BIG BOUNCE PARADIGM — LATEST NEWS

Prof. B.J. Carr has a new paper on the role of primordial black holes in the Big Bounce paradigm: https://arxiv.org/pdf/1704.02919.pdf .

This paper argues that Pre-Big Bang Black Holes could survive a Big Bounce and solve some important enigmas in cosmology.

1. “In this case the same black holes would provide the dark matter in successive cosmic cycles, …”
2. “It is known that most galactic nuclei contain supermassive black holes (SMBHs), extending from 10^6 solar mass to 10^10 solar mass and already in place by a redshift ∼ 10. However, it is hard to understand how such enormous black holes could have formed so early unless there were already large seed black holes well before galaxy formation [16]. Indeed, pregalactic SMBHs could act as condensation nuclei for galaxies through their gravitational Coulomb effect [17]. The suggestion that these seeds might be PBHs forming around 1 s after the big bang has therefore become popular.

See the above-linked paper for more discussion of this exciting new direction in cosmology.
