/kloc-will there be humans on the earth in 0/00 billion years?

It is strange that a common-sense astronomical knowledge can ask such a wonderful question, and everyone rushes to answer it, browsing the answers of gentlemen at will. Except for a few reliable ones, most of them dance to the tune of "100 billion years". Most of our knowledge of astronomical geography comes from this geography textbook for primary and secondary schools. BIGBANG, the universe is only 65.438+0.3 billion years, and the earth has turned around the sun for about 4.6 billion years. According to the predicted life of 100 years, it can still run for about 5 billion years. Is that so? Astronomers and geography books say so. As for whether it is true or not, no one knows that people have the longest life span 100 years, but few people reach this age. "Life is short", just spend these sixty years. Life is seventy years old. Who knows what the fate of the earth will be and when human beings will survive? God knows.

Therefore, no matter how long the life of the earth is, it will not exceed 5 billion years. Why? Astronomers say that the sun can "burn" for 5 billion years at most. The earth moves around the sun. Where did the earth go without the sun? It has long been swallowed up by the sun and integrated into the "stomach". Humans must have disappeared billions or billions of years in advance, and not only humans, but all living things will perish. Because there is no air and water on the earth that produces life carriers, why should we raise life? As predicted at the beginning of A Dream of Red Mansions, they are all white and in the barren land. Beautiful scenery like this will last for a billion years or more: it will never be seen again after two billion years. At that time, the earth was not even as good as the moon now, and it might be similar to Mars and Venus. The loess and rocks under high temperature are in a rolling heat wave, and life has long since ended. All civilizations created by human beings will be destroyed to zero, leaving no trace, desolate and silent. How terrible!

In the face of such an outcome, isn't it ridiculous to talk about whether human beings can still exist after100 billion years? Hawking is a great astronomer, isn't he? His study of astronomical geography has theoretical depth, and he seems not optimistic about the future of the earth and mankind. A black hole is a monster, so attractive that even light can't escape its clutches. Fortunately, the nearest black hole to the earth is more than 3000 light years (? ), otherwise it will be really scary. There are alien objects, but they always threaten the survival of the earth. It is said that Jupiter is big and its volume is 1.300 times that of the earth. It attracts and absorbs a large number of alien objects, which is a barrier for the earth to avoid disasters, but it is also destructive. Its strong attraction not only affects the deviation of the sun center, but also plays a role in attracting and promoting asteroids. From time to time, small celestial bodies will be sucked out, and a few may fly to the earth, while some pose a great threat to the earth. It is said that a small celestial body hit the earth 60 million years ago and wiped out the dinosaurs. If you come back later, the fate of mankind will be "confessed"! Therefore, human beings should not think too much, so in the long run, after 100 million years, it is still left to astronomers to study. Generally, people who eat melons should focus on the present and live their own lives.

However, astronomical meteorology, foreign invasion, geological changes, such as earthquakes, plagues and other disasters, of course, we must actively guard against them. Especially foreign objects, come and go without a trace. Astronomers are always on the lookout. They can take better precautions, but they have to be prepared to reduce losses, which is what human beings must do to protect themselves. In particular, protecting the earth's natural environment is the most important thing. We can't waste the earth without a bottom line and make things that are difficult to "digest" like plastics everywhere. One paradox is that the more "civilized" human beings are, the more dangerous the earth is. When can people control themselves?

Take this time period alone. 654.38+000 billion years later, on earth. There must be no humans. And the planet earth no longer exists in the universe. So, let's analyze it in a scientific way. 654.38+00 billion years later, we and the earth. What is fate?

A big bang universe was formed 654.38+04 billion years ago. More precisely, it formed the Milky Way. 4.6 billion years ago. Cosmic dust formed our earth. So from this point in time, 654.38+00 billion years later, the earth itself. The inside will burn out. The ground has subsided. Form a small black hole. If he had formed a small black hole before. A big star beside the earth. First, the internal combustion is exhausted. Forming a large depression. And bigger black holes. Then the earth will be sucked in. This cycle should occur within 654.38+00 billion years.

If the earth is sucked into the black hole of another star. There will be a new explosion. Produce new clusters of galaxies. In the new cluster of galaxies. There is earth's material. But there is no earth.

Big explosions often happen. Just outside the milky way galaxy. Infinity is happening. The universe has no boundaries, and there will be some perseverance at any time. It's burnt out That is, the life of this star has reached its limit. And it will form a new small explosion point. And the universe is constantly producing new information groups and new stars.

This is the earth. The destination is between10 billion years and10 billion years.

Humans, where are we going?

If there are no civil wars and natural disasters, give them to mankind. Three thousand years. At the current speed of human science and technology development. You can find n in the galaxy. A planet similar to the earth's living environment. Moreover, human beings can develop both Fu Guang aircraft and superluminal aircraft. Space migration is not a dream.

So humans. Yes Living and living on different planets. Communicate with each other. In this way, even if we encounter the collision of small stars again, we have, um, the choice of an immigrant planet.

This problem is analyzed from the perspective of scientific rationality. 100 billion years later, if human beings still exist, the technology at that time will go against the sky, and now it is indescribable. The return trip is now beyond our imagination.

Ha! I have heard that some people are worried about the country, but I have never heard that some people are worried about whether the earth will still exist after 1000 billion years.

I am really ignorant. It turns out that there are still many people worried about heaven! /kloc-will the earth still exist in 0/00 billion years? I dare say the gods don't know, but what I know is; You must leave in a hundred years. [Cover your face]
