Black holes from before the Big Bang may still exist today as “cosmic fossils” | Science News

Gaztanaga proposes a new dark matter mechanism in which relic black holes arise from a pre-big-bounce collapse stage.

New research by Professor Enrique Gaztanaga of the University of Portsmouth and the Institute of Space Sciences in Barcelona suggests that some black holes formed before the Big Bang and survived the cosmic ‘bounce’, potentially explaining dark matter, the gravitational wave background, and the early growth of supermassive black holes and galaxies. Gaztanaga proposes a … Read more
