In a new study, scientists have suggested that advanced alien civilisations may have been migrating near miniature black holes to fulfil the energy needs of their home planets.
There is a possibility that these aliens are capturing the unlimited energy around the black holes and taking it back to their planets.
In the study, Harvard astrophysicist Avi Loeb has suggested that these black hole “moons” can be a sign of advanced aliens and can help scientists in understanding the life outside the Solar System.
It is known that black holes emit photons and large sub-atomic particles which are collectively called Hawking Radiation, named after physicist Stephen Hawking.
Hawking in 1974 suggested that a black hole is able to shine on its own without the need of an external fuel supply.
The new study was published in the journal Research Notes of the American Astronomical Society and it took into consideration the possibility that technologically advanced alien civilisation may have been creating and tapping their own “mini” black hole for fulfilling their energy needs.
How aliens are extracting energy from black hole ‘moons’?
The momentum of the rotating disc of matter which is around the black hole is likely to have been utilised by the aliens to produce energy in this system, suggested scientists.
According to Dr Loeb, another way could have been to feed matter in the black hole and create Hawking Radiation.
The Harvard scientist suggested that such kinds of black holes should weigh only 100,000 tonnes.
Dr Loeb said that in exchange for the matter thrown inside black holes, they can provide “an endless supply of power”.

“This black hole system is the most efficient engine I ever thought about. The fuel is converted to energy with perfect efficiency of 100 per cent as the mass falling into the black hole is ultimately coming out as Hawking Radiation,” Dr Loeb said.
“The only other method for converting mass to radiation with this efficiency is matter-antimatter annihilation,” added the Harvard researcher.
Such black hole systems have the capacity to power roaming rogue planets which do not have a star and can otherwise become uninhabitable and frozen.
