Over time, prophecies generally have two outcomes. First, it has become nonsense. Second, it becomes a reality. In the history of the world, many celebrities have made prophecies, and some people's prophecies have become "nonsense" and are gradually buried in history. Of course, there are also some prophecies made by people that eventually become reality. Let's say Hawking.

Hawking had predicted that the Earth on which humans lived would become warmer and warmer over time, eventually turning into a large fireball. At that point, the Earth will lose all life. This prediction for Hawking has actually fulfilled the first half, and now the temperature of the earth is getting higher and higher. As global temperatures rise, humanity will face different problems.
In addition to the above prophecies, Hawking also has two people whose prophecies are relatively highly concerned. First, in an interview in August 2010, Hawking predicted that the earth would be destroyed within 200 years, that is, 2210. Hawking said that if the earth continues to be so endlessly logged, then the earth will be destroyed in 200 years. Of course, Hawking also pointed out that if humans still want to survive, they can only immigrate to other planets.
Second, Hawking also made a prediction in November 2017 that he would go extinct by 2600. The cause of extinction mainly comes from humans. Hawking believed that The earth's resources would be depleted by 2600. By that time, as global temperatures rise, the earth will become a big fireball, and it will no longer be able to adapt to human survival.
Do you think Hawking's other two prophecies are credible?
