Primordial black holes are hypothetical black holes that are thought to have formed in the early universe, shortly after the Big Bang. Unlike black holes that form from the collapse of massive stars, primordial black holes are believed to have originated from the extreme density fluctuations in the early universe. These density fluctuations could have caused regions of sufficiently high density to undergo gravitational collapse, forming black holes.

Primordial black holes could have a wide range of masses, from tiny ones with masses less than the Earth's to supermassive ones with masses millions of times that of the Sun. Because they are formed in the early universe, primordial black holes could have interesting implications for cosmology, astrophysics, and even the search for dark matter.

Although there is currently no direct observational evidence for the existence of primordial black holes, their existence is still a possibility, and scientists continue to study their potential formation mechanisms and observational signatures.
