There are two kinds of magical things in the vast universe, each of which may break human cognition

13.8 billion years ago, a mysterious singularity exploded, and the universe was born. After the birth of the universe to exceed the speed of light in the rapid expansion, but also continue to form a variety of materials in the universe, celestial bodies and some of the rules of the universe. After 13.8 billion years of evolution, we have finally formed the vast, complex and mysterious universe we see now.

With the help of science and technology, mankind finally walked out of the earth half a century ago and saw the vast universe. At that time, we also had a preliminary understanding of the universe, and with the rapid development of human science and technology, our understanding of the universe is also constantly improving. Now, the exploration and research of the universe is mainly through astronomical telescopes. Through a lot of observation and research, scientists not only found some common phenomena in the universe, but also found two magical things, each of which may break human cognition.

The first wonder: there may be at least 100 billion wandering planets in the Milky way. For the cognition of wandering planet, many friends understand it after watching wandering earth. In this film, because the sun is about to flash helium, scientists for the future of mankind, so the earth has been transformed, to install tens of thousands of planetary engines, and then the earth into a wandering planet, toward the distant galaxy of beling.

Through the film, many friends know for the first time that there are wandering planets in the universe. In fact, wandering planets are not uncommon in the eyes of scientists, because through a large number of observations, scientists have found many wandering objects, including not only wandering planets, but also wandering stars, and even wandering neutron stars.

Although many people know that there are stray planets in the universe, few people know how many stray planets there are in the galaxy. If someone asks you this question, you may say that wandering planets should be a rare kind of celestial bodies in the universe, and the number should not be too many. But this is not the case.

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%.

According to this ratio, there will be at least 100 billion wandering planets in the galaxy with a diameter of 100000 light-years. This is a huge number. If there are 100 billion stars in the galaxy and each star has an average of eight planets, then the number of planets in the galaxy will reach more than 800 billion. The number of stray planets is one eighth of that.

So how did wandering planets form? We should know that the largest star is the star in the center, and its mass generally accounts for more than 90% of the mass of the whole stellar system. The absolute mass advantage makes the star’s gravity very strong. Under normal circumstances, the planets in the galaxy can’t leave the star’s gravity range. Some people think that the collision force of planets can make the planets free from the bondage of stars.

But in fact, the collision force in the galaxy is very weak compared with the gravity of the star, which is unlikely to make the planet escape. In the early days of the solar system, the earth may have suffered a planetary side impact, and the debris from this impact eventually formed the moon. But this kind of impact didn’t make the earth a wandering planet.

It is inevitable that a large-scale catastrophic event can break away from the gravitational bondage of a star, and this event may be a supernova explosion. As we all know, the star system in the universe is not only a single star system like the solar system, but also a double star system and a three-star system. In other words, there are two or three stars in the galaxy, and the neighbor billing galaxy of the solar system is a three-star system.

There are many stars in a galaxy, and the masses of these stars will vary greatly. Some stars may be similar to the sun, while some stars may have very large masses. The lifetime of a star is inversely proportional to its mass. The larger the mass, the shorter the lifetime of the star. Some massive stars have a lifetime of only a few hundred million years or tens of millions of years.

When the life of a massive star comes to an end, supernovae often explode, which is the most powerful explosive force in the universe. The thrust generated by supernovae is enough to throw out some nearby planets and become wandering planets. Of course, there is another way to become a wandering planet, that is, intelligent civilization transforms the planet through the power of science and technology to make it a wandering planet.

Therefore, the wandering planets in the universe may not be all formed naturally, some of which may be the survival planets of advanced civilization. The purpose of advanced civilization may be to better explore the future. We should know that it is inevitable for a civilization to go out of the galaxy and explore the universe after it has developed into a higher civilization. At this time, they want to keep the parent star at their side all the time, so they have to transform it into a planetary spaceship.

The second magic thing: the light of stars suddenly darkens by 80%. Scientists observe and search for planets outside the solar system, mainly by transit method. That is, the change of light and dark when the planet passes through the main star. If there are planets around the star, the main star it revolves around will have periodic light and dark changes.

When we find that a star has periodic light and dark changes, we can be sure that there may be planets around it. But the magnitude of the light and dark changes caused by this kind of planet will be very small, but if scientists find that the light of a star suddenly darkens by 80%, what would you think? Many people may think that there will be a civilization creation Dyson sphere around this star?

Scientists have been 440 light-years away from the earth, the observation found a star, the star suddenly darkened by 80%. Such a thing is absolutely abnormal, which means that there is a huge object around the star. What will this object be? Some people say it could be a celestial body? Scientists quickly denied that it was such a huge object to be able to block 80% of the light of a star.

If there is such a natural celestial body around the sun, it will not be a planet, because the planet can not grow to such a huge extent. It is no longer likely to be a Dyson sphere, because the magnitude of the dimming caused by the Dyson sphere is about 22%. So what would it be? Some people have come up with the possibility that a super spaceship can match a star.

Maybe someone will say, can a spaceship build such a big one? In fact, the power of science and technology is infinite. When science and technology reaches the end, it is possible to create galaxies and universes, let alone a spacecraft as big as a star. When a civilization reaches an advanced stage, it may be able to build such a huge spaceship. You know, for a high-level civilization, the materials for making spaceships are not a problem at all. The materials for the universe are endless.

Of course, it’s just people’s conjecture that what is the object that causes 80% of the star’s light to darken? It also needs the continuous observation and research of scientists. If the change of light and dark is not periodic, it just happened once, and it will not be observed in the future. So it’s very likely that a huge spacecraft will block the light from the star. It’s possible that the super spaceship of advanced civilization was sailing through the star, which inadvertently blocked the light and was observed by us.

There are many magical things in the universe. The above two are just the tip of the iceberg. With the continuous progress of human science and technology, the future observation technology will continue to be powerful. At that time, we will find more things beyond our cognition. Of course, to solve the mysteries behind these things, we still need the continuous progress of science and technology to become an interstellar civilization as soon as possible. At that time, we will have to explore more mysteries in the universe.

Guys, what do you think of this? Welcome to leave a message below to discuss and express your opinions.
