How to immigrate to gliese 58 1g

At present, human beings can't leave the earth, so they can only go to the moon for a while and then come back. The harsh space environment and limited scientific and technological level limit our pace and make it impossible to explore further.

At present, human beings confined to the earth only know that there is life on the earth in the universe. In our cognition, life on earth is unique, and so is human civilization. This uniqueness means that human beings are almost masters of the world, but it also makes most people feel lonely.

The universe is so big, but we can only follow the earth and float in a small corner of the galaxy. No matter how big the universe is, it doesn't make sense to us. In order to find the meaning of life, we began to explore the universe, want to find other life and even civilization in the universe, want to communicate with them and learn more knowledge.

Although human beings are trapped in the universe, we can still observe the universe in various ways, trying to find the secrets of the universe and the possibility of life from the vast xinghai.

Our protagonist Gliese 58 1g today is a planet that is likely to have life. Some scientists even think that there are absolutely protozoa on it.

More and more scientists believe that there must be other life in the universe, because there is life on earth. For science, any phenomenon is likely to reappear. Simply put, there is one and there are two. As long as life can be born on earth, it will be born on other planets with similar environment.

What's more, the space is too big, and there are countless planets and galaxies. Calling the earth a "unique" special existence is too blind and arrogant.

If we can accurately know the birth process of life, we can analyze the reasons for the birth of life and find qualified planets in the universe according to those reasons. But so far, we can't know exactly why life originated.

At first, scientists thought that life on earth was in the early stage of the formation of the earth. The ocean is heated by the high temperature of the earth's core into hot soup, and the amino acid molecules in the ocean change dramatically and rapidly at high temperature. In countless changes, amino acid molecules synthesized protein, and then these protein gathered together to form the first single-celled life.

However, in the process of exploring space, scientists often find complex amino acid molecules on celestial bodies such as asteroids or meteorites floating in the universe, and even some amino acid molecules are very close to the composition of protein.

Scientists believe that amino acids floating in the universe is probably a normal state, because amino acid macromolecules are actually the common product of many celestial bodies, so scientists believe that perhaps the amino acids that make up the first single-celled life on earth actually come from the universe, that is, the real source of life is actually other planets, and we are probably all aliens.

If amino acids floating in the universe can form life on earth, it will inevitably repeat the same thing on similar planets. In the universe, the number of planets like the earth is close to infinity. No matter how low the possibility of life is, it will inevitably reappear in the face of an infinite order of magnitude.

Moreover, because meteorites may contain complex amino acids, they may of course carry dormant living cells. Perhaps life forms are so common in the universe that their basic units can be seen everywhere in the universe. And we know that even the water bear worm, a life on earth, can survive in a dormant state in space for a long time.

In other words, life came directly to the earth and then began to evolve, which is not low, and it also means that life is a very common phenomenon in the universe.

Scientists believe that there are at least10 million planets in the Hubble volume with life. So with this simple expectation, mankind began to look for all the planets in the universe that might have life.

Life may exist in many ways. All life on earth belongs to carbon-based life, because the main element of life is organic matter transformed from carbon. But the universe is so big that any life form is possible. Perhaps gaseous life based on hydrogen and silicon-based life based on silicon can exist.

But human beings can't imagine and understand how those lives exist, so we can only look for planets with carbon-based life as our reference, because even if there are other life forms, we probably can't communicate with them, so of course we give priority to looking for carbon-based life.

Since we take ourselves as the reference object, of course, we should sum up the present situation of the earth:

The earth has a stable light source provided by the sun, and the solar wind of the sun blocks many extremely harmful cosmic rays for the earth, so we need a stable star to judge the existence of life;

(2) In the solar system, the earth belongs to the third planet, not far from the sun, so the temperature of the earth is more suitable for the reproduction of life. The distant planet has become a big ice cube, and the nearby planet has become a big stove. The existence of life depends very much on the stability of temperature.

Therefore, according to the position of the earth, scientists calculate the livable zone suitable for life around the stars, so we mainly look for planets that exist in the livable zone.

(3) In the solar system, in addition to the sun providing heat and protection for the earth, other planets also provide help for the emergence of life on the earth, the most important of which is Jupiter, which captures most asteroids entering the solar system with strong gravity and often oscillates, throwing ice asteroids in the asteroid belt into the solar system, providing sufficient water resources for the earth.

(4) The size of the earth. The size of the earth should not be too big. If it is too big, its gravity will crush all life and capture a large number of asteroids similar to Jupiter. In this case, there can be no life on the earth. If the volume is too small, then the earth will not be able to attract the atmosphere, and the surface of the earth will be like the moon, with only a vacuum.

