Before human beings walked out of the earth, although people were imagining that there should be a broader world outside the earth, we do not know how huge that world is due to the limitations of observation technology. Some people even think that the earth is The real big world, the sun, moon and stars in the sky are only part of the earth.
With the continuous progress of human civilization, we embarked on the path of technological development hundreds of years ago. With the help of technology, the astronomical telescope was invented. At this time, we initially saw the vast universe through the earth. Later, when human beings walked out of the earth, they saw for the first time what the real earth looks like from the universe, and also saw the solar system for the first time.
The solar system is actually a star system, composed of a central star, the sun, eight planets, and a large number of asteroids and other celestial bodies. With the continuous improvement of human observation technology, we have seen the outer starry sky. There is originally a Milky Way outside the solar system. It is a galaxy with a diameter of 100,000 light years. There is a massive black hole in the center. Hundreds of millions of stars move around this galactic center.
Our sun is only one of the stars. It is not a special star. The solar system is also an ordinary star system, but it breeds a blue planet with life, so it appears that the solar system has some extraordinary features. .
After leaving the earth, human beings have been searching for the existence of extraterrestrial life and extraterrestrial civilization. But after more than half a century of hard work, until now we have not discovered the existence of any extraterrestrial life, nor have we discovered a second planet of life. The unique and beautiful appearance of the earth shows the huge difference between it and other planets. This may be the unique demeanor of the planet of life.
Scientists have discovered many star systems and thousands of terrestrial planets through astronomical telescopes, but none of these planets are exactly the same as the Earth. So the Earth is still a very unique planet of life so far, and even the solar system seems extraordinary.
Why is the solar system able to give birth to a living planet like the earth? Is there anything unusual about the solar system? Through a large number of observational studies, scientists believe that life is a rare, complicated and mysterious thing in the universe, and nothing is so special as life. Since life is very special and mysterious, the planet that breeds it can’t be born casually, and many conditions need to be met.
After reaching this conclusion, scientists began to explore and study what is unusual about the solar system. Through continuous research and research, three different places have really been discovered. Scientists guess that these different places may be related to mysterious powers.
1. How does the star system form when the planets are arranged abnormally? After a large number of observations and studies, scientists believe that the star system originates from cosmic dust clusters. We all know that only after the Big Bang, time, space and matter appeared. The original matter was just a few basic elements, and these elements gathered together to form dust clusters.
The dust mass rotates rapidly under the action of gravity, and the density of the material in the center becomes larger and larger, forming an early celestial body. As matter continues to gather toward the center, when the mass and pressure reach a certain level, nuclear fusion will be ignited, and the celestial bodies will evolve into stars.
Through the formation mechanism of star systems, we should understand that the closer to the center, the greater the density of matter, and the greater the number and volume of celestial bodies that can be formed. This conjecture has been confirmed in other galaxies outside the solar system. Scientists have discovered many star systems. Observations have found that gas giant planets and other massive celestial bodies are often present in these star systems close to the main star. Many are also clustered closer to the host star.
Stars are slowly formed in the central part of the cosmic dust gathering, and although dusty matter also exists in the peripheral areas, under normal circumstances, large planets are not formed, and they are basically asteroids. The closer the planet is to the star, the bigger it should be, otherwise it will get smaller and smaller. This is a normal law of stellar system evolution.
But this kind of stellar evolution law has changed in the solar system. We all know that there are eight planets in the solar system, of which four are terrestrial planets and four are gaseous planets. Generally speaking, the mass and volume of terrestrial planets are inferior to those of gaseous planets. The same is true for the eight planets in the solar system. The mass and volume of the four gaseous planets are much larger than that of the four terrestrial planets.
According to the normal evolutionary laws of star systems, the four gaseous planets should be located close to the sun, especially Jupiter, which should have been born between the Earth and Mars in the early days. But why did it run to the outside of Mars? The other three gaseous planets also ran to the edge of the solar system, giving up the position close to the sun to the four terrestrial planets. What is the advantage of doing this?
Scientists speculate that Jupiter and Saturn were originally formed in the position of Earth and Mars, and then pushed to their current positions under the influence of external forces. So what will this external force be? Some people think it is the sun’s gravity, while others think it may be a mysterious force we don’t know.
In any case, a mysterious external force pushed Jupiter and Saturn outward, vacating a good position for Mars and Earth, and this position is very suitable for the birth and evolution of life, all this is a coincidence or a mysterious force deliberately did it of? It is still a mystery.
2. The earth has three natural “barriers”, and the earth has a suitable position in the solar system to give birth to early life. However, it takes a long process for life to evolve from the primitive stage to the intelligent life stage. It took 3.8 billion years for life on earth to give birth to human beings.
This shows that it is very difficult for life to evolve to the stage of intelligent life. Scientists, after studying Venus and Mars, speculated that they might have been planets of life billions of years ago, but they changed into the present after changes happened. The universe is not flat, especially in the solar system. The impact of asteroids can easily end the life of the earth.
Why can the earth remain safe and sound? Although in billions of years of life, the earth has also encountered five mass extinctions and countless small extinctions, but the evolution of life has been progressing. The age of life has never really restarted. The reason behind it is that the earth has three “barriers” in the solar system, and they have blocked the impact of large asteroids for the earth.
The first barrier is Jupiter. After being pushed out of its original orbit by a mysterious force, it did not randomly choose a location, but chose the front of the earth, which happened to block a large number of asteroids from the edge of the solar system for the earth.
The second barrier is the asteroid belt. The asteroid belt is located between Mars and the Earth. Its formation is still a mystery. Some scientists believe that this place may have once been a planet, but somehow it shattered into an asteroid belt.
Jupiter has blocked a large number of asteroids from outside the solar system for the earth. If there is a fish that slips through the net, the asteroid belt will play a role. There are at least 100,000 asteroids distributed here. If asteroids from outside the solar system pass through here, they can basically be blocked.
The third barrier is the Kuiper Belt. The Kuiper Belt is located on the edge of the solar system. It is a natural barrier on the periphery. There are countless various celestial bodies in suspension. To enter the solar system, celestial bodies outside the solar system have to face many challenges in the Kuiper belt.
3. The moon, the protector of the earth, is the only natural satellite of the earth. It is not strange that the planet itself has satellites. A normal-sized satellite has a very small protective effect on planets, but the mass and volume of the moon are not ordinary. It is not the largest planet in the solar system, but it is too big when placed with the earth, so big that scientists can feel it. Incredible.
In the universe, the volume of general planets and satellites will be less than 1:1000, but the volume ratio of the earth and the moon is 1:49. Looking at the universe, we have not found a second satellite system like this. The mass and volume of the moon are so large relative to that of the earth, and the impact on the earth will naturally be great.
The earth can have the current ecosystem and be able to give birth to life, thanks to the moon to a large extent. And another important role of the moon is to protect the earth from the impact of huge asteroids. The dense craters on the surface of the moon can tell how many asteroid impacts it has blocked for the earth.
The earth became the planet of life under heavy protection. After 3.8 billion years of life evolution, mankind was finally born. Today these guardians are still protecting the earth and the rapid growth of mankind. Only when mankind becomes an interstellar civilization can we truly get rid of this protected fate.
So are these unusual places naturally formed or are there some mysterious forces behind them? In this regard, scientists can’t give an accurate answer. Humans are still too weak. Perhaps only when we become an interstellar civilization and step out of the solar system can we hope to find the answer.
