When were Hawking's five prophecies before his death?

20 10 hawking was interviewed by BigThink, a famous American intellectual video sharing website, and put forward five human predictions:

1.In 2032, the earth entered the ice age, and global warming: the problem of global warming has long been known to the world, and we humans have also taken corresponding measures to establish a low-carbon and environmentally-friendly life. But human activities will inevitably lead to global warming, which may eventually make the earth's temperature unbalanced, thus entering the ice age. This is the closest of Hawking's five predictions to the present.

2. In 2060, humans left the earth and immigrated to Mars: 1969, and humans landed on the moon for the first time. After the American moon landing program ended, no one landed on the moon for half a century. This is not the stagnation of science and technology, it is preparing for the future explosion.

3.2 100, when human beings entered outer space, new species appeared: In 2006, Hawking attended an academic seminar in Mumbai, India, and said: If human beings do not destroy themselves in the future 100, the scientific level of human beings will be expected to develop to the point of landing on other planets in the solar system, and it is not bad to enter outer space and breed new species from a new environment.

In 4.22 15, the earth will face catastrophic destruction: there are countless predictions about the end, but none of them really hit the nail on the head so far. But the earth in 200 years, maybe. At that time, human science and technology must have been much higher than now, and the earth could not stand any global war.

In 2600, the earth will become a fiery "fireball": Hawking believes that with the growth of population, the earth's energy consumption will become larger and larger, and if no better renewable energy can be found to replace it, the earth's resources will be exhausted by human beings sooner or later.

Extended data:

On March 20 18 14, the famous physicist Stephen Hawking died at the age of 76. Mr. Hawking has been devoted to exploring the mysteries of the universe and has made great contributions to human exploration of the universe. Hawking scientists had many famous theories and scientific speculations before his death.

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. "

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.

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.
