These black holes may threaten to swallow anything that gets too close, according to the latest study. But the good news is that our planet is safe. The closest rogue black hole should reside thousands of light-years away. Astronomers are eager to locate them though, for the clues they will provide to the formation of the Milky Way. “These black holes are relics of the Milky Way’s past,” said Avi Loeb, Harvard-Smithsonian Centre for Astrophysics, the study co-author. “You could say that we are archaeologists studying those relics to learn about our galaxy’s history and the formation history of black holes in the early universe.” According to theory, rogue black holes originally lurked at the centres of tiny, low-mass galaxies. Over billions of years, those dwarf galaxies smashed to
