I believe many friends still remember that there were nine planets in the solar system in the past, but later scientists thought Pluto was too small, just a dwarf planet, so they kicked Pluto out of the list of nine planets. From then on, there were only eight planets in the solar system.
Although there are only eight planets left in the solar system, many people still doubt the days of the past nine planets, because the number nine is of great significance to human beings. Many people expected the solar system to return to the nine planets again, and this dream was later turned around by a major discovery of scientists.
In 2014, two astronomers reported the discovery of a KBO named 2012 vp113. Its long and narrow orbit is no less than 80 astronomical units with the sun. (Pluto is 48 astronomical units away from the sun.) Vp113 joined the dwarf planet Sedna because of its distance. In this paper, Chadwick Trujillo of the Gemini Observatory in Hawaii and Scott Sheppard of the Carnegie Institute of Science in Washington, D.C., said that the orbits of these objects indicate that there is another planet much larger than Earth, which may exist in 250 astronomical units.
Orbital calculations show that if the “ninth planet” really exists, it will move in an elliptical orbit around the sun every 10000 to 20000 years. The planet will never be less than 200 solar terrestrial distances, or 200 astronomical units. This distance makes it far beyond Pluto and into the cold sphere known as the Kuiper belt.
Later, more and more scientists supported the possibility of the existence of the ninth largest planet through exploration and research. The reason why more and more scientists supported the existence of the ninth largest planet is that scientists discovered orbital anomalies when observing and studying the celestial bodies at the edge of the solar system. For example, when scientists observe some objects in the Kuiper belt, their orbits are very strange, completely different from the orbit data of normal objects.
By calculating the orbit data, scientists find that other celestial bodies in the solar system are normal. Why are only some celestial bodies on the edge of the solar system abnormal? This kind of abnormal orbit can not be caused by the gravity of the sun. The biggest possibility is that there is a planet whose mass is larger than the earth far away from the edge of the solar system. The gravitational field of this planet affects the orbit of the celestial bodies on the edge of the solar system.
Previous studies have shown that the “ninth planet” is five to 15 times the mass of the earth and is about 45 to 150 billion kilometers away from the sun. At such a distance, a celestial body receives very little light from the sun, making it difficult to be observed with a telescope. Now some scientists have begun to use telescopes to search for the ninth planet, but there is little hope.
It is possible that there is a huge gravitational source in the remote space at the edge of the solar system, which will affect the operation of many celestial bodies at the edge of the solar system. Is such a gravitational source really a huge planet? Could it be any other kind of celestial body? Recently, two physicists put forward an interesting idea, they speculated that this huge gravitational source might be a planetary black hole.
If so, it may provide a new way to find the celestial body. Whether it’s a planet or a black hole, if you want to detect an object with such mass, astronomers can look for strange clusters of light that “bend” around the gravitational field of the object as it passes through the galaxy. When a celestial body moves in front of a distant star and continues to move in its orbit, these anomalies will appear again and again.
Physicists point out that if the ninth line of the conjecture is a black hole with planetary mass, it is likely to be surrounded by a halo of dark matter, each side of which can extend to a billion kilometers away. In that halo, interactions between dark matter particles – especially collisions between dark matter and dark antimatter – may emit a beam of gamma rays, exposing the presence of celestial bodies.
Physicists will soon start combing the public data provided by the Fermi gamma ray space telescope in earth orbit to find clues, hoping to find sporadic gamma ray beams. If there is any discovery, the possibility that the ninth planet is a black hole will be very high, which will be very exciting and exciting news for scientists.
You know, black holes can be said to be the most mysterious and powerful celestial body in the universe. Although scientists have released the first picture of human black holes, and can also observe the accretion disk formed by supermassive black holes in the depths of the universe, our understanding of black holes is still only superficial, maybe not even superficial. In addition to knowing that black holes are real, we know little about other knowledge of black holes.
The only way to really solve the mystery of the universe is close observation. However, due to the super gravity and phagocytic characteristics of black holes, light cannot be reflected outward, and black holes below the planetary level are difficult to be observed through optical telescopes. Only supermassive black holes can be observed because of the existence of obvious accretion disks. However, the nearest supermassive black hole to the earth is 25000 light-years away, which is the center of the galaxy.
Such a long distance is impossible for human civilization which has just stepped out of the earth. Even if there is a black hole near the solar system, we can not go out of the solar system to observe. But if the ninth planet in the conjecture is a black hole, then human beings have the hope to go to close observation, so that they can get more information about the characteristics and data of black holes, and really uncover the mystery of black holes.
If the black hole is really a wormhole as some scientists guess, the planetary black hole that may exist at the edge of the solar system may become an important channel for human beings to connect with the outside world. We can also leave the solar system and explore other galaxies through this wormhole without realizing the speed of interstellar navigation.
Of course, if 250 astronomical units away from the earth is really a black hole rather than a planet, then it will be more difficult for scientists to observe and find it. If it is a planet, even if it is farther away from the sun, how much light will be reflected. As long as the telescope goes further, it may be able to find it. Even sent a probe to the edge of the solar system, maybe just in the same range as the orbit of the planet, it can be very intuitive to find its existence.
But if it’s a row star black hole, the situation is totally different. If it doesn’t devour celestial matter and there is an obvious accretion disk, even if the detector goes near, it may not find it, and it may accidentally enter its horizon. At this time, the detector can’t emit any signals and photons. The only thing we know is that The detector lost contact for some reason.
Of course, if scientists in the future really send a probe to the Kuiper belt to look for this object that I don’t know whether it is a planet or a black hole, once it’s in a certain position, it’s good news. It’s possible to find the location of the black hole by this. As long as the location is determined, scientists will naturally have a way to make detailed observation and analysis.
Of course, at present, scientists are still in the stage of guessing whether the ninth planet on the edge of the solar system exists, whether it is a planet or a black hole. Only by finding enough evidence can we make the conjecture come true. We can only hope that scientists can find it in the future, and we also hope that it is a reality. If it is a planet, then the solar system will return to nine planets again. If it is a black hole, it will be more significant to human beings. I hope it will not be an empty joy.
