You Had Me At “Black Hole Power Sucking Aliens”

Aliens could be sucking power from black holes — and that could be how we’d spot the extraterrestrials, scientists say.

This energy-harvesting technology could leave traces just outside a spinning black hole’s event horizon — the boundary beyond which a black hole’s gravity becomes too strong for matter and energy to escape. And the process could explain at least some flares of plasma, a white-hot form of charged gas, that scientists have already detected near these massive disruptions in time and space. a new study published Jan. 13 in the journal Physical Review D proposes.

And while it’s only a science-fiction idea at the moment — the nearest black hole to us is thought to be more than 1,000 light-years away, which is too far to be reached in many human lifetimes — if astrophysicists could ever work out a method of tapping these cosmic behemoths, rotating black holes could become a near-limitless source of energy for a technologically advanced civilization.

The co-author of the study, astrophysicist Luca Comisso of Columbia University in New York, said the next step will be to figure out what deliberate extraction energy from a black hole might look like to distant observers.
