There is a star suspected that there is Dyson ball. What can it mean?Not necessarily a good thing

There is a star except for the 1480 light years away from Earth. Its number is KIC 8462852. It was discovered that in 2009, once this star was discovered, it aroused the interest of astronomers around the world.

KIC 8462852 is a slightly larger star than the sun. The quality is about 1.43 times the quality of the sun, and the diameter is about 3.16 times that of the sun. This kind of star cannot be seen directly with the naked eye at the distance of 1480 light years. Why does such a stars that look flat make astronomers so fascinated? Because this star has changes in brightness, and the change of this brightness has two forms of periodic and non -periodic, which will occur once every 750 days. This is a phenomenon that does not conform to common sense, because even if it is an unstable ultra -quality star, its brightness will not occur such obvious periodic changes.

There is only one reason that a star appears such a significant brightness change, that is, what is blocked by something.

What is it? Astronomers immediately thought of Dyson. Dyson's ball is an idea proposed by American physicist Dyson. The degree of development of a civilization is inseparable from the energy sources that this civilization can obtain and use. The higher the level of civilization, the more energy that can be obtained and used. For example Cosmic civilization is to be able to use all the energy sources of the galaxy system. Taking the earth as an example, if the entire energy generated by the sun can be obtained and used by the sun, it can reach the second -level cosmic civilization.

Based on the current energy consumption of human beings, the energy generated by the sun can be used for millions of years per second, and the solar energy we can receive on the earth's surface is actually minimal.

So how can we get all the energy generated by the sun? That is to build the Dyson ball. The so -called Dyson ball is simply a device that can wrap the sun and collect solar energy. It can be a hollow sphere or a ring. If it is a ring, it is called the Dyson ring. Essence Of course, this device is just out of the imagination of Friman Dyson, and it does not realize it, but this imagination has been widely recognized by the scientific community. However, after all, it is a false imagination. Humans have not really discovered the Dyson ball in the universe, and the appearance of KIC 8462852 seems to make everyone see hope.

However, after many years of observation research, scientists have obtained some evidence that these evidence shows that the brightness changes of KIC 8462852 are not formed by the cover of Dyson. This periodic shading phenomenon should be derived from the interstellar dust around the star.

This conclusion makes many people feel disappointed and can witness the existence of alien civilization in my lifetime. I don't know how many people's dreams. But then again, if the KIC 8462852 has Dyson, what does this mean? If KIC 8462852 really exists Dyson, it may not be a good thing for humans. Civilization that can have Dyson ball is a very high degree of civilization, and the earth civilization has not even reached the first level of civilization, so it is almost impossible to achieve communication. Mechanics, the picture must be full of absurdism.

In fact, the gap between the earth's civilization and the second -level cosmic civilization is larger than the gap between Planck and the two -year -old children. In front of the second -level civilization, we can only be regarded as "bugs".

If we can find them, it means that they have already discovered us. I don't know when they may appear in front of us. What will happen at that time, no one can predict, but it will not be like science fiction works. As described, they come to grab the resources of the earth, but they can collect the energy of the stars, and the resources on a planet are not worth mentioning at all. It is a terrible thing to come to us in front of us, but if they are not here, it is also a terrible thing.

If KIC 8462852 really exists in Dyson, and this advanced civilization has not visited the earth, this shows that even if it reaches the height of the second -level cosmic civilization, the distance that wants to cross 1480 light years is still unwilling.

That is to say, no matter how a civilization develops, it cannot break the constraints of the speed. What is one -half of the speed and one -third of the speed of light is difficult to achieve. It takes 1,4800 years, which is too long. In other words, all civilizations will be bound to a certain area of ​​activity. We can never jump out of the shackles created by the universe for us. Desperate things, this feeling is as helpless as "no matter how hard we work hard, it will eventually turn into a ray of green smoke."
