[1] for early histories of bouncing cosmology).

WebOct 12, 2024 · In this work we demonstrate that wormholes can in principle be naturally created during the cosmological bounce without the need for the exotic matter or any kind of additional modifications of the gravitational sector, apart from the one enabling the cosmological bounce. WebA bounce cosmology in f (R) cosmological settings was reported in , where it was observed that the bouncing point is characterized by a type-IV singularity. In another interesting study, Odintsov and Oikonomou [ 50 ] provided an f ( R ) gravity description of a Λ CDM bouncing model without depending on any matter fluid or cosmological constant. murco cranbrook
