   5 giorni fa · It is believed that these early-formed black holes could explain the missing mass not accounted for by visible matter. However, recent studies using quantum field theory suggest that PBHs might be scarcer than previously thought, challenging their viability as dark matter candidates.

   5 giorni fa · In the early universe, before even the basic elements had formed, pockets of ultradense, primordial matter could have accumulated and collapsed to form microscopic black holes. These black holes could have been so dense as to squeeze the mass of an asteroid into a region as small as a single atom.

   2 giorni fa · In this paper, we are interested in cases describing black-hole solutions to quadratic gravity in the vicinity of a horizon. Thus in the rest of the paper, we will focus on the classes [0,1] and [0,2], for which H= 0 at r. 0= r. h(14), corresponding to non-extremal/extremal horizon, respectively.
