The earth is the homeland where mankind has lived for millions of years. In this big home, each of us has our own small home, which is what we commonly call the house. So can our house exist forever? I believe that every friend knows that a house cannot exist forever. Even if it is not demolished after it is old, it will disappear completely someday in the future. This is the power of time.
Since a small home like a house cannot exist forever, can a large home like the earth exist forever? In fact, it is difficult for us to give a definite answer to this question. In theory, whether it is a star or a planet, there will be an end. The sun is a star, but its life span is only 10 billion years. After another 5 billion years, it will reach the end of its life and transform into a white dwarf.
It may be said that when the earth will come to an end, that is determined by the sun. When the sun reaches the end of life, the earth will no longer exist. If the earth is an ordinary planet, then the fate of the future is to be swallowed by the expanding sun. I believe everyone knows that before the sun goes to its end, it will first expand into a red giant, and the expanding red giant will swallow Mars, Venus, and finally the earth.
This shows that under normal circumstances, the earth cannot see the day when the sun turns into a white dwarf, and it will be swallowed by the expanding sun very early. Is the ultimate fate of the earth really like this? We said earlier that if the sun is an ordinary planet, its ultimate destiny is to be swallowed by the sun, but is the earth an ordinary planet? of course not.
The current earth is a planet of wisdom and civilization, with human beings who have entered the age of science and technology as the hegemon. And the ultimate fate of a civilized planet may not be passive, but will become active, which is determined by the intelligent civilization on this planet. The ultimate fate of the earth may also be determined by human beings. Whether the earth will end, when it will come to an end, time is determined by mankind.
Many people may not understand this. How does humanity decide when the earth will come to an end? I believe my friends will understand that when viewed from space, the earth is actually a floating ball in constant motion. From the perspective of the universe, the earth is as small as a grain of dust. And this dust has its own orbit, and it moves around the tiny sun.
So how did this orbit of the earth come from? In fact, it is a function of universal gravitation. So can this universal gravitation be changed? The answer is yes. The reason why the earth’s orbit is stable is that gravity has reached a balance. If an external force changes this balance, then the earth’s orbit will also change, even out of the constraints of the sun’s gravity.
If the earth cannot break away from the sun’s gravitational bondage, it will be swallowed and disappeared by the expanding sun for billions of years. To change the destiny of the earth, we only need to get rid of the sun’s gravitational bondage, and to do this, we need to rely on the power of science and technology.
Technology is to constantly crack the mysteries of everything and the mysteries of the universe. As long as the strength of science and technology reaches a certain level, the trajectory of celestial bodies can be changed. Billions of years are enough time for mankind to develop technology to a high level. At that time, we may not have the ability to change the universe, but it may not be difficult to change a small solar system.
Even if it cannot completely change the destiny of the sun, it is a trivial matter to change the destiny of an earth. We can completely modify the earth to make it a planet that can move and wander autonomously, so that it is farther away from the sun, so that it will not be swallowed by the sun. When the sun’s life ends, we can move the sun directly out of the solar system to other galaxies.
With the help of human science and technology, the destiny of the earth may be completely changed, and there is basically no cosmic disaster that can threaten a wandering planet. We can avoid the sun’s expansion and swallow, and we can also avoid the impact of celestial bodies. Even if we don’t want to wander, we can also place the earth in a stable star system and orbit the stars.
This shows that the future destiny of the earth is closely tied to mankind. As long as human civilization does not end, the earth will not usher in the end. With the assistance of human science and technology, it can always exist. Other stars and planets continue to destroy and disappear, while the earth will become more and more ancient. Even if the universe will come to an end in the future, and when human technology develops to the ultimate point, it may be possible to ignore the end of the universe.
Human beings detach from the universe, so the earth can also follow the detachment from the universe and become an eternal existence. Human beings were born on the earth. Mother Earth gave birth to us and provided us with a stable and suitable environment for us to continue to grow. This is the contribution of Mother Earth.
When human beings truly grow up, we must continue to help Mother Earth, get rid of the shackles of various disasters, and let the planet exist forever. Now, we are proud of the earth, and the earth will be proud of mankind in the future. Perhaps in countless years, mankind will be exposed to various cosmic civilizations. The strength of mankind will continue to develop and grow, and Mother Earth is the best witness.
Of course, we have not really grown up yet, and we are not yet a powerful interstellar civilization. And human beings also need to rely on Mother Earth for shelter. We cannot survive without the Earth, so the Earth is very important to human beings now. The development of science and technology needs to be completed step by step, and it takes a long time.
However, at the same time that human beings are rapidly developing science and technology, they have neglected the protection of the earth’s ecology and continue to destroy the earth’s environment. If the earth’s environment deteriorates rapidly and becomes unsuitable for human survival, human beings have not yet become a powerful interstellar civilization, and they have not yet been able to survive without the earth. At that time, human civilization may come to an end.
If human civilization ends and disappears, then the ultimate destiny of the earth will not be changed, and it will be swallowed by the sun billions of years later. This shows that if mankind wants to change the ultimate destiny of the earth, we must first take care of the earth’s environment, so that the earth has enough time to protect the development of mankind.
If we continue to destroy the earth, in fact, we are constantly ending the future of mankind. One day, we will suffer the consequences for ourselves. Therefore, all mankind should take action and put the protection of the earth’s ecology first. Only when everyone has an awareness of environmental protection will our earth be more beautiful and the future of mankind Better.
