The "doomsday" of the earth may come early! How long can humans live on the earth?

As the only living planet known to mankind, the earth has been carrying creatures for millions of years, including extinction period, Little Ice Age and so on. For today, human beings' scientific exploration ability is getting stronger and stronger.

Therefore, the calculation of life on earth is becoming more and more obvious. How long it will take for our earth and how long it will take for human beings to be on the earth has always been concerned. Although this seems to be far away from us, it is not far away if you think about it carefully.

According to common sense, the life span of the earth must be longer than that of human civilization. We depend on the earth instead of the earth. Perhaps you are welcome to say that without human beings, the natural evolution cycle of the earth may be longer, and with human beings, it will become more and more complicated. Even now, life on earth may be affected.

How long will the life of the earth be if accidents are not considered?

According to a published report, in the 20th century, scientists discovered the most reliable method to determine the age of the earth, which is called isotope geological determination. This method also makes us realize that the earth has experienced about 4.5 billion years, plus some periodic changes. To be more accurate, the age of the earth should be 4.6 billion years.

However, how long the life of the earth will be in the future may need to be decided according to the changes of the sun, because scientists have discovered the life of the sun. End date? .

According to scientists' prediction, the ultimate life span of the sun is 65.438+00 billion years, but now it has existed for more than 4.55 billion years, so if the sun appears in the next few billion years as predicted by scientists, it will become a star. Expansion? The Milky Way, so if we don't consider the influence of human beings or other factors on the earth, what about the earth? End date? Will be swallowed up by the expanding sun, which is the ultimate life of the earth.

So after about 5 billion to 6 billion years, the hydrogen in the sun will be almost completely consumed, which will affect the earth, or it may be the earth's? End date? .

Of course, if something unexpected happens to the earth, then the life span of the earth is likely to be shorter, that is, affected by other factors. End date? Or come early, or it may lead to the destruction of the earth. For human beings, human events determine some unexpected situations, right? In advance? Model.

How long can humans live on the earth?

As we said above, if there are no accidents, there are still billions of years on earth, so human civilization can last for billions of years. However, unexpected circumstances may lead to the extinction of human beings, or make them unfit to live on the earth in advance.

For example, human beings wantonly cut down trees, pollute water resources and emit polluted gases, which are accelerating the situation that the earth is not suitable for human habitation. From the changes of today's ecosystem, we can all see that today's earth environment is very bad, and high temperature, drought, strong storm and heavy rainfall are all affecting human survival.

And these effects are also fatal. In 2020, there have been many natural disasters with record highs, so it will speed up the time when human beings are not suitable for living on the earth. If it continues, the earth may even make human beings uninhabitable in a hundred years. At the same time, in addition to these effects, events such as the impact of space rocks or asteroids on the earth may also be developed, which may also cause the destruction of the earth and threaten the survival of mankind.

Everyone should have heard that the director of the National Aeronautics and Space Administration of the United States warned that there may be the possibility of an asteroid hitting the earth in the lifetime of human beings, so these are accelerating the time for human beings to survive on the earth.

Face this? Accident? Situation, humans may also need to think of one for themselves? Back road? Only in this way can we avoid problems perfectly and let human civilization continue to an inevitable stage.

Space migration or the future choice?

With so many possible accidents, human beings really can't face these catastrophic problems. Then space migration is indeed a great choice for mankind. Now the whole world is implementing immigration plans, which is expected to turn Mars into human beings. The second earth? Alleviate the earth problems facing mankind today. According to the current situation, scientists say it will take 2-300 years to transform Mars into a second earth, but it is better to do it than not to do it at all.

Many people don't understand why they want to go to Mars. Abandoned celestial bodies? Actually, there is no way out. If humans don't explore extraterrestrial planets, then when the earth's resources are exhausted and the ecological environment is irretrievably destroyed, there will definitely be competition, which is not a problem that anyone can control.

So if you have the skills and strength to open up a new world, why not? What's more, the whole world is calling for the protection of the earth's biosphere, and everyone can't make Qi Xin, Qi Xin and Qi Xin work together to make the earth's ecological environment worse and worse, which has already warned mankind, right? Friends forever? Only? Forever enemies? Same.

Therefore, space migration or future choice is also the only choice for human beings to maintain the earth without any cooperation from Qi Xin, otherwise people without strength will be annexed sooner or later. Therefore, if we want less competition, protect the earth and cherish everything on the earth, it is possible for human beings to reach a heart, but this possibility is not great.
