From the perspective of biological evolution, not only human beings are breeding civilization, but there are many social animals in the region, but the social form of human beings is the most complete and complex relying on super-high intelligence. From the perspective of human beings, other The social situation of organisms is very simple, such as “ants”, “wolves”, and “lions”. These animals all have family-based social forms, and they have social relationships and different social status.
So, if there are other advanced civilizations in the universe, in their eyes, is the human civilization and social form full of loopholes? The emergence of civilization is accidental, and perhaps it is also inevitable in the process of biological evolution. Then the universe is so big, is there a “super civilization” with very advanced technology in the universe? In fact, scientists have discovered some suspicious phenomena in the universe.
Stars – an inexhaustible source of energy
In 1960, Freeman Dyson put forward the famous “Dyson Sphere Theory”. He pointed out that the energy on a planet like the earth combined is not enough for the infinite development of human civilization. At present, human beings are only developing at a high speed. For hundreds of years, the earth’s environment has been overwhelmed, and various energy sources have begun to run out.
In the universe, basically all planets revolve around stars. For civilizations on planets, the energy of stars is almost endless. The nuclear fusion reaction inside stars makes these hot stars release energy all the time. As far as human civilization is concerned, solar energy can provide human beings with a large amount of clean energy, but most of the energy radiated by the sun cannot be rationalized by human beings. Therefore, he judged that with the development of human technology, we may be able to build a spherical structure to put The entire star is wrapped up, making full use of the energy radiated by the star.
At present, most of the energy on the earth can be regarded as an alternative solar energy. Therefore, in the future, if human beings can really build a “Dyson sphere”, then the price of energy will continue to decrease, prompting the rapid development of human civilization.
Since humans can conceive of artificial celestial bodies such as “Dyson spheres”, in the universe, if there are other civilizations, is it possible that a civilization has built a “Dyson sphere” and captured a star to obtain a large amount of energy?
First of all, Dyson spheres are not necessarily spherical. They have a variety of shapes. They can be in the state of “clouds” that pervade galaxies, or they can be a bubble-like shape that wraps stars, perhaps in countless small structures. In all “Dyson networks”, as long as the energy emitted by the stars is collected around the stars, they can be called “Dyson spheres”.
NASA’s Kepler mission, which has observed hundreds of thousands of stars in the universe, discovered such a strange star KIC 8462852, also known as Tabby’s star or Boyajian’s star. Boyajian’s star, located 1,480 light-years away from Earth, many believe that this star may have been captured by other civilizations using Dyson sphere-like equipment.
Around this star, there are no planets, only some irregular-shaped creations are blocking the light of this star, and the overall brightness of this star has multiple dips in different periods, you know, such as Jupiter, huge The star of Tabby’s two brightness dips caused a decrease in brightness of 15% and 22%, respectively.
Some astronomers speculate that the reason for this phenomenon is that an alien civilization is building a “Dyson sphere” around this star. After all, Rome was not built in a day, and a huge artificial celestial body around a star is naturally impossible to form at one time. May 19 Japanese scientists found that KIC 8462852’s brightness began to change again, with the star dimming by 3 percent in just a few days.
If in the future, humans can also build Dyson spheres, it can also bring another benefit – cooling Venus, and at the same time transforming Venus into a habitable planet with the help of the huge energy of Dyson spheres, but we also need to consider changes in the brightness of the sun impact on the global environment.
Of course, the brightness change of Tabby’s Star can’t be 100% sure that aliens are building Dyson spheres, just because the performance of this star is surprising, and at the same time, there is no planet around this star. , Scientists believe that if a civilization can build a Dyson sphere, there is a high probability that it will not choose the star in the galaxy where its parent star is located. After all, the brightness and radiated energy of stars have a great impact on the ecosystem on the planet. If Tabby’s Star is really reduced in brightness by the influence of the Dyson sphere built by an alien civilization, then this civilization will be far more developed than human imagination.
Therefore, the alien civilization that transformed Tabby’s star may come from other distant galaxies. Can human beings also capture stars and obtain a large amount of energy in the distant future? This is still an unknown. After all, the Dyson sphere is just an imaginary that stays in the theoretical stage. To truly realize such a huge artificial star, it needs to consume unimaginable materials, and it also needs corresponding technology to make reasonable use of the stars brought by the stars. huge energy.
