Are Asteroid-Mass Black Holes Hiding In The Cosmic Gamma-Ray Glow?

Exploring the Mystery of Primordial Black Holes

Black holes can form through various processes, with the most familiar being the collapse of a massive star at the end of its life cycle. However, there's another intriguing category known as primordial black holes (PBHs). These theoretical entities may have emerged right after the Big Bang, formed from matter collapsing under its own gravity. Despite extensive speculation, no direct evidence of PBHs has ever been observed.

Scientists propose that these elusive black holes could play a crucial role in explaining the universe's missing mass, often attributed to dark matter. The concept of PBHs remains a captivating area of research, inviting further exploration into their potential existence and impact on cosmic structure.
