Astronomers may soon be able to confirm the existence of a primordial black hole –gravity wells formed just moments after the Big Bang–in our Solar System with gravitational-wave experiments that will look back to a time before the formation of the first stars. “Ancient black holes would give us access to physics we would never otherwise be able to do,” wrote Dan Hooper, head of the theoretical astrophysics group at FermiLab, in an email to The Daily Galaxy. “If primordial black holes are real,’ he wrote, “they’d have potential to solve a whole host of the biggest problems in cosmology, not the least being the mystery of dark matter, considered to be the backbone to the structure of the universe.”
Did primordial Black holes –described as “the gates of hell, the end of spacetime, paradoxical, intriguing, frightening” by the Event Horizon Telescope scientists who imaged the now iconic black hole the size of our solar system at the heart of monster elliptical galaxy M87— exist during the cosmic Dark Age following the Big Bang, before the formation of the first stars?
“We are back to the standard discussions. What is dark matter? Indeed, we are running out of good options,” said Uroš Seljak, a UC Berkeley professor of physics and astronomy and BCCP co-director. “This is a challenge for future generations.”
