Scientists have found that the earth is moving away from the sun step by step. Is this a good thing or a bad thing?

The earth is the home of human survival, and the solar system is the home of the earth. Therefore, any change in the solar system may bring unknown disasters and risks to the earth and human beings. With the help of science and technology, human beings began to explore and study everything in the solar system, especially the laws of celestial bodies in the solar system.

For human beings, only if the solar system is stable enough and the external environment is safe enough, can human survival and development continue. Before human beings become a powerful interstellar civilization, any wind and grass outside the earth may bring us great disasters, such as asteroid impact, powerful solar storm and so on.

The sun is the largest star in the solar system. It is located in the center of the solar system. It is a star whose mass accounts for 99.86% of the total mass of the whole solar system. It is precisely because of the great mass of the sun that it has a strong gravity, which can bind the eight planets around it. At the same time, it also brings a safe and stable environment to the solar system. Normally, as long as there is no major change in the sun, there will be no major events in the solar system and the earth will be safe.

The sun is so important to the survival of human beings that naturally it has become a key research target of scientists. However, due to the strong gravity of the sun and the fact that it is a celestial body constantly emitting high-temperature energy radiation, we can only detect the sun from a distance, but not close to it. When scientists study and explore the sun and planets, they find a problem: the earth is moving away from the sun step by step. What’s the matter? Is it a good thing or a bad thing?

Scientists have found that the earth is moving away at a distance of about 1.5-3.5 cm every year. Although the distance is very small, after a long time, the distance is also a relatively large number. Why does the earth step by step away from the sun? Scientists have found that it is mainly related to the continuous loss of the sun’s mass.

We all know that hydrogen helium fusion is carried out inside the sun. When two hydrogen atoms converge into one helium atom, part of the mass will be lost. According to careful calculations, scientists found that the sun will lose about 4 million tons of mass per second.

Although it is a huge number for us to lose 4 million tons of mass per second, the mass of the sun is not even a drop in the bucket. If the mass of the sun is lost for a long time, its gravity will be affected. As we all know, the magnitude of gravity is directly proportional to the mass. As the mass decreases, so will the gravity.

Some people may worry: with the continuous loss of mass and the weakening of gravity of the sun, will one day lose the shackles of the eight planets? In fact, there is no need to worry about this. The mass of the sun accounts for 99.86% of the total mass of the solar system. Even if it loses more mass, it will not lose its gravitational control over the solar system.

Although the continuous loss of the sun’s mass will not lose its control over the solar system, its decreasing gravity will still affect the orbit of celestial bodies. Scientists have calculated that in the past 4.6 billion years, the mass of the sun lost through nuclear fusion is equivalent to the mass of 46 earths. To explore this effect, scientists launched a probe designed to measure the movement of mercury, the closest to the sun. The results show that in the four-year exploration process, the orbit of Mercury will increase with the decrease of the mass of the sun every year, which indicates that Mercury is also a little away from the sun.

Mercury is constantly away from the sun, and so is earth and other planets. However, the distance of the earth from the sun seems to be larger than that of other planets, which is related to the fact that the earth is a living planet and human activities. The earth is a living planet, the survival and development of life will consume energy and resources, especially after the birth of human beings, the consumption of earth resources is huge.

Therefore, the material on the earth is constantly being consumed and lost. In addition to the consumption of life and human resources, long-term weathering, erosion and meteorite impact will take away the earth’s material step by step. Therefore, the earth’s mass is actually getting smaller and smaller. When the earth’s mass becomes smaller, its gravity will naturally weaken. In this case, the overall gravity system of the sun earth system will continue to weaken and reduce, and the earth will naturally move away from the sun step by step.

The reason why the earth is far away from the sun has been found. Is this good or bad for the earth? If it is a planet without wisdom and civilization, when it is a little bit away from the main star, the temperature of the planet will be lower and lower, which is very unfavorable for the breeding and development of life, and may lead to the end of life evolution.

But for a civilized planet like the earth, it may not be a bad thing, but a good thing. Why do you say that? I believe friends all know that the earth’s ecological environment is getting worse step by step after mankind has entered the era of Industrial Science and technology. A lot of carbon dioxide and other greenhouse gas emissions make the earth’s temperature rising.

The impact of the rising temperature of the earth is huge, and natural disasters will continue to increase. And we have no good way to deal with this deteriorating ecological environment and rising temperature. It has been suggested that if the activity of sunspots can be weakened and the earth enters the little ice age, it can effectively cool the earth and let the earth’s temperature return to normal.

The earth entering the little ice age is certainly a very good cooling method. In fact, the earth’s constant distance from the sun is also a natural cooling measure. As long as the earth is farther and farther away from the sun, the heat received will be reduced and the natural temperature will be reduced. Nature can also weaken the greenhouse effect of the earth and balance the temperature of the earth. It’s a good thing for the earth to keep away from the sun.

Of course, this kind of situation is effective when the sun has not started to expand. If the sun is about to transform to a red giant in billions of years, although the earth may have been far away from the sun at that time, the speed of transformation and expansion to a red giant at the end of the sun’s life is far faster than that of the earth far away from the sun. At that time, the speed of mercury and Venus will increase The orbit is engulfed, and the orbit of the sun is close to the orbit of the earth.

When the sun changes to a red giant, the position of the earth will not be safe, and the temperature of the earth will rise sharply, even higher than the surface temperature of Venus. If human beings want to survive, they have to leave the earth and immigrate to other planets. Of course, billions of years later, if mankind can continue to develop, it may have become a powerful interstellar civilization.

For an interstellar civilization, colonized planets have already spread all over the galaxy and even other galaxies. If the earth can’t survive, it can migrate the earth’s residents to other galaxies and even pack the earth together. This is not a problem at all for an interstellar civilization.
