After nearly half a century in space, the Voyager 1 spacecraft has shut down one of its last remaining scientific instruments in a desperate attempt to conserve power. NASA’s decision to power down the instruments comes just before the final “big bang” moment that mission managers hope will further extend the lives of the two … Read more

Black holes that formed before the Big Bang may still exist and continue to shape galaxies to this day.

Researchers have discovered that black holes that formed before the Big Bang may still exist today as surviving relics. These ancient objects carry mass and structure from early cosmic stages and will provide new ways to explain how galaxies formed and why invisible matter dominates them. Within this framework, relic black holes do … Read more

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
