Primordial Black Holes
Primordial black holes are hypothesized to have formed in the early universe, shortly after the Big Bang. These black holes are thought to have originated from the gravitational collapse of high-density regions, such as fluctuations in the density of matter or the collapse of cosmic strings. Primordial black holes are distinct from stellar black holes, as they are believed to be much smaller in mass, ranging from microscopic sizes to several solar masses. Their existence could provide insights into the early universe, dark matter, and the nature of gravity.
