After entering the road of scientific and technological development, mankind soon realized the dream of flying to the sky, walked out of the earth and began to explore the universe. The most important task of exploring the universe is to find a new earth suitable for human survival. Maybe many people don’t understand why human beings choose a second planet to live on? Isn’t it better to live on earth?
But in fact, with the rapid development of human science and technology, the consumption of the earth’s resources is accelerating. In a few hundred years, mankind may face the risk of depletion of the earth’s resources. And the rapid development of science and technology has also exacerbated the deterioration of the earth’s ecological environment. Now the earth is dying step by step. It is possible that in the near future, the earth will not be suitable for human survival. At that time, we will have to leave the earth and go to other planets to live.
The purpose of human exploration and search for a new earth is for the future and continuation of human beings. Although scientists have been expecting to transform Mars into a suitable planet for human beings, the inherent conditions of Mars are not ideal for human beings to immigrate to the earth. The new earth that is really suitable for human survival can only be found outside the solar system. Although there are countless planets outside the solar system, and there are many planets that are believed to have life, the livable planet that human beings are looking for must meet the living conditions that human beings need, such as suitable temperature, suitable light, magnetic field similar to the earth, thick atmosphere, and the weight of the earth Almost.
Therefore, when scientists search for earth like planets in the galaxy, they focus on those earth like planets that are very similar to the earth, and hundreds of such planets have been found so far. Although we can observe earth like planets similar to the earth, we can’t really observe the specific data of the target planets. To get these data, we can only observe them in close range.
With the current science and technology of human beings, even the solar system can not go out, so naturally it will not be able to go to the planets tens of light years or hundreds of light years away for exploration. However, with the continuous development of human science and technology, it is possible that in the near future, human beings will be able to leave the solar system to explore nearby galaxies, or go to the earth like planets that have been found to be very similar to the earth for close-up survey, so as to determine whether they are suitable for human survival.
If one day, human beings have the ability of interstellar navigation and arrive at a planet that is very similar to the earth, and we find that there is life on this planet, how will human beings treat the life above? Many people may say that life in the universe may be very rare, and the new earth we are looking for may not necessarily have life.
But in fact, in the minds of scientists, the conditions for the existence of life on planets that are very similar to the earth are very high. It is possible that hundreds of earth like planets similar to the earth have been discovered by human beings, and different degrees of alien life have been born on them. Therefore, when scientists found planets very similar to the earth in the universe, they basically recognized that there would be life on them, but they didn’t know at what stage of the evolution of life.
If human beings find a livable planet in the future and have found life on the planet after arrival, how to treat the life on it mainly depends on the evolution stage of life on the planet. If it’s just a group of life without wisdom, they are similar to the animals on earth in the eyes of human beings. For most species that do not pose much threat to human survival, we will allow them to develop freely without destroying their biological chain system.
For some rare species, we will also protect them well. However, for beasts that can seriously threaten human survival, human attitude may not be so mild. For example, there are dinosaurs on the planet, such as the earth’s dominant dinosaurs 65 million years ago, which will pose a serious threat to the survival of human beings.
Although mankind is a scientific and technological civilization, with powerful science and technology, we are not afraid of big beasts like dinosaurs, but when we immigrate to the new earth, it is impossible to carry weapons with us when we go out of the wild. If there are no powerful weapons, once people encounter dinosaur level large beasts in the wild, the human weak body is not an opponent at all.
Therefore, once human beings discover the existence of life on the target planet, they will have different attitudes towards different kinds of animals. Most of the animals and plants without threat will be treated kindly, but if they are ferocious and unfriendly large beasts, they may start the extinction plan and make them disappear. Seeing this, many people may wonder whether the dinosaurs 65 million years ago were extinct in this way?
Although it is generally believed that the extinction of dinosaurs was caused by asteroid impact, some people think that the extinction of dinosaurs may have another reason. One of the reasons is that human beings are extinct. If so, the origin of human beings may be worth rethinking.
These are the ways to deal with life without wisdom. But if intelligent life has been found on the livable planet and civilization has been formed, the situation will be more complicated. Once a life grows into a civilized planet, we can occupy it again, that is aggression and colonization. It will inevitably lead to interstellar war. Some people may say that we can live peacefully on the same planet with alien civilizations.
I believe many people know that two tigers are not allowed in one mountain. If two different civilizations are born on one planet, it may be difficult for them to live in peace. Let alone civilizations from other planets, the probability of peaceful coexistence is extremely low. Imagine that an alien civilization will come to the earth tomorrow and say: we will settle down on the earth and let half of the earth’s territory out for them to live in. Will human beings agree? Of course not.
Therefore, once a livable planet is found to have civilization, there are only two choices for human beings. One is to launch an interstellar war to exterminate the alien civilization, so that human beings can completely occupy and colonize the planet. The other is to abandon the planet and look for another planet suitable for human survival. So what kind of treatment would humans choose?
It’s not so easy to choose the second one. Even if human beings can win in the end, the price will be huge. The goal of human beings is to find a new earth suitable for human beings. There are many such planets in the galaxy. Even if we give up one, we can still search for a second one. There is no need to spend time on a planet with wisdom and civilization.
Therefore, under normal circumstances, interstellar wars rarely occur between civilizations in the universe. If it is to occupy territory and resources, it is totally unnecessary. The universe is too big for us to imagine. If interstellar navigation is realized, we can explore a wider area. There is no shortage of habitable planets and resource planets. There is no need to fight for a planet and resources. Unless there are precious resources on this planet that both sides need, which are very rare in the universe.
Of course, interstellar migration is too far away for human beings. To achieve the slowest speed, we need to achieve sub light speed. To achieve this, it will take at least several hundred years. Although we are going to explore exoplanets, scientists have already begun to consider further issues, including the disposal of life on the discovered habitable planets.
Mankind is a civilization looking for peace. Even if it becomes a powerful interstellar civilization in the future, it can find many intelligent life planets. Ordinary life and intelligent life on the planet will be treated in a mild and peaceful way, rather than violence. The more powerful a civilization is, the more it needs to keep a low profile in the universe and know that a mountain is higher than a mountain.
