Human beings have survived on the earth for millions of years, human science and technology is also constantly progressing, especially after the beginning of the industrial revolution, human beings have really embarked on the fast track, the speed of scientific and technological development beyond people's imagination, only took a short period of time but a hundred years or so to achieve the pace of going out of the earth and initially exploring the universe.
When human beings began to explore the universe and found that the universe was really too big, and the earth was just a grain of dust in the universe, people couldn't help but wonder: Is there any other extraterrestrial intelligent life in the universe? If we can find planets like Earth, does that mean that there is a high probability that this planet will also have extraterrestrial life or even intelligent life?
Therefore, human beings began to look for the existence of terrestrial planets in the universe through astronomical telescopes, the efforts of scientists, through the astronomical telescopes have really found a lot of terrestrial planets, but these terrestrial planets and the earth are not particularly similar, we want to look for and the earth similarity can reach more than 80% of the planet, at least to have liquid water and atmosphere.
Recently, when scientists observe the universe, they have found an Earth-like planet, which is very similar to the earth, and it is also a blue planet, which shows that there is a large amount of liquid water on this planet, and the volume of this planet is 1.6 times that of the earth, and the mass is almost 1.6 times that of the earth, which also shows that its gravity is about 1.6 times higher than the earth.
Scientists through the astronomical telescope to observe the star system of this Earth-like planet, found that it is located in a red dwarf star formed in the star system, and it is relatively close to the main star, the distance is relatively close, there can be a large amount of liquid water, indicating that the planet will most likely have a thick atmosphere, or enlarged version of the Earth.
When scientists are looking for extraterrestrial life, liquid water is a very important reference indicator, in our view, water is the source of life, we look for life in the universe, we will inevitably use the earth as a template and conditions to find, although the planet with life in the universe may be very different from the earth's environment, and even we think of a very extreme environment. However, planets that are very close to the Earth's environment may have greater life, and this is also an important condition for human beings to find suitable for our future migration.
This Earth-like planet is 201 light-years away from Earth, this distance is still a distant place for humans today, and we do not have the ability to reach a planet to explore now, but this planet has liquid water, an atmosphere, and may also have a magnetic field, which is too similar to Earth, in addition to being 1.6 times larger than Earth, other conditions that fully meet the conditions for human beings to find suitable for migration.
Of course, in the future, if you have the ability to reach this planet, whether you can immigrate or not you still have to consider a lot of conditions, one condition is whether there is intelligent life on it, if there is no intelligent life, it is okay, if intelligent life has been born or even the formation of civilization, it will have a great impact on the migration plan of mankind.
Scientists through observation found that the newly discovered Earth-like planet is 1 billion years older than the earth, that is to say, it is 1 billion years earlier than the earth, it is possible that the star system it is in is also older than the solar system, a life planet 1 billion years older than the age of the earth, if the above was born very early intelligent life, even if it is only 10,000 years earlier than the birth of humans, then their degree of scientific and technological development is also unimaginable, at that time, human beings do not expect to be able to immigrate, Instead, it is necessary to worry about whether it will be counter-invaded by the other side.
Another condition is the composition of the atmosphere on an Earth-like planet, humans exhale gas with oxygen, but not all planets with atmospheres will have oxygen, and the proportion of oxygen required by humans to breathe cannot be too large, nor too little, too big for humans to bear, too small for large categories to breathe. If the oxygen content of the atmosphere on this planet is exactly in line with the needs of human beings, then migration is not much of a problem, if there is no oxygen on it, the life on it does not live on oxygen, it is based on other gases as breathing gas, then it is basically impossible for humans to immigrate, unless artificially change the atmospheric composition, the atmospheric composition changes, if there is a lot of life on this planet, it will usher in a biological mass extinction, whether humans will do this is also unknown.
Finally, there is the problem of gravity, because this Earth-like planet is 1.6 times larger than the earth, then the gravity above it may also be about 1.6 times larger than the earth, if the other conditions of the planet are satisfied with the survival of human beings, we still have to adapt to its huge gravity, this gravity human just landed on this planet is certainly not adaptable, you will feel that you carry a weight heavier than your weight with each step.
But people's adaptability is still relatively strong, although gravity is very large, but humans can also slowly adapt, and in this planet for a long time, the human body will also have some evolution, such as the size will become shorter, the bones will become stronger, and the human physique will have a major improvement.
The above is just people's advance conjecture, what is the situation on this newly discovered terrestrial planet, whether there will be life and intelligent life, we do not know, this only when the future human spacecraft can exceed the speed of light, we can go to this terrestrial planet for detailed field investigation, if the living conditions of human beings are met and there is no existence of intelligent life, then human beings can immigrate with confidence, and we look forward to the arrival of this day.
