There is a space outside the solar system with thousands of comets, with a total mass of 100 earths

The earth is a beautiful planet of life, and the birth of mankind has also upgraded this planet of life to a civilized planet. After entering the era of science and technology, human beings began to explore the mystery of the earth and the origin of life on the earth.

So how did early life on earth come about? We should know that there are eight planets in the solar system. At present, only the earth is found to be a beautiful planet of life, and the species are very rich. Why has the earth become such a beautiful and extraordinary planet of life? There must be reasons for this. The birth of life needs to meet some conditions. First of all, it must be in a livable zone and be able to get the suitable temperature and light of the sun. Second, it must have a thick atmosphere. The most important thing is to have rich liquid water resources.

Through research, scientists have found that the early life of the earth originated from the ocean, and most of the material of the earth’s life, including the human body, is actually water. For example, 70% of the material in the human body is water. It can be seen that water is the source of life. Without water, there will be no birth of life on the earth, let alone human beings. So how did the water of the early Earth come from?

You know, the earth was formed 4.6 billion years ago. At that time, there was not a drop of water on the earth. Moreover, the earth was close to the sun, and it was unlikely that there were water molecules in the surrounding space. Therefore, scientists speculate that the water in the early stage of the earth came from the impact of comets. Comets brought abundant water resources to the earth, which gave the earth the source of life.

The birth of life on earth and the appearance of human beings should be thanks to comets. Without comets, there would be no beautiful earth with various kinds of life. So where did these comets come from? There are no comets in the inner galaxies of the solar system. Some people once thought that these comets came from the Kuiper belt on the edge of the solar system. But don’t forget, the formation of the Kuiper belt is later than that of the major planets. It is actually a ring belt formed by the solar wind blowing the dust and other matter of the inner galaxy to the edge of the solar system.

Therefore, the comets that hit the earth in the early stage could not have come from the Kuiper belt, which did not form at that time. These comets can only come from far beyond the Kuiper belt, which scientists once thought was interstellar space outside the solar system, but later through observation and research, it was found that this was not the case.

You know, the number of comets entering the inner Galaxy in the early solar system was not one or two, but a lot. Many ice covered moons of Jupiter and Saturn may be comets that came to the solar system at that time, and they were finally attracted by the strong gravity of Jupiter and Saturn and became comets. Some comets also hit Jupiter and Saturn, hitting earth, Mars and Mars.

It can be seen that the number of comets entering the galaxies in the early solar system is very large, so many comets are unlikely to come from the interstellar space outside the solar system. So scientists speculate that there is a special space outside the solar system, where there are thousands of comets with a total mass of 100 earths.

I believe many friends have thought of what this special space is. Yes, it is what we often call the Oort nebula. The Oort Nebula existed long before the birth of the solar system. It is actually the birthplace of the sun and the solar system. Now science on the origin of stars, it is believed that it starts from the center of the nebula, the matter in the nebula continues to agglomerate and finally form a star.

The birth of the sun is almost the same. Five billion years ago, the central material of the Oort Nebula began to condense and form the original celestial body. The mass of the celestial body grew, and finally condensed most of the material of the Oort nebula. Finally, it ignited the internal nuclear fusion and evolved into a stellar sun. After the formation of the sun, the residual material formed eight planets, the sun and the eight planets did not consume all the material in the Oort nebula.

After the formation of the sun and planets, the remnant of the nebula left in the periphery of the solar system and surrounded the solar system, forming the structure that the Oort Nebula surrounded the solar system. In fact, this kind of structure is not uncommon in the universe. Scientists have also observed many similar nebulae through astronomical telescopes. There are stars shining in the center of these galaxies, indicating that there is a star there. Where there is a star, there is probably a galaxy.

The Oort Nebula covers a very wide area, with a diameter of 2 light-years. Although it is very wide, its internal material density distribution is very large. Although it is not as rare as the interstellar space outside the solar system, it is much wider than the material density of galaxies inside the sun. In the vast Oort cloud, scientists speculate that there will be at least 1000 comets. Besides comets, there will be other celestial bodies and dust.

The Oort cloud is a concentration of comets. It takes thousands of years for some comets to reach the sun from there, such as the famous chiguguan comet, but some long-period comets may take millions of years. However, there may also be some objects with larger size and mass in the Oort cloud, such as the asteroid Sedna, which is considered to belong to the inner layer of the Oort cloud. Scientists suspect that the ninth largest planet in the Oort cloud may also belong to the Oort cloud, which takes 10000 or 20000 years to orbit the sun.

Because the Oort nebula is far away from us, it is not realistic to send a detector to detect it with the current human technology. In fact, voyager-1, the fastest and farthest human spacecraft, has passed the Kuiper belt and is now heading towards the inner edge of the Oort cloud. It will enter the Oort cloud in about 530 years, and it may take at least 10000 years to cross the entire Oort cloud.

The Oort nebula is one of the most mysterious regions in the solar system. At present, we can only make fuzzy observation and analysis through astronomical telescopes. We believe that in the near future, with the rapid progress of human science and technology, and with faster spacecraft, we can fly to catch up with Voyager 1, enter the inside of the Oort cloud in advance to explore and uncover the mystery of comets there. It is possible that we will find out the real secrets of the solar system there, even the mystery of the origin of life on earth.
