Only 20 light years from the ground! Gliese 58 1g planet, why do you think 100% is alive?

The earth, one of the eight planets in the universe, is the only known planet with life, which is unique in the universe. The earth was originally the cradle of human life, but with the increasingly serious ecological damage, the earth has long been overwhelmed.

As a result, some experts began to look for planets suitable for human habitation in the universe, the most famous of which is the "Mars Migration Plan". So, what is the probability that there are livable planets in the universe and the Milky Way?

As early as the 20th century, some experts boldly predicted that if there were more than 1000 billion stars in the Milky Way, there would be1000,000 Earths even if there was only one in ten thousand chance of an Earth-like planet. So, why do experts only find that the earth is suitable for human life so far?

In fact, we found many livable planets, such as Kepler 186F, Kepler 22B, Tiancang 5e, Tiancang 5F, and the magical gliese 58 1g planet. Gliese 58 1g is going to be popular today. Why is 100% alive?

Introduction of gliese 58 1g, why 100% is alive?

According to relevant data, a planet must meet the following conditions if it wants to satisfy human habitation. The first is internal conditions, suitable temperature, breathable atmosphere and liquid water. Followed by external conditions, stable illumination and stable stellar radiation. Safe orbit operation, large and small planets do not interfere with each other, and there will be no collision of small celestial bodies. Of course, these are just basic conditions. So, does gliese 58 1g meet these conditions? What kind of planet is it?

Gliese 58 1g is about 20.5 light years away from the earth. It was discovered as early as 20 10 years ago. After ten years' observation, it is concluded that gliese 58 1g is the most similar exoplanet to Earth so far. The diameter of Gliese 58 1g is about 1.2 to 1.4 times that of the earth, and its mass is about 3. 1 to 4.3 times that of the earth. Its average distance from the main star is less than100000 km.

In addition to the appearance features, the researchers also found that the average temperature of gliese 58 1g is between-12 and -3 1, and there is a great gravity on the planet, which can attract more atmosphere and has a certain degree of greenhouse effect. Stranger still, this planet is half day and half night. In this environment, if you want to live on this planet, the most suitable place is near the terminator line.

Astronomical experts believe that there is an atmosphere and liquid water on this planet, and some areas on the surface are suitable for life. According to the characteristics and habits of life, the probability of living in gliese 58 1g is close to 100%. As long as a single-celled organism or bacterium is found in gliese 58 1g, the uniqueness of life on earth will be shaken. So, did you find intelligent life in gliese 58 1g?

Did gliese 58 1g find intelligent life?

At present, gliese 58 1g has not found any traces of life, but it still has very important research value. What is the reason?

Because the conditions for the birth of intelligent life are very harsh, so far, we have not found traces of intelligent life on any planet. Even the livable planet found only meets two basic conditions. The first is a rocky planet with a hard surface and almost the same size and shape as the earth. Second, it is located in a livable zone, suitable for human habitation.

It can be seen that it is very difficult for a planet to give birth to life, even intelligent life. Take the earth as an example, there are several planetary guards around, each with his own duties. For example, Jupiter can block the wind and rain of the earth and attract the impact of small celestial bodies.

On the other hand, he disturbed the asteroid belt, causing countless ice cubes to hit the earth and ensuring the water supply of the earth. The earth also has a natural satellite-the moon, on which the ebb and flow of tides and the evolution of life depend. In addition, there are plate movements inside the earth. Violent earthquakes and volcanoes can release the energy inside the earth and keep the temperature of the earth within a suitable range.

In addition, even if a planet has life, it is not easy to have intelligent life. For example, bacteria and viruses have survived for hundreds of millions of years and still have no wisdom, which shows how difficult it is for intelligent life to emerge. Even if intelligent life does appear, it will take a long time to evolve to enter the era of science and technology. For example, the traces of aliens found on the earth now are all fictitious and have no scientific basis. Of course, it is hard for us to imagine the magic of unknown life, because aliens do not necessarily appear in the form of earthlings.

There is only one earth, and it is everyone's responsibility to protect it.

There is a classic saying in the movie The Wandering Earth. At first, no one cared about the disaster until it was closely related to everyone. With the development of the times, the destruction of nature by human beings is becoming more and more serious, and many natural creatures are affected, and the population is sharply reduced or even extinct.

There is only one earth, so it is urgent to protect it. Only when man and nature live in harmony can we human beings live on the earth for a long time. Because even if there are other planets suitable for human habitation, technology will not reach the level of immigration for the time being. Moreover, even if Griese 58 1g is really suitable for human habitation, will you go to a strange planet to live and develop?
