"Primordial black holes should form during the first few seconds after the Big Bang. If they exist, they have some advantages over astrophysical black holes," Regan said.

Primordial black holes could be a type of dark matter called MACHOs, which stands for massive compact halo objects, because astronomers think they’re found in the halos, or outskirts, of galaxies.

Massive primordial black holes could be the long sought answer. Such large, heavy objects might also have served as the anchors around which early galaxies coalesced, another conundrum that has ...

That is, a hypothetical primordial black hole (PBH) with a horizon size no larger than a grapefruit, and with a mass 5 to 10 times that of Earth. How might it be detected?
