Conformal Cyclic Cosmology from Varying Fundamental Constants
Konrad Marosek, Adam Balcerzak
We investigate a bimetric cosmological model in which the gravitational and matter sectors are described by distinct metrics related through a time-dependent function . This…
Conformal structure of singularities in some varying fundamental constants bimetric cosmologies
Konrad Marosek, Adam Balcerzak
In this paper, we explore the conformal structure of singularities arising from varying fundamental constants using the method of Penrose diagrams. We employ a specific type of bim…
Four direct measurements of the fine-structure constant 13 billion years ago
Michael R. Wilczynska, John K. Webb, Matthew Bainbridge +14
Observations of the redshift z=7.085 quasar J1120+0641 have been used to search for variations of the fine structure constant, alpha, over the redshift range 5.5 to 7.1. Observatio…
Doubleverse entanglement in third quantized non-minimally coupled varying constants cosmologies
Adam Balcerzak, Konrad Marosek
In this paper we consider a third quantized cosmological model with varying speed of light and varying gravitational constant both represented by non-minimally coupled scal…
Emergence of multiverse in third quantized varying constants cosmologies
Adam Balcerzak, Konrad Marosek
Although the standard cosmological model explains most of the observed phenomena it still struggles with the problem of initial singularity. An interesting scenario in which the pr…
Non-exotic conformal structure of weak exotic singularities
Mariusz P. Dabrowski, Konrad Marosek
We study the conformal structure of exotic (non-big-bang) singularity universes using the hybrid big-bang/exotic singularity/big-bang and big-rip/exotic singularity/big-rip models…
Strength of singularities in varying constants theories
Konrad Marosek, Adam Balcerzak
In this paper we consider a specific type of the bimetric theory of gravitation with the two different metrics introduced in the cosmological frame. Both metrics respect all the sy…
Cyclic multiverses
Konrad Marosek, Mariusz P. Dabrowski, Adam Balcerzak
Using the idea of regularisation of singularities due to the variability of the fundamental constants in cosmology we study the cyclic universe models. We find two models of oscill…
Standard and exotic singularities regularized by varying constants
Mariusz P. Dabrowski, Konrad Marosek, Adam Balcerzak
We review the variety of new singularities in homogeneous and isotropic FRW cosmology which differ from standard Big-Bang and Big-Crunch singularities and suggest how the nature of…
Regularizing cosmological singularities by varying physical constants
Mariusz P. Dabrowski, Konrad Marosek
Varying physical constant cosmologies were claimed to solve standard cosmological problems such as the horizon, the flatness and the -problem. In this paper, we suggest yet anot…
