“Yes, it was a crazy idea,” said Marc Kamionkowski, Johns Hopkins University whose group came out with one of the many eye-catching papers tha
Alas, the flirtation with primordial black holes soured in 2017, after a paper by Yacine Ali-Haïmoud, an astrophysicist at New York University who had previously been on the optimistic Kamionkowski team, examined how this type of black hole should affect LIGO’s detection rate. He calculated
But many lost hope. The argument was so damning that Kamionkowski said it quenched his own interest in the hypothesis
Karsten Jedamzik, a cosmologist at the University of Montpellier, showed how a large population of primordial black holes could result in collisions that perfectly match what LIGO observes.
Ali-Haïmoud, who has continued to play with the primordial black hole idea in subsequent papers too. “It would mean that in fact they could be all the dark matter.”
“It’s exciting,” said Christian Byrnes, a cosmologist at the University of Sussex who helped inspire some of Jedamzik’s arguments. “He’s gone further than anyone has gone before.”
Theorists couldn’t say how massive primordial black holes should be, or how many to expect.
The Fermion Repelling Horizon or trapped space surface (Penrose) by Axion space compression horizon, or according to Vuyk: by an Axion collider horizon, creating fermion pairs and plasma (pos. quarks and electrons)
A NEW DM BH BIG BANG: see: an old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter. It fell out of favor for decades. NOW the Penrose trapped vacuum horizon (above) in combination with Fermion repelling of Q-FFF THEORY , IT SEEMS THE RIGHT SOLUTION for a mass less string knot based nucleus for all black holes even the Big Crunch leading to a cyclic universe (symmetric multiverse).
