Black holes may have existed since the beginning of time (and could explain dark matter mystery)

The nature and origin of black holes and their role in the evolution of the universe still puzzles scientists. Now, a new study suggests that the existence of black holes from the earliest moments of the universe could explain more than one astronomical mystery. 

The new study suggests that small primordial black holes filled the early universe right after the Big Bang, acting as an accelerator of star and galaxy formation. This theory by itself is not new, as it was proposed by Stephen Hawking in 1971. In the new study, however, a team of astronomers shows how the existence of such primordial black holes neatly fills some major gaps in the current understanding of the universe.
