Black holes as sources of energy for advanced civilization? Theoretical mega-infrastructures Dyson spheres can capture energy from up to 100 million suns


A new study recently proposed that advanced alien civilizations could build energy harvesting mega-infrastructures surrounding black holes to meet their enormous energy needs.

According to a Mail Online report, while black holes are “known” for their strong gravitational pull that even light cannot escape them, they also generate energy, in several different ways.

Researchers at Taiwan-based National Tsing Hua University investigated whether any of these energy sources could be hypothetically harnessed to power a civilization.

Three provide adequate radiation to be achievable. These include the surrounding gas clouds, discs of material that spiral into the hole, and powerful jets spouting along the axis of rotation.

Power generation from black holes

Such energy could be captured using the so-called “Dyson spheres”, originally considered as a theoretical approach to better capture the energy of a star like the Earth’s sun.

Nonetheless, according to the research team, black holes could provide as much energy as the total harvest of 100,000 to 100,000,000 suns, albeit from a single cosmic body.

With the existence of Dyson’s spheres, they would produce a characteristic signal that could be detected. This is due to the waste heat produced, as they convert energy into a usable form.

In fact, Dyson’s usual spheres, those surrounding suns, have long been targets in the quest for alien life. At present, however, none of these spheres have been found.

The “Dyson spheres”

In a similar report, the Today UK News described the Dyson spheres as “theoretical megastructures” which, as previously mentioned, as they were originally envisioned, could be built around stars to better exploit their energy.

Despite their name, it would be impossible for a rigid sphere to build around a star or a black hole, due to the forces of pressure and gravity.

They are generally viewed instead as being made up of an array of satellites encircling their host in a spring, swarm, or ring arrangement.

As specified in this report, humans do not currently have the ability to build a Dyson sphere, although they may someday.

Black Hole, a promising source of energy

The study, A Dyson sphere around a black hole, published in the journal Monthly Notices of the Royal Astronomical Society, was conducted by astronomer Tiger Hsiao of National Tsing Hua University and his colleagues.

Explaining their article, the researchers said that a black hole may be a promising energy source. It is also more efficient than harvesting from a “main sequence star”.

They added that “great luminosity can be obtained from an accretion disk” which reaches 100,000 times that of the Sun, which is enough to maintain what they call a “type II civilization“.

This type of civilization, explained the authors of the study, is one whose energy needs correspond to the total production of a star system.

In addition, the team added that if a civilization could build a Dyson sphere, a “supermassive” Milky Way-like black hole weighing about four million times the mass of the sun, the energy supply could be even greater. important.
