Study Links Primordial Black Holes and Hawking Radiation

Recent studies have focused on primordial black holes (PBHs), theorized to have formed in the universe's first moments, potentially leading to detectable explosions driven by Hawking radiation. This quantum phenomenon creates particles from the vacuum near a black hole's event horizon, resulting in both the emission of radiation and the eventual evaporation of the black hole itself. Researchers suggest that if these PBH explosions can be observed, they may reveal new physics and unknown particles. Additionally, a new study highlights the necessity of Vaidya radiation for a black hole's horizon to remain stable while absorbing matter, allowing Hawking radiation to escape. This research could further our understanding of black hole dynamics and their role in the universe. The existence of PBHs remains theoretical, supported by cosmological models but lacking direct observational evidence.
