What is the dyson sphere?
dyson sphere is a hypothetical structure of huge size. It is a ball that completely (or almost completely) closes the star and uses all the energy emitted by fusion reactions that take place in its core. The idea of Dyson's sphere was firstized and popularized for the first time by renowned physicist Freeman Dyson in the 1959 article in science The title "Search for artificial star sources of infrared radiation". Around 4 x 10^26 watts, or approximately 100 million times the total energy consumption of humanity during the last century every second. If this energy could be used through the Dyson sphere, we would have enough energy to keep the population trillion, when our current population for many sciences.
The original design on the Dyson sphere was not for a fixed ball, but for the collection of objects ~ 10^5, which collectively absorb most of the sun's energy. OneY is called "Dyson Swarm", which would allow the system's incremental design, with sub -components orbiting the star separately. From the outside, such a swarm would seem black and only infrared radiation. Some of our orbital infrared telescopes have been looking for bodies such as Dyson balls or swarms for decades, without happiness. If reflectors were used on the interior of objects, radiant energy could only be focused on one way, making it difficult to detect from a distance.
Thepreliminary calculations have shown that our solar system contains plenty of stiff matter to create a dyson swarm, but probably not a rigid Dyson ball that would have to be a thick of about a million km (600,000 miles) to be stable. Buckminsterfullerene, allotrope carbon with great force.
Dyson's sphere is often mentioned in conjunction with the classification scheme of Kardashev, a method used to classify hypothetical civilizationsYour energy sources. According to this classification scheme, type I civilization would be one that uses the energy sources of the whole planet, type II civilization would be one that uses the performance of the whole star, and type III civilization would be one that uses the whole galaxy for power. The more specilic civilization of type IV would be one that uses the power of the entire universe. The design of the Dyson sphere would place civilization directly into the type II category.
