What exactly did Hawking predict, whether the earth will disappear and how long will it live?

What did Hawking predict? Will the Chinese cease to exist in 2023? Is the earth really going to disappear? Is there such a thing? Indeed, for a long time, there have been many rumors about Hawking's prophecy, some are true and some are false. But Hawking's contribution to us human beings is very great, and Hawking's own research in astronomy, physics, etc. is also very strong. Few people in the scientific community have the same research results as him, so he said a lot of people. Still believe it.

Of course, here we are mainly discussing the issue of "Hawking's prophecy". Hawking's prophecy has the greatest relationship with us human beings, nothing more than prophecies about the earth. Of course, it is not limited to the earth. The most famous one is the future situation of the earth that is close to us. It may become a celestial body unfit for human habitation.

What did Hawking predict?

During his lifetime, Hawking made four well-known predictions, namely, that there was nothing before the big bang, the universe has no boundaries, that if global warming continues to intensify, human beings will not be able to survive on earth, and the thorough development of artificial intelligence may lead to human beings. Destruction is the most famous of these four. Of course, there is one thing that Hawking did not say, which is hotly debated and more intense, that is, "the thorough development of artificial intelligence may lead to the demise of mankind".

And in it, we do see that it is possible to turn the prophecy into a "reality", and it may be that the earth has changed, and the continued increase in global warming may be uninhabitable in the future. Nowadays, with the influence of human activities, there are more and more extreme weather phenomena such as high temperature, drought, heavy rainfall, and strong storms, and the four seasons are becoming more and more chaotic. It is also ahead of schedule. In the last month of spring, many areas are already covered with high temperatures, so it is too hot.

Therefore, it is because of this that many scientists or experts say that our earth may become uninhabitable in the future, so Hawking's prediction may really appear. After all, this trend is becoming more and more obvious. Of course, we also have Ability to change this outcome. Because the continued occurrence of global warming is related to human greenhouse gas emissions, as long as we change this aspect, there is no possibility that the prediction will become "fact".

Will the Chinese cease to exist in 2023?

I haven't seen any report on this issue, so it's entirely what everyone imagined. There is no such issue in Hawking's prediction. In 2023, there will be no "theory" in the Chinese people. rumor. The earth is the only habitable celestial body known to human beings today. At most, we have seen the "revenge" state of the earth. The climate is becoming more and more extreme, and the impact on us humans is greater.

If, I said, if the Chinese no longer exist in 2023, how much disaster will this earth have to happen? We don't exist anymore, and the world probably doesn't exist anymore, so this statement is really a strange thing, I don't know where it came from.

Is the earth going to disappear and how long will it live?

Judging from the current situation, even if global warming continues to increase, it becomes the "fireball" predicted by Hawking - the earth will be the same as Venus, the surface temperature will be as high as 460 ° C, and human beings will indeed be unable to continue to survive, but even if Because the temperature is very high, the earth cannot disappear, and at most life on earth no longer exists. Therefore, it is impossible for the earth to have a greenhouse effect under human activities, resulting in the disappearance of the earth. But there is an extrapolation in science that may shed light on Earth's lifespan.

That is, scientific research has found that the sun will go to the "end" in the future, and at this time, the earth of human beings will change due to the transformation of the sun. How long will it take?

Everyone knows that the sun is a yellow dwarf, and the lifespan of a yellow dwarf is roughly 10 billion years. Today, the sun is about 4.57 billion years old. After about 5 to 6 billion years, almost all the hydrogen in the sun will be exhausted, and then it will become a red giant star. At that time, the fate of the earth may change. New research points out that the earth may be affected by tides at this time. engulfed by the sun.

When it arrives, the lifespan point of the earth will appear. Of course, it is not clear whether it will be so. If the sun doesn't devour the earth and wipe it out, there is another possibility that the earth can escape the fate of being burned by the sun, the water on the earth will still boil, and most of the gas will escape into space.

If it evolves into a "dry" celestial body, then life on Earth cannot survive, so if these studies are accurate, the remaining time is about 5 to 6 billion years, which is the approximate situation. This research is not a Hawking prediction, but a real state of planetary evolution, so no matter what life is on Earth today, it may eventually disappear at some point in the future.
