Alien 'Dyson spheres' could be harvesting the power of black holes
From Dyson's Sphere to Dyson's Hole.. Build sphere to enclose a singularity. A Dyson's Hole...
Use the singularity's gravity and centrifugal force for simulated earth like gravity while tapping the accretion disk for power and raw materials while waste materials go down "the hole.."
Possible benefits.. Decreased visibility in a universe potentiality filled with bigger badder brain sucking aliens - and a zero carbon footprint..!

In 1960, physicist Freeman Dyson put forth a paper in Science that changed the way we talked about alien civilizations.
In it, Dyson conjectured that a sufficiently advanced civilization would harness the power of its home star to generate power on a massive scale. He also proposed that nascent search for extraterrestrial intelligence (SETI) programs should “search for sources of infrared radiation” to “accompany the recently initiated search for interstellar radio communications.”
These structures became known as Dyson spheres, and a handful of programs have sought them out by looking for weird infrared signatures around neighboring stars. But what if a more advanced extraterrestrial civilization is not only building megastructures that surround stars, but turning to the infamous beasts of the cosmos for energy: black holes.
A recent paper published in Monthly Notices of the Royal Astronomical Society suggests that scientists should start to look for Dyson spheres around black holes as an indication of an alien civilization.
The concept of Dyson Spheres is extraordinary by itself, but what happens if one is created around a black hole? The first thing that comes to mind is that it would be impossible since extracting something from a black hole goes against the obvious nature of these objects. Nevertheless, this is not exactly correct. Scientists focused on stellar-mass black holes that extract energy from a normal star. In these binary systems, the material that is being pulled by the black hole forms an accretion disk of gas that revolves around the black hole before it passes through the event horizon.thousands of times the energy of a regular Dyson Sphere. And according to scientists, such an achievement will be the mark of the most advanced type of civilization – Type III. Of course, even if alien civilizations exist, no one could know if they would have the engineering capacity to create even a regular Dyson Sphere. But that does not mean that we should not consider it.

Black holes make better engines for Dyson Spheres than stars
Scientists have upped the ante on theoretical Dyson Spheres with a proposal for alien civilizations constructing the colossal megastructures around stellar mass black holes, pushing the energy harvesting power well beyond what could be possible with just a traditional Dyson Sphere.
In a new study published in the Monthly Notices of the Royal Astronomical Society, researchers from Taiwan's National Tsing Hua University (NTHU) dig into the energy output from a stellar mass black hole and found that the energy captured would be immense and would dwarf the amount of energy captured by their own sun.
"An accretion disk, a corona, and relativistic jets could be potential power stations for a Type II civilization," the researchers write. "Our results suggest that for a stellar-mass black hole, even at a low Eddington ratio, the accretion disk could provide hundreds of times more luminosity than a main sequence star."

Type III Alien Civilizations Likely Harness Energy Around Black Holes Using Massive Dyson Spheres
Vladislav Tchakarov Posted on April 15, 2022
A new paper suggests that an advanced alien civilization should be capable of extracting energy from black holes by building massive Dyson Spheres around them.
Energy as a factor in the development of civilization
Energy is a key factor determining the development of civilization. Energy is needed to produce food and clothing, build houses and cars, develop new drugs, launch rockets, and almost anything else in modern life. However, mankind uses only a small part of the theoretically available energy. Currently, most of our energy (about 67 percent) comes from burning fossil fuels—coal, oil, and gas. Suppose we imagine that people covered the entire surface of the Earth with solar panels or learned how to control thermonuclear fusion and “burn” the hydrogen contained in ocean water. In that case, energy production could be brought to a much higher level – about ten thousand terawatts. According to futurologist Michio Kaku, humanity can reach this level within the next 100-200 years.

Could we use a Dyson sphere to harvest energy around a black hole?
Advanced civilizations could build giant power generator structures around black holes and we could even detect them.

The Search for ExtraTerrestrial Intelligence (SETI) is more than just pointing our telescopes to distant stars hoping that some habitable planet is orbiting it. It also has to do with imagining all possibilities, but more importantly the plausible ones.
In a recent study, scientists analyzed the possibility of an advanced civilization harvesting energy from a black hole. The idea comes from the concept of the Dyson sphere, a hypothetical structure built around a star by an advanced civilization to collect energy remotely from it.

