Dark matter hasn’t been a matter easily explained in our Universe. However, we have long accepted Stephen Hawking’s theory that this universal enigma is formed from primordial black holes. However, a new study from the University of Lisbon in Portugal and the Harvard-Smithsonian Center for Astrophysics says that’s not so. They analyzed what would happen if a primordial black hole passed through neutron stars. They found that, despite the small mass of the black hole, it would destroy the neutron star. And due to the prevalence of neutron stars in our own galaxy, the very presence of these stars show that primordial black holes could not be the primary constituent of dark matter.
