Primordial Black Holes

Primordial black holes are, in theory, tiny black holes left over from the Big Bang. No such object has yet been confirmed, but physicists and astronomers are looking for them.

When black holes and stars physically interact, it's generally not good news for the stars. Primordial black holes are so small, however, that they would pass through a star instead of gobbling it up. In passing through, it would cause something like ripples on the surface of the star, and it's those ripples that scientists want to see. By studying those ripples, they could learn about the interior of the star, and, a new study suggests, get a better handle on the nature of dark matter.
