Hawking first.
Hawking was born in 1942 and died in 20 18 at the age of 76. His life was both great and unfortunate.
Hawking was born in a family with a good academic atmosphere. His father Frank graduated from Oxford University and is an expert in tropical diseases. His mother Isabel studied philosophy, politics and economics in Oxford. Therefore, Hawking received a good education from an early age. /kloc-at the age of 0/7, he was successfully admitted to Oxford University to study natural science and successfully obtained a first-class honorary degree. Later, he transferred to Cambridge University to study cosmology, but unfortunately, at the age of 2 1, he was diagnosed with amyotrophic lateral sclerosis, which is also commonly known as gradual freezing. His movements became slower and slower, his body began to show symptoms of paralysis, and even his speech began to become vague. His attending doctor even diagnosed that he would not live for two years, but fortunately Hawking survived.
Although Hawking's life has been extended, he has lost his mobility and can only spend the rest of his life in a wheelchair, but he has not bowed to his fate. Since fate doesn't allow me to act, I will develop my brain to the limit!
Hawking used only a wheelchair to study cosmology and black holes in his later years, proved the singularity theorem and black hole area theorem of general relativity, put forward the black hole evaporation theory and the borderless Hawking universe model, and won the honorary Lord of Britain and the Commander's Medal of the British Empire. 1988, Hawking also published A Brief History of Time, which became a must-read for many science lovers.
About Hawking's prophecy: Hawking has made many predictions, three of which are closely related to the fate of mankind.
(1) artificial intelligence
At present, the development of artificial intelligence has risen again, the most famous of which is Alpha, which was created by scientists and defeated Ke Jie, the world's number one Go player. In the future, artificial intelligence will penetrate into all fields of our lives, but Hawking proposed before his death that artificial intelligence may evolve itself in the future, even out of human control, becoming a new life form, evolving self-awareness and threatening human survival.
(2) Leave the earth
The problem of rising earth temperature has been puzzling mankind for a long time. With the rise of the earth's temperature, the future climate of the earth will no longer be suitable for human survival. In addition, asteroids and meteorites outside the earth are also in danger of hitting the earth. The only way for human survival is to leave the earth. Although there are no planets suitable for human survival in the solar system except the earth, there are a large number of planets in the universe, and there are probably planets suitable for human survival in the Milky Way outside the solar system.
(3) Aliens
Since there may be planets suitable for life besides the earth, it is not surprising that there are aliens, but Hawking believes that human beings should not take the initiative to contact aliens, because it is likely to bring disaster to human beings. If aliens knew about the existence of the earth, they would probably plunder its resources. Once this happens, human beings will be unable to stop the invasion of aliens and human civilization will perish. Think about the disaster that Columbus brought to the local natives after he discovered America.
Reliability of prediction: As a great scientist, Hawking's prediction is highly reliable. Regarding the first two predictions, both artificial intelligence and climate change are developing in the direction of Hawking's prediction. What about aliens? Who can deny their existence? No one can say no for sure, the vastness of the universe far exceeds human imagination, and aliens may be just the tip of the iceberg of the mystery of the universe.
