Hawking radiation is radiation released outside a black hole's event horizon due to quantum effects according to a model developed by Stephen Hawking in 1974. This black-body radiation was not predict

In cosmology, primordial black holes are hypothetical black holes that formed soon after the Big Bang. In the inflationary era and early radiation-dominated universe, extremely dense pockets of subato

…radiation than larger black holes and should dissipate faster per their mass. Consequently, if small black holes exist, as permitted by the hypothesis of primordial black holes, they will lose mass more rapidly as they shrink, leading to a final cataclysm of high energy radiation alone. Such radiation bursts have not yet been…
Researchers using the James Webb Space Telescope in November 2025 confirmed an actively growing supermassive black hole within a "little red dot" galaxy named CANUCS-LRD-z8.6, just 570 million years after the Big Bang.
