There are three strange and mysterious things in the universe, each of which may break human cognition

Since the big bang 13.8 billion years ago, no one knows how big the universe is now. While the universe is expanding, it has also formed various celestial bodies and cosmic rules. Under the influence of these rules, the universe has also formed various strange and mysterious things that subvert people’s cognition. Through the observation and research of the universe, scientists have found four strange things in the universe, each of which may break the human cognition of the universe.

1、 There may be 100 billion wandering planets in the galaxy with a diameter of 100000 light-years. I believe many friends have seen this year’s very popular science fiction film wandering earth, in which the sun is about to flash helium, threatening the earth and human beings. In order to get rid of the disaster, scientists have installed tens of thousands of planetary engines to push the earth to leave the solar system and become a wandering planet.

After watching this film, many people know the concept of wandering planets, but many people think that the number of wandering planets in the universe should be very small, but is it really so? A new study from Leiden University in the Netherlands has found that many star systems in the Milky way have planetary derailment. After studying a number of stellar systems in the Orion Nebula, scientists have determined that the rate of planetary derailment in the stellar system is about 16.5%.

If calculated according to this data, there will be at least 100 billion wandering planets in the galaxy with a diameter of 100000 light-years. Although this number is not much compared with the planets in the whole galaxy, it is also a very terrible number. If there are 100 billion stars in the Milky way, and each star system has an average of eight planets, then the number of planets in the Milky way is more than 800 billion, and 100 billion is already one eighth of it.

Some scientists believe that in the early days of the solar system, there was a wandering star, and now we see Uranus’s oblique orbit may be caused by the passing of wandering planets. So what are wandering planets? Why do some planets leave the galaxy and become wandering planets?

Wandering planets are also called interstellar stars, aka orphan planets. Roughly speaking, they are planets that do not revolve around any stars. They originally revolve around their own stars and are thrown out of the planetary system after being influenced by the gravity of other planets and other celestial bodies, wandering in the galaxy or universe. Under normal circumstances, planets will move around a star, with their own stable orbit, such as the eight planets in the solar system.

However, at special times, some planets may be thrown out of the galaxy and become wandering planets. What kind of circumstances can throw planets out of the stellar system? If it is the collision of celestial bodies in the galaxy, the planets will not be separated from the stellar system. Even if two massive planets collide with each other, it is difficult to get rid of the star’s gravity. When the earth was formed in the early days, it was also hit by a planet the size of Mars, but it didn’t throw the earth out. Thus, it can be seen that a stronger force is needed to throw planets out of the solar system, and the collision force between celestial bodies is far from enough. So what kind of force can be achieved?

The only thing a galaxy can have so much power is stars. I believe many friends know that there are not only single star systems like the solar system in the universe. Many galaxies have at least two stars, which we call binary star systems. If there are binary star systems, there will naturally be three-star systems. For example, the leading Bilin Galaxy in the solar system is a three-star system. Many science fiction works assume that the alien civilization is located in the galaxy.

There will be at least two stars in a multi star system. These stars have different masses. One of them may be a red dwarf with the same mass as the sun, and the other may be a massive star. As we all know, the lifetime of a star is closely related to its mass. The greater the mass, the shorter the lifetime. For a star like the sun, its lifetime is about 10 billion years, while for a star with large mass, its lifetime may be only a few hundred million years or tens of millions of years.

When a star reaches the end of its life, it expands to become a red supergiant and then collapses inward. In this process, a supernova explosion occurs, which is the most powerful explosion in the universe and can destroy a galaxy. When a star supernova explodes, its super strong energy can easily throw out the planets in the galaxy, and sometimes even another star will be thrown out to become a stray star. This is where the wandering planets come from.

2、 440 light-years away from the solar system, a star suddenly darkens by 80%. In the universe, it is normal for the light of the main star to have light and dark changes, mainly because the planet will block the light when it revolves around it. However, the light line of the main star will not darken by more than 3%. Even if there is a Dyson sphere, the Star Building of alien civilization, which scientists suspect, its light will darken by 22% %。

However, scientists found a red dwarf named epic 204376071 in a galaxy 440 light-years away from the earth. Its light suddenly darkened by 80%. What’s the situation? This is definitely not caused by the shielding of planets and other celestial bodies. You should know that it can block 80% of the star’s light. If it is a celestial body, it will be very huge. However, it is impossible for such a celestial body to appear near the star, otherwise it would have collided with the star.

Some scientists said that it is unlikely to be caused by Dyson sphere, it may be a super planet or dust cloud. Is that true? We must first rule out the possibility of a super planet, because under normal circumstances, there can be no planets as big as stars. If there is such a huge planet, it is no longer a planet, but has already become a star. So could it be a dust cloud? This seems unlikely. The formation and shielding of dust clouds can not be achieved in a short period of time. Scientists observed that the star broke through and darkened by 80%, which indicates that something suddenly blocked in front of the star. So what will this thing be?

Xiaobian thought of a possibility, that is, a huge alien spaceship. It is impossible for a planet as big as a star to exist or break through in front of the star, but alien spaceships are different. We should know that the power of science and technology is endless. If a civilized science and technology has developed to the era of interstellar navigation, it is not impossible to create a spaceship as big as a planet or even as big as a star.

It is possible that the alien civilization spaceship just passed by the star during the interstellar journey, and the huge spaceship blocked the star, and the light suddenly darkened by 80% is normal. After the spaceship left, the light of the star returned to normal again. Therefore, about this star light suddenly darkens 80%, mainly depends on whether the same situation will appear later.

If it doesn’t appear again, it means that there was a huge foreign object suddenly blocking in front, and the most likely one was the spaceship. If it is a celestial body, it may have a fierce collision with the star early, and it will show stronger energy light. However, what we have observed is that the light suddenly darkens by 80%, and we have not found any huge energy change of other stars.

3、 There is a large amount of toxic grease floating in the space. I believe we are not unfamiliar with it. It is found in our daily life and in all walks of life of human civilization. But many people don’t know that our universe is also full of grease, which is also a kind of poisonous grease.

A study from the University of New South Wales in Australia found that there are a lot of oil atoms in the dust that widely exists in interstellar space. The data show that there are 100 oil carbon atoms in 1 million hydrogen atoms, which account for 1 / 4 of the total carbon in the universe. If calculated by this ratio, there are 4 trillion barrels of oil in the Milky Way alone. We know that oil has a strong viscosity, so the future of human spaceship may be equipped with “oil brush”.

The existence of a large amount of grease in space is very disadvantageous to the navigation of spaceship. It is easy to form a grease layer on the outer layer of spaceship. At the same time, the grease will also plug some important positions such as the engine. If it is not cleaned up in time, it may bring damage to the spaceship. Therefore, in the future of human interstellar navigation, cleaning grease will be an essential daily work.

The above three are just the tip of the iceberg of many strange and mysterious things in the universe. There are many magical things in the universe, and there are many mysteries waiting for human to explore and solve. And human civilization is advancing step by step in the constant exploration and disclosure, and finally becomes the most powerful civilization in the universe.
