After 5 billion years, both the sun and the earth may perish, so what is the significance of human efforts?

Everything in the universe seems to obey such a law: if there is life, there must be death, whether it is conscious life or unconscious stone; No matter it is as small as an atom or a huge celestial body like the earth, it cannot violate this law. Speaking of which, some people object. You say that atoms, life and even stones will die, and they all agree, but you don't understand that the earth will die, too. It seems that no force in the world can destroy the earth. Unless there is a divine civilization in the universe, such an advanced civilization can destroy the earth. Although what they say is very reasonable, there is another force in the universe that can destroy the earth besides the sacred civilization. This is the sun. Why do you say that the sun will destroy the earth?

The sun has burned for 5 billion years, and it will burn for another 5 billion years.

Because scientists found that the sun is a star, and stars actually have a life span. The life span of a star is about 654.38+00 billion years. Now the sun has been burning for 5 billion years. In its prime, the sun will die in five billion years. When the sun dies, it will form a red dwarf star. When the sun forms a red dwarf giant, its volume and gravity will expand rapidly, and eventually it will devour the earth. Buried with him? In other words, without asteroid impact, nuclear war and climate warming, the earth will perish one day in the future. Since human beings know that the earth will die one day, why should they work so hard to develop their own civilization?

Evolution process of solar stars

Although mankind knows that the earth will perish, it is still a long time before it dies. We say that even if there is only one second left, we can't give up, not to mention that human beings still have 5 billion years. What can you do if you don't work hard for so long? Dazed? Give up on yourself? Is there a war? No, mankind still has a lot to do. They want to pursue a better life and conquer the solar system, the Milky Way and even the whole universe. With so many ideals to be realized, how can they think of the ends of the earth? Just like a person can only live to 100 years old, when he understands the truth of life at 18 years old, he knows that he will die at 100 years old in the future. Has he been thinking about this problem for the next 80 years? I'm going to die anyway. Why bother? This is completely wrong. A person's efforts are not only for himself, but for his family, children, hometown and friends. If it's just for yourself, then it's really meaningless to work hard, because you don't know what you need at all.

When the sun becomes a red giant, it will devour other planets in the solar system, including the earth.

In the same way, human efforts are also for the earth, for future generations and for a better life. And history also shows that as long as we work hard, we can live a higher quality of life, such as all kinds of delicious food, high-quality medical care, palaces and trips that only emperors can enjoy in ancient times. Now ordinary people can enjoy it, and the quality of life of ordinary people is even higher than that of ancient emperors. This is the meaning of human efforts. This will happen if we don't work hard. Of course, human efforts have another meaning, that is, to improve the level of human civilization and find a new home for the earth in the universe before it is swallowed up by the sun. As long as mankind finds a new home in the universe, it will not perish after 5 billion years, and even realize the dream of conquering the universe.

Human efforts are to prevent the earth from destroying me.

Therefore, as long as it is not until the last moment, we will definitely not give up our efforts. Even if we know that tomorrow is the end of the world, today, human beings will try their best to continue human civilization. This is a mission and responsibility, and it is a spontaneous quality in human genes. It is impossible for human beings to do other things against their will, especially at the moment when life and death test human nature. People are dying, and you still say good things? .

For the future of mankind, mankind is still working hard. The picture shows the rover.

In fact, 5 billion years is enough time for human beings to realize interstellar migration, so human beings still have to work hard. If we stop working now, mankind will have disappeared from the earth before it is destroyed. Scared to death? Worrying too much can make people hard. If they work hard, they will lose confidence in life and they may act irrationally. Therefore, efforts have another function, that is, they can eliminate all kinds of worries and make people regain their confidence in life.
