There is a very obvious fact in front of Alex and all human beings on the earth, and that is the most basic law of conservation of mass and energy. This law shows that energy cannot disappear for no reason, so if there is some kind of blocking material in the solar photosphere, then... where does the blocked energy go?
Maybe that kind of blocking material forms an endothermic layer, but the radiation power of the entire sun is very terrifying. What kind of heat absorption layer can withstand such a huge energy shock?
A word appeared in Alex's mind, Dyson sphere.
Dyson sphere is a kind of virtual sphere that fully utilizes the energy of the sun in the speculation of human civilization. This virtual sphere can consist of many mirrors that completely envelop the entire star, absorbing all the energy it radiates.
The Kardashev index divides the possible civilizations in the universe into three levels, namely K1, K2, and K3. A K1-level civilization can utilize the energy of an entire planet, a K2-level civilization can utilize the energy of an entire star, and a K3-level civilization can utilize the energy of an entire river system. According to the Kardashev index, the Dyson sphere is the most iconic product of the K2-level civilization. Obviously, by creating a Dyson sphere, the energy of an entire star can be harnessed. And if the speculated heat sink really exists in the photosphere of the sun, is it a type of Dyson sphere?
One thing that needs to be pointed out is that according to the grading standard of the Kardashev Index, the human civilization on earth at this moment is only a K0.7 civilization, and there is still a lot of distance from the Dyson sphere. And if a certain civilization really came to the sun and created a Dyson sphere around the sun to try to absorb all the energy of the sun... Then, with the strength of human civilization K0.7, it is impossible to fight against a K2 level anyway. Civilized.
If this is really the case, then this is undoubtedly the end of human civilization.
"Fortunately, this is only a preliminary inference, it is unlikely to be true." Alex thought, "The physical world has some commonalities, even if it is a K2-level civilization that is much more advanced than us, it is unlikely to go It violates some basic laws of physics. Just like the law of gravity is still in use today when the theory of relativity has made great progress. If it is really a Dyson sphere, then it must have follow-up energy harvesting devices, and we have not observed it at this moment. to the presence of energy harvesting devices."
"The Thunderstorm Mercury probe has changed its trajectory and is rushing to the other side of the sun at full speed. We will get accurate information from the back of the sun in about five days... Everything, let's wait until then." Alex sighed He took a breath and put down the information in his hand.
Alex stood up and walked to the window.
A bright red sun hung under the western sky, and it was already evening. The air conditioner in the room was not turned on, so Alex, who had recovered from the document, immediately felt a chill. Pedestrians on the street are all in a hurry, and even the constantly flashing neon lights seem to have a depressing meaning for some unknown reason.
Virat was still missing, and he didn't know where he was hiding. Alex didn't care about him, he just took a piece of bread and swallowed it, and then sat down in front of the computer again.
This time, Alex didn't go to check some information or the like, but came to several well-known forums.
After casually flipping through some posts complaining about the recent abnormal weather, Alex refreshed the page, and a title jumped into Alex's eyes.
"The recent abnormal decrease in temperature is not due to the climate! It is the decrease in the level of solar radiation!"
Alex frowned and clicked on the post.
There is no specific observational data in the post. The poster claimed that he was an astronomy enthusiast who happened to have a set of solar observation equipment in his hand. At some point, he aimed the observation instrument at the sun, and after detailed observation and calculation came to this conclusion. At the end of the post, the poster also wrote in a very scary tone: "The government must have known about these things, but the government has concealed it, and we have reason to suspect that the government is doing something secretly. As for these actions Whether it is to build an underground shelter or a population screening program is unknown. In short, the government is unreliable now, and all we can do is save ourselves! From now on, store as much food, water and fuel as possible, earth the end is coming!
