   2 giorni fa · DWs with radius larger than R ann baby become larger than the cosmological horizon H b − 1 of an inflating universe with same vacuum energy V bias as their interior, in the purple region, with H b 2 = V bias / 3 M Pl 2. They become eternally inflating baby universes detaching from the parent universe through wormholes and leaving PBHs behind ...

   22 mag 2024 · Under the as-sumption that black hole interiors are birth sites of new universes, examining the production of black holes in our universe may teach us about cosmology. Many of these considerations are contained in the the-ory of cosmological natural selection (CNS).

   14 mag 2024 · In this paper I will discuss the concept of primordial black holes, their origins, their characteristics and the current constraints. In addition I will explain that the study of black holes is of utmost interest since they may constitute portals to new physics and to quantum gravity.

   20 mag 2024 · Abstract. Primordial black holes (PBHs) generated in the early Universe are considered as one of the candidates for dark matter. To produce PBHs with sufficient abundance, the primordial scalar power spectrum needs to be enhanced to the order of 0.01.

   26 mag 2024 · If the Universe is closed, there must exist a constant and positive energy density of vacuum (cosmological constant). By analyzing the McVittie metric, we show that in the expanding Universe: the Hubble parameters at the event horizons of all centrally symmetric black holes are equal and related to the cosmological constant, black holes do not grow with the expansion of the Universe, and ...