With these conditions, scientists began to look for planets in the livable zone of star life in all single-star systems, and the quality of this planet must be not much different from that of the earth.

Up to today, scientists have discovered more than 30 eligible planets, among which gliese 58 1g is the planet that scientists think is most likely to have life, also known as super earth.

Gliese 58 1g is the sixth planet in gliese's 58 1 galaxy, with a diameter of 1.2 to 1.4 times that of the earth, a mass of 3./kloc-0 to 4.3 times that of the earth, and a distance of 58 1 from gliese.

Knowledgeable readers should know that the distance between the earth and the sun is actually1.500 million kilometers, which is five times that of gliese (58 1g). Then why do scientists still think that gliese's 58 1g will have life?

In fact, it is because the star of gliese 58 1 galaxy is a red dwarf, which is darker and colder than the yellow dwarf of the sun. Therefore, according to the change of star conditions, the livable zone of stars will also change.

It is about 20.5 light years away from the earth. It will take 350,000 years to get to gliese 58 1g by Voyager I, the fastest aircraft.

If we only look at the conditions of the planets, it is indeed possible for gliese 58 1g to give birth to life. First of all, its location belongs to the livable zone of life, which means that its temperature will not be too high or too low, and it can also be protected by stars.

Then it is about the same size as the earth, and its mass is about three times larger than the earth, which means that its gravity will be larger than the earth, but not much larger. In such a gravity environment, its atmosphere will be highly similar to that of the earth.

According to the observation of scientists, gliese 58 1g is a planet surrounded by the star tidal locking.

The so-called tidal locking is actually the same as the relationship between the earth and the moon. The moon is firmly bound by the gravity of the earth, which makes it unable to rotate, so it can only revolve around the earth under the gravity of the earth. Therefore, the moon always faces the earth on one side, and the moon turns itself every time it turns.

Gliese 58 1g is in the same state as a star, so it will not change between day and night. One side of Gliese 581g is always in the day and the other side is always in the night. In addition, tidal locking also keeps gliese 58 1g unchanged.

According to observation and calculation, scientists believe that gliese 58 1g is likely to have an atmosphere, and its atmospheric composition should be very similar to that of the earth, so it is likely to have carbon dioxide, and then it will have a certain greenhouse effect. Under the protection of carbon dioxide, the average temperature of 58 1g in gliese is likely to be between minus 37 degrees and minus 12 degrees.

Coupled with its eternal day and night, the temperature in the daytime will be higher, on the contrary, the temperature in the back will be lower, so there will inevitably be a zone with suitable temperature at the junction of day and night, which will probably give birth to life.

The gravity of gliese 58 1g is likely to form the atmosphere. If the atmosphere is dense enough, when the atmosphere flows, the heat in front will be carried to the back, so there will be a thermal balance in gliese 581g. In other words, it may not be limited to the place where day and night meet, and the whole planet may maintain a more suitable temperature.

In the past, when scientists were looking for habitable planets, they could only find suitable planets in star systems tens of billions of light years away. However, with the development of science and technology, livable planets closer to us have been gradually discovered, which means that there are not a few planets similar to the earth in the universe.

So scientists put forward the possibility of livable planets and recalculated that there may be billions of livable planets in the Milky Way. The possibility of life will be greatly enhanced.

At present, our scientific and technological level is not enough to fully obtain the information of planets 2 billion light years away, and scientists can't assert that there must be atmosphere or even life on gliese 58 1g, but with the development of our science and technology, we can definitely see the true face of gliese 58 1g, and even go there to explore the existence of life.

With the exploration of the universe, the possibility of life in the universe is increasing. We believe that we will encounter extraterrestrial life and even extraterrestrial civilization in the future. At this time, we will face a problem-how to communicate with extraterrestrial life.

The famous science fiction novel Three-body once described the cosmic environment of a dark forest. Because communication in the universe is too difficult, all civilizations can only choose to go to war with other civilizations, and the universe is a huge battlefield.

However, the reality does not necessarily develop as described in the novel. For example, most people are curious and friendly when we treat alien civilizations. We don't need to attack an alien civilization that can prove that we are not alone.

However, the probability of life only appearing in the universe is too low to be discovered, and the evolution of civilized life is a low probability event. Viruses and bacteria have existed since the emergence of life. They have evolved for three billion years. Civilization is not the only evolutionary direction of life, so if we can find a planet that has also evolved civilization, maybe there will only be feelings of mutual appreciation between them.
