Advanced alien civilisations, if they exist, could satisfy the energy needs of their home planet by migrating near miniature black holes and trapping the potentially unlimited energy around them, according to a new study.

Such black hole “moons” could be tell-tale sign of advanced aliens, and may be used to look for life outside the Solar System, Harvard astrophysicist Avi Loeb says in the study.
