Cosmological background solutions and cosmological backreactions

open access: yes, 2009
The cosmological backreaction proposal, which attempts to account for observations without a primary dark energy source in the stress-energy tensor, has been developed and discussed by means of different approaches.

Faith and Works … Or Works and Faith? A Performative Faith in Samoan Churches

open access: yesReligions
Christianity is the main religion in the Pacific Islands, and what is unique about Christianity in the Pacific is that religion cannot be separated from everyday life experiences.

Leading loop effects in pseudoscalar-Higgs portal dark matter

open access: yesJournal of High Energy Physics, 2019
We examine a model with a fermionic dark matter candidate having pseudoscalar interaction with the standard model particles where its direct detection elastic scattering cross section at tree level is highly suppressed. We then calculate analytically the

The Existence and Effect of Dark Energy Redshift on Cosmological Age

open access: yesAdvances in Astronomy, 2020
A derivation of Cosmological Age explicitly constrained by Cosmic Microwave Background Radiation (CMBR) is presented, demonstrating that the correct value of Cosmological Age is equal to the Hubble Age. It is shown that utilizing “z = 0” for Cosmological

Quantum Potential and Cosmological Singularities

open access: yes, 1997
We apply the de Broglie-Bohm interpretation to the Wheeler-DeWitt equation for the quantum FRW cosmological model with a minimal massless scalar field. We find that the quantum FRW cosmological model has quantum potential dominated solutions that avoid ...

Cosmological Entanglement

open access: yesInternational Journal of Theoretical Physics, 2010
We investigate the connection between the entanglement generated by expanding universe and the cosmological parameters. We show that the faster the universe expands and the larger the total volume results the higher degree of entanglement.

Apparent versus true value of the cosmological constant

open access: yes, 2012
Supernovae observations strongly support the presence of a cosmological constant, but its value, which we will call apparent, is normally determined assuming that the universe can be accurately described by a homogeneous model.

Quantum cosmology

open access: yesZeitschrift für Naturforschung A, 2022
AbstractWe give an introduction into quantum cosmology with emphasis on its conceptual parts. After a general motivation, we review the formalism of canonical quantum gravity on which discussions of quantum cosmology are usually based. We then present the minisuperspace Wheeler–DeWitt equation and elaborate on the problem of time, the imposition of ...
