90% Probability of Primordial Black Hole Explosion Within Decade

Physicists now estimate there is up to a 90% chance of witnessing a primordial black hole (PBH) explode within the next decade, a phenomenon that was previously thought to occur only once every 100,000 years. These PBHs are tiny black holes theorized to have formed shortly after the Big Bang, distinct from the larger stellar black holes formed from dying stars. The explosions would result from Hawking radiation, a process proposed by Stephen Hawking, where black holes lose mass by emitting particles until they reach a catastrophic collapse. Recent research introduces the idea that PBHs might carry a small dark electric charge, involving hypothetical "dark electrons," which could stabilize them longer and increase the likelihood of observing their final explosions. Detecting such an event would not only confirm Hawking's theory but also offer insights into the fundamental particles comprising the universe and potentially shed light on the nature of dark matter. Furthermore, a high-energy neutrino detected by the KM3NeT observatory could be linked to the explosive evaporation of a nearby primordial black hole, suggesting an observational path to understanding these enigmatic cosmic objects.
