Hawking's Quotations-Thinking and Predicting the Future

Stephen william hawking was born in Oxford, England. He is a famous physicist at Cambridge University, one of the greatest physicists in modern times, and one of the great men who enjoyed an international reputation in the 20th century. On March 20 17 14, Stephen hawking died at the age of 76. Remember this great physicist ... the day he was born was the day Galileo died. The day he died was the day Einstein was born.

Hawking once had many wonderful quotations, including some worrying ideas and predictions about the future. Let's have a look. (The following text comes from the Internet)

Hawking's Quotations 1: "Aliens" are watching you.

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."

He said, "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. "

It is reported that this project will use some of the largest telescopes in the world to go deeper into the universe and capture any radio waves and laser signals.

Hawking's Quotations 2: In the Millennium, human beings must emigrate to other planets, otherwise they will be "extinct".

Hawking said in a speech in Los Angeles that in the next 1000 years, it is almost certain that the earth will be destroyed by a catastrophe, such as nuclear war or greenhouse effect. Therefore, he stressed that human beings must migrate to other planets. Griffin, director of NASA, also said that species on a single planet cannot survive forever.

In the solar system, besides the earth, Mars is the best choice for human habitation. However, it will take decades for manned exploration of Mars to be implemented, and it will take 450 days for a round trip.

Hawking said: "Human extinction is possible, but not inevitable. I am an optimist. I believe that the development and progress of science and technology can eventually bring mankind out of the solar system and reach more distant places in the universe. "

Hawking's Quotations 3: Intelligent machines are the "terminators" of real human beings.

Hawking has repeatedly said that "the complete development of artificial intelligence may lead to the demise of mankind."

According to Hawking, artificial intelligence technology does bring convenience to human life in the initial stage of development, but machines are likely to redesign themselves at an increasingly fast speed. However, human beings are limited by the speed of biological evolution, unable to compete with it and eventually surpassed. This turning point of artificial intelligence beyond human intelligence was named "singularity" by the scientific community.

In fact, Elon, CEO of American Space X Company and famous prototype designer of Iron Man? Microsoft founder and philanthropist Bill Musk? Gates also warned to pay attention to the "harm" of artificial intelligence. MIT professors, scientists, employees of companies such as Google, IBM and Microsoft, and investors related to artificial intelligence also jointly published an open letter expressing the same concern.

Hawking's Quotations 4: "Black hole" does not exist? Only "grey hole"

Hawking pointed out in a paper "Information Preservation and Weather Forecast of Black Holes" that black holes do not exist, but "grey holes do exist", which shocked the physics community again.

Hawking put forward the famous "Hawking radiation" theory in 1976, that is, the black hole radiates to the outside world in the form of energy while its mass decreases during its formation. However, once the black hole is concentrated and evaporated, all the information in it will disappear, which contradicts the theory of quantum mechanics that the information of this substance will never disappear completely. This is the so-called "black hole paradox".

For more than 30 years, Hawking tried to explain this contradictory view with various speculations. Now it seems that he gave a more convincing answer. Hawking admits that his initial understanding of the "horizon" of the black hole boundary is flawed, and light can actually cross the horizon. He said that black holes never completely shut themselves down, and matter and energy will be released into the universe again after being trapped by black holes for a period of time.

Remember to look up at the stars, not down at your feet. No matter how hard life is, please keep a curiosity.
