Primordial Black Holes and Dark Matter

This chapter explores the differences between primordial black holes and regular black holes, focusing on their formation in the early universe. It discusses how primordial black holes can arise from gravitational collapse without relying on stars and their potential role as candidates for dark matter. The chapter also examines the implications of quantum chromodynamics in understanding these black holes and the conditions of the early universe, emphasizing the need for further research in this area.
