Background gravitational waves as signature of the adiabatic expansion of a black body that represents the dark universe
Cláudio Nassif Cruz, A. C. Amaro de Faria
We propose a toy model of a spherical universe made up of an exotic dark gas with temperature in thermal equilibrium with a black-body in adiabatic expansion. Each particle of…
A brief review of a modified relativity that explains cosmological constant
Cláudio Nassif Cruz, A. C. Amaro de Faria
The present review aims to show that a modified space-time with an invariant minimum speed provides a relation with Weyl geometry in the Newtonian approximation of weak-field. The…
The K-essence flow seen from the preferred frame . A scalar field theory with Landau superfluid structure
Rodrigo Francisco dos Santos, Luis Gustavo de Almeida, A. C. Amaro de Faria
We study the hypothesis of deformation of the invariance of Lorentz transformations produced by the introduction of a universal minimum velocity relative to a preferred frame. Our…
Variation of the fundamental constants over the cosmological time: veracity of Dirac's intriguing hypothesis
Cláudio Nassif, A. C. Amaro de Faria
We investigate how the universal constants, including the fine structure constant, have varied since the early universe close to the Planck energy scale (GeV) and,…
