- W4221147771 abstract "We discuss the relationship between dark matter and the entropy of the universe with the premise that dark matter exists in the form of primordial black holes (PBHs) in a hierarchy of mass tiers. The lightest tier are intermediate-mass PIMBHs within galaxies including the Milky Way. Supermassive black holes at galactic centres are in the second tier. We are led to speculate that there exists a third tier of extremely massive PBHs, more massive than entire galaxies. We discuss future observations by the Rubin Observatory and James Webb Space Telescope." @default.
