Exploding primordial black holes might have reshaped the early universe, and created all matter as we know it

The early universe is so far removed from our understanding of how the world works that it is difficult to describe in words. At the time, the cosmos was not filled with stars and galaxies but with a boiling soup of quarks and gluons, to which were added a few microscopic black holes, sometimes exploding like depth charges. This is the primitive universe theorized by a new article, available in pre-print on arXiv, written in any case by researchers from the Vrije Universiteit Brussel and MIT.
