Scientists are always challenged to think outside the box, but when it came to looking for possible signs of Extra-Terrestrial Intelligence (ETI), it was even harder. One conclusion that scientists came upon was that many alien civilizations would be more technologically advanced than humanity since they might be older than us. People part of the Search for the Extra-Terrestrial Intelligence (SETI) have to consider that the extraterrestrials might be more advanced.
One radical idea would be that spacefaring alien civilizations could harness radiation emitted from black holes (Hawking radiation) to generate the power they need for their spacecraft. Louis Crane decided to build on this, and as a mathematician at Kansas State University (KSU), the researcher recently authored a study that suggests evidence of spacecraft powered by tiny artificial black holes could be found by using gamma telescopes.

“Searching for Extraterrestrial Civilizations Using Gamma-Ray Telescopes,” as the new study was called, is now available online. Dr. Crane had published another paper before on the subject which was co-authored by a physics grad student with KSU, Shawn Westmoreland, titled “Are Black Hole Spacecraft Possible?” and published ten years ago.
Westmoreland and Crane explored in the first paper the possibility of using the Hawking radiation emitted by an artificial black hole. According to them, there would be one issue regarding this, and that is the quantum gravity effects (which are currently unknown). Crane, in her most recent paper, described how the resulting gamma-rays such a system would produce could aid in the search for alien civilizations. This way, the researchers took things a step further.
The first black hole-powered spacecraft appeared for the first time in this 1975 novel, Imperial Earth, which was written by a famed science fiction author Arthur C. Clarke. Charles Sheffield presented a similar idea in his 1978 short story, “Killing Vector.” Both authors of the new study described how these advanced alien civilizations could get the energy they need from rotating black holes.
