One possible solution would be Disney’s sphere – a whole star (or, in this case, a Black hole) In an artificial cover that holds all the energy of the object in the center. But even though the black hole can hold all the energy it produces, Lulu itself still suffers from heat loss. And this heat loss is visible to us, according to a new study by an international team led by researchers at Ting Hua University in Taiwan.
Clearly, no such structure has ever been found. Still, the spherical surface and the black hole rain show more light than light sources, and the paper confirms that this can be done even if there is no visible light. To understand how we can identify such a system, we first need to understand what that system is.
The authors study six different sources of energy that could be gathered around the black hole. They are the ubiquitous cosmic microwave backlight (which washes the ball wherever it is placed), the black hole hawking beam, the addition disc, the bondi addition, the corona and the related planes.
Some of these sources of energy are more powerful than others, and the power from the black hole joint disc is moving in terms of the total capacity. Other types of energy require a wide variety of engineering tests to capture the kinetic energy of the corresponding jets emanating from the black hole poles. Size plays a big role in how much energy these black holes emit. The authors’ main focus is on the star-studded black holes, which, like other good sources of energy, are good points. At that rate, the addition disk alone provides hundreds of times the power output of the main series.
It is impossible to build a Dyson sphere around anything that is comparable to modern materials. But the kind of civilization that is interested in taking on such an engineering test may be a much stronger material than we have today. Alternatively, they can be made of known materials to create a Dyson Swar or Dyson foam, which does not require much material strength but lacks a certain amount of energy and adds a number of complex layers when coordinating orbits. And other reasons. To take full advantage of the power of a black hole, any such structure must be outside the storage disc.
Even a single sphere around a star-shaped black hole would suffice for any civilization that has created an unimaginable level of energy output with the help of modern technology. But even such a powerful civilization cannot break the laws of physics. Regardless of the level of energy, some will be lost in the heat.
For astronomers, heat is simply another kind of light – infrared, precisely. And according to the researchers, the temperature emitted by the Dyson sphere around the black hole should be determined by current telescopes, such as the wide field infrared sensor and the Sloan digital Sky sensor, at least 10 kW. . That’s about 1/3 of the total distance Milky Way. No matter how close they are, they do not look like traditional stars, but they can often be identified by the radial velocity method they use to find foreign planes.
While this is an important theoretical work, there is still no evidence of such a structure – the formal paradox still exists. But with all the information we are collecting from these telescopes, it may be interesting to look at them once and for all. It will be worth the time to explore what such a fundamental discovery could be.
