Dark Matter Could Be Made of Black Holes From the Beginning of Time

“Solar-mass black holes are quite mysterious, as they are not expected from conventional astrophysics,” such as the star explosions, or supernovas, that crush larger stars into black holes, study lead author, Volodymyr Takhistov of the University of California, Los Angeles, told Live Science in an email. Instead, the authors propose in the study, published February 16 in the journal Physical Review Letters, these solar mass black holes may be “primordial” black holes created during the Big Bang. Or they might have formed later when neutron stars were transmuted into black holes — either after swallowing up primordial black holes, or after absorbing certain proposed types of dark matter, the mysterious matter that exerts gravitational pull does not interact with light, Takhistov said.
