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

…light speed. Such a high mass may place it into a proposed category of stupendously large black holes (SLABs), black holes that may have been seeded by primordial black holes with masses that may reach 100 billion M☉ or more, larger than the upper maximum limit for at least luminous accreting black holes hosted by disc…
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.
