Scientists have increased the before in the theoretical spheres of Dyson with a proposal of alien civilizations that build colossal megructures in the black holes of the stellar mass, pushing the power of energy harvest beyond what could be possible with only one Traditional dyson sphere.
In a new study published in the monthly announcements of the Royal Astronomical Society, researchers at the National University of Tsing Hua (NTHU) of Taiwan, dig in the production of energy from a black hole of stellar mass and found that the energy captured would be immense and in danger the amount. of energy captured by his own sun.
“An acrection album, a crown and relativistic aircraft could be possible energy stations for a type II civilization”, write the researchers. “Our results suggest that for a black stellar mass hole, even in a low relationship in Eddington, the accretion disc could provide hundreds of times more bright than a main sequence star.”
A type II civilization refers to the scale of Kardashev, a form of astrobiologists and cosmologists to classify the potential energy available for extraterrestrial intelligences.
Originally, the scale numbered from i to III, with type I being a civilization capable of taking advantage of all the energy of its domestic planet (humanity is not yet close to this stage). Type II civilizations would be able to take advantage of all the energy produced by their host star, with type III that can take advantage of all the energy of a galaxy.
The issue seems almost consigned to science fiction, but it is important when talking about the search for extraterrestrial intelligence (SETI). Although it focused predominantly in radio signals produced by an alien civilization, the problem becomes what happens if an extraterrestrial civilization is not transmitting it for reasons of self-service (that is, you can not come and invade what is not there ).
That problem was what Freeman Freeman Dyson postulated in 1960 that a sufficiently advanced alien race would reach the point where his energy needs exceeded what his planet was capable of supplying.
Then they would move themselves to take advantage of the energy of their guest star more directly by building platforms around their star in a form of biosphere that would absorb most of the energy of the star.
If such a megructure could be built, the life of the star of our perspective would significantly reduce, but it would illuminate as infrared Christmas lights. Even when this advanced alien civilization absorbed all that energy, they could not avoid purging excess heat in space, so that they do not melt their completely melted platforms.
While Dyson was not suggesting anything near what we now think like a dyson sphere, where a star is essentially locked in an artificial construct like a kind of star mate of Matryoshka, the idea of something along these lines has Captured the imagination of the imagination of these lines. The public and cosmologists alike.
Now, NTHU researchers have imagined that the capture of the energy of a black staring mass hole could provide up to five times the amount of energy captured by a main sequence star, and could even be more visible as a result, even using the Current telescopes.
Analysis: it is fascinating to consider, but how plausible this is?
To begin with, it is difficult to imagine how even a type I civilization would look like. We are talking about a civilization that could take advantage of the power of earthquakes, volcanoes, hurricanes and even the energy production of the Earth’s nucleus all at once. We are in hundreds of years of that feat if something is possible.
