In interstellar exploration, if humans find a habitable planet, will they destroy the indigenous creatures on it?

When human beings walk out of the earth and see the vast universe, they have a dream that they can find more livable planets, and let human steps spread all over the galaxy and even the universe.

There are countless galaxies and planets in the vast universe. Naturally, we can’t search aimlessly, so that human beings may never find a livable planet. The universe is too big for us to imagine. Therefore, to search for habitable planets, human beings need to work out a set of standards to narrow the search scope.

Since human beings have not found a second life planet after going out of the earth, and we don’t know what kind of planet alien life lives on, we can only use the earth as a model to formulate the search criteria.

Scientists believe that since the universe has endowed the earth with the attributes of life, the characteristics of the earth itself and the characteristics of the solar system where it is located must also be very conducive to the birth of life. It is very scientific and reasonable to develop a livable model based on the various factors contained in the earth. After the development of this livable model, when human beings search for livable planets, the scope will be greatly reduced.

This livable model mainly includes six factors: the main star is similar to the sun, located in the livable zone, just right away from the star, the planet itself has an atmosphere and magnetic field, there is a giant planet on the outside, and there is a large satellite nearby.

The above six factors are the key to the earth becoming a planet of life and eventually evolving into human beings. For example, the main star should preferably be a yellow dwarf star similar to the sun, which has a long life, is relatively stable, and has moderate radiation energy, and can provide suitable light and heat for stars in the habitable zone.

Through this condition, we can greatly narrow the search scope. We need to know that there are at least hundreds of billions of stars in the Milky Way alone. If we search all of them, it will take a long time, and there will not be any harvest. However, with the establishment of the standard for yellow dwarfs, the scope of search will be greatly reduced.

You know, there are so many stars in the universe that you can’t count them. In the whole star family, yellow dwarfs are only a few, but there are more massive stars. Therefore, when we search for habitable planets, we can completely ignore other stars and focus on yellow dwarfs.

Scientists in the search for extrasolar habitable planet plan, according to the earth’s standard custom-made a similarity index, or ESI. If the ESI index of a planet is very close to 1, it means that it is more similar to the earth. On the contrary, the farther away it is from 1, the less similar it is to the earth.

In the solar system, Mars has the highest ESI index, reaching 0.73. It is precisely because of the high similarity between Mars and the earth that scientists have spent more energy on exploring and studying Mars in the past half century. Mars is also the second home expected by human beings, but it is not a natural and livable planet. It needs a series of modifications in the future to become the second earth.

Through the habitable model of the earth developed by scientists and the continuous search of astronomical telescopes, some planets with high ESI index have been found. Among them, one star named tegarden B has an ESI index of 0.95, which is very similar to the earth and is almost a copy of the earth.

The discovery of an exoplanet so similar to the earth is naturally a very happy thing. However, as the planet is about 12 light-years away from the earth, human beings have no ability to explore it at present. For the current human science and technology, the distance of one light-year is also a natural moat, which cannot be crossed. At the current speed of human aircraft, it will take about 20000 light years to complete the distance of one light year, and 12 light years is 240000 years.

Of course, with the continuous progress of human science and technology, once scientists turn the curvature engine theory into reality in the future, the space jump can be realized. At that time, 12 light-years was only a very short distance, which could be reached in a short time.

When humans have the ability to navigate across the stars, the Milky way will become our back garden for free exploration. When we become an interstellar civilization, we will find many livable planets, most of which may be very suitable for human survival, even more beautiful than the earth.

However, when we find a large number of livable planets, we will also find that there is a high probability of life on these planets, even the existence of intelligent civilization. If a planet already has intelligent civilization, then if human beings want to occupy it for themselves and realize migration, there is a high probability that there will be conflicts and wars with the indigenous people on the planet.

So a question arises: if human beings find a habitable planet, will they destroy the indigenous creatures on it? Maybe some friends will say that mankind is a peace loving civilization. Since this planet already has intelligent civilization, we will automatically leave to find the next livable planet. There is no need to fight for this planet.

If you think so, it’s too idealistic and too simple. When Columbus discovered the new world, he also saw that there was a master on it. Did Columbus leave? Of course not. I believe my friends all know that it was a cruel fight.

Human beings and alien civilization are two different intelligent races. Naturally, human beings do not have the noble quality of peace in their hearts. Facing the alien aborigines, human beings are more concerned about the future of human civilization. Although the universe is vast and there are countless livable planets, to realize the free exploration of the universe, we need to develop science and technology to the ultimate.

For humans who have just become an interstellar civilization, the area we can explore is also very limited. In this area, it is very difficult to find a livable planet suitable for human survival. Now that we find one, will we give up? Of course not.

We need to know that the environment of the earth is becoming more and more unsuitable for human survival, and we urgently need a new livable planet. Once such a planet is discovered by us, no matter how difficult it is, we will take it, occupy the planet and become a new home for human beings.

And if we want to completely occupy a planet, will the native alien civilization agree? Obviously not. For the sake of the future and continuation of mankind, even if we can’t bear it, we have to carry out the action of extinction and wipe out all the aborigines on this planet. This is the cruelty between the civilizations in the universe. Hawking warned many times: let human beings not try to contact with alien civilizations, because it is a very dangerous thing.

Once the alien civilization finds out that the earth is suitable for their survival, it is highly likely that it will occupy the earth and immigrate. Naturally, human beings will not give up the earth, and the alien civilization will also understand this. Therefore, the outbreak of civilization war, with the strength of human beings, it is impossible to beat a powerful interstellar civilization, and finally it can only be brought to an end with unwillingness.

Therefore, once mankind becomes an interstellar civilization and goes out of the solar system, it means that the road of human colonization will be opened. On the way to colonization, it has never been so smooth. It is bound to be accompanied by all kinds of struggles, and wars between civilizations are inevitable. It may be a common practice for interstellar civilization to wipe out life on other planets. It has been speculated that the extinction of dinosaurs 65 million years ago may also be related to alien civilization, but there is still no evidence.