A Dyson Sphere Around A Black Hole
In this study, we discuss whether building a Dyson Sphere around a black hole is effective. We consider six energy sources: (i) the cosmic microwave background, (ii) the Hawking radiation, (iii) an accretion disk, (iv) Bondi accretion, (v) a corona, and (vi) relativistic jets. To develop future civilisations (for example, a Type II civilisation), 4×1026W(1L⊙) is expected to be needed. Among (iii) to (vi), the largest luminosity can be collected from an accretion disk, reaching 105L⊙, enough to maintain a Type II civilisation.

Dyson spheres – capturing energy with a mega-constellation.
One possible way to obtain energies on astronomical scales is with a Dyson sphere. This is a structure surrounding an energy source like a star or a black hole, capturing the sources’ energy. One example would be a sphere around the sun made up of solar panels, which capture all the sun’s light.

Civilizations need to harvest energy. This is not only the case for humanity but also for extraterrestrial civilizations. We do not know what kind of technology aliens use, but it must require energy. A popular way to classify alien civilizations is by their energy consumption with the Kardashev scale (explained in this bite). Type I civilizations use all the energy of their home planet. Type II civilizations use all the power of their home star, and Type III civilizations use the energy from all stars in their home galaxy. Humanity does not even classify as a Type I civilization on this scale, so we are relatively unadvanced from a cosmic perspective. But how could more advanced aliens obtain enough energy to progress beyond type II, ? Todays’ paper discusses an intriguing possibility: harvesting black holes.

Weaponizing a Dyson's Hole:

For the first time astronomers have witnessed a supermassive black hole blasting its galactic neighbor with a deadly beam of energy.
The "death star galaxy," as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in the wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos.

A powerful jet from a supermassive black hole is blasting a nearby galaxy in the system known as 3C321, according to new results from NASA. This galactic violence, never seen before, could have a profound effect on any planets in the path of the jet and trigger a burst of star formation in the wake of its destruction.

Alien 'Dyson spheres' could be harvesting the power of black holes
ET could harvest energy from a black hole.
Technologically-savvy aliens could be powering their society using a hypothetical megastructure called a Dyson sphere to harvest energy from a black hole. And the sphere might radiate in peculiar ways, allowing telescopes on Earth to discover the existence of intelligent beings elsewhere in the universe, a new study suggests.
A Dyson sphere is a speculative structure that would encircle a star with a tight formation of orbiting platforms in order to capture starlight and produce power, according to Live Science's sister site Space.com. First proposed by theoretical physicist Freeman Dyson in 1960, the idea might be realized by a spacefaring extraterrestrial species who had spread out across their star system and therefore required ever-increasing amounts of energy.

Advanced civilizations could be using Dyson spheres to collect energy from black holes. By Andy Tomaswick, Universe Today.
Black holes are more than just massive objects that swallow everything around them—they're also one of the universe's biggest and most stable energy sources. That would make them invaluable to the type of civilization that needs huge amounts of power, such as a Type II Kardashev civilization. But to harness all of that power, the civilization would have to encircle the entire black hole with something that could capture the power it is emitting.
One potential solution would be a Dyson sphere—a type of stellar mega-engineering project that encapsulates an entire star (or, in this case, a black hole) in an artificial sheath that captures all of the energy the object at its center emits. But even if it was able to capture all of the energy the black hole emits, the sphere itself would still suffer from heat loss. And that heat loss would make it visible to us, according to new research published by an international team led by researchers at the National Tsing Hua University in Taiwan.

Obviously, no such structure has yet been detected. Still, the paper proves that it is possible to do so, despite no visible light making it past the sphere's surface and a black hole's reputation for being light sinks rather than light sources. To understand how we would detect such a system, first, it would be helpful to understand what that system would be designed to do.
The authors study six different energy sources that a potential Dyson sphere could collect around a black hole. They are the omnipresent cosmic microwave background radiation (which would be washing over the sphere no matter where it was placed), the black hole's Hawking radiation, its accretion disk, its Bondi accretion, its corona, and its relativistic jets.
Some of these energy sources are much more high-powered than others, with the energy from the black hole's accretion disk leading the pack in terms of potential energy captures. Other types of energy would require completely different engineering challenges, such as capturing the kinetic energy of the relativistic jets that shoot out from the black hole's poles. Size obviously plays a large factor in how much energy these black holes emit. The authors primarily focus on stellar-mass black holes as a good point of comparison against other potential energy sources. At that size, the accretion disk alone would provide hundreds of times the energy output of a main-sequence star.
