These predictions were later proved to be false by scientists, and there is no evidence that these predictions came from the mouth of the Mayans.
Now it is said that the ninth planet is related to the Mayan prophecy, but the Mayan prophecy did not mention the ninth planet. The solar system will undergo "great changes" and the ninth planet will come out soon. These are similar rumors, but they may come from some scientific discoveries. Let's take a closer look.
4.6 billion years ago, the solar system was only located in some interstellar matter, mainly gas composed of helium and hydrogen and some interstellar dust. Under the gravity of the other side, these substances begin to rotate and fall to the center, where they gather into spheres, and other interstellar substances gather on the spherical equatorial plane.
With the continuous shrinkage and accumulation of materials, the density of the center is getting higher and higher, and the temperature is also rising gradually, and finally a lot of heat is released. At this time, this star is called the protostar of the sun. The matter gathered on the equatorial plane of the protostar forms a protoplanetary disk with a diameter of about 200AU( 1AU stands for the average distance of one day).
Interstellar matter is still gathering towards primitive stars. When the center temperature exceeds100000 degrees Celsius, the nuclear fusion reaction begins. When interstellar matter gathers to produce heat energy that can resist gravity, the sun is formed.
The sun occupies 99.86% of the mass of the solar system, and the nuclear fusion reaction constantly occurs inside it, producing a large number of plasma, also known as the solar wind. This makes the material around the sun blown around, and the particles such as heavy rocks can't be blown away by the solar wind, so they stay near the sun, while the light gas is blown far away.
Heavier particles eventually collide with each other under the action of gravity, and eventually form smaller asteroids. These asteroids eventually grow into rocky planets such as Mercury, Venus, Earth and Mars after repeated collisions and fusion.
On the planet with inactive surface geological movement, there are still traces left by collisions billions of years ago, such as Mercury.
Lighter gases eventually formed gas giants, such as Jupiter and Saturn. Farther away, due to the low temperature, the gas freezes, forming ice giants such as Uranus and Neptune.
Further in the solar system, there are many asteroids due to the gravity of the sun, which is called the Kuiper Belt. Further in the Kuiper Belt, scientists assume that there is a spherical nebula around the solar system, called Oort Cloud, which is also considered to be the birthplace of comets.
On August 24th, 2006, Pluto was downgraded to a dwarf planet by the International Astronomical Union (IAU). Why are you doing this?
1930, Pluto was first discovered by humans, and it was also the first celestial body located in the Kuiper Belt, about 40AU away from the Earth. Standing on it and looking at the sun, you can only see a bright star.
Pluto's surface temperature is between -235℃ and -2 10℃, and its surface is mostly an ice layer condensed by methane and nitrogen, only about 1/3 of that of the moon, but it is the largest dwarf planet in the solar system.
Pluto was "downgraded" because the International Astronomical Union's definition of the planet has changed. The new definition requires the planet to:
Pluto's first two items are satisfied, but the last one is not, because Pluto's mass only accounts for 7% of the mass of all celestial bodies in its orbit. In contrast, the mass of the earth is 6.5438+0.7 million times that of all celestial bodies in its orbit.
Only Phobos is about half the size of Pluto. Can you imagine a planet half the size of the earth called the satellite of the earth?
In addition, Pluto's orbit is also highly inclined, deviating from the ecliptic plane 17 degrees. For various reasons, Pluto is not considered a real planet.
On 2016 65438+1October 2 1, Brown, a professor of planetary astronomy at California Institute of Technology, published a paper in Astronomy magazine, saying that through mathematical modeling and computer simulation, a huge celestial body was discovered, its mass was about 10 times that of the earth, and it was particularly far from the sun.
Professor Brown believes that this may be the real ninth planet. Its gravity is quite strong, and it can clear the celestial bodies near the orbit, which definitely conforms to the definition of a planet.
But in July 2020, a paper in Physical Review Letters said: This is not the ninth planet at all, but it may be a primitive black hole, about half the size of a bowling ball.
This explanation seems to work in theory.
However, does the ninth planet really exist or a black hole? There is no direct observation data of this celestial body at present, so it is impossible to draw a conclusion. If the ninth planet really exists, it can explain the strange behavior of many celestial bodies in the Kuiper belt outside the solar system, which is also a basis for scientists to speculate on its existence. As for whether it really exists, there is no answer yet.
However, with the progress of science and technology and the deepening of research in the future, scientists will definitely have the opportunity to find out the true face of the "ninth planet"! Maybe in the future, our textbooks will be rewritten again!
