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,…
Testing Lorentz symmetry violation with an invariant minimum speed
Cláudio Nassif, A. C. Amaro de Faria, Rodrigo Francisco dos Santos
This work presents an experimental test of Lorentz invariance violation in the infrared (IR) regime by means of an invariant minimum speed in the spacetime and its effects on the t…
Connection between Symmetrical Special Relativity and the Gravitational Bose Einstein Condensate of a Gravastar/Dark Energy Star: Are there singularities in spacetime like black holes?
Claudio Nassif, Rodrigo Francisco do Santos
We aim to search for a connection between an invariant minimum speed that breaks down the Lorentz symmetry and the Gravitational Bose Einstein Condensate (GBEC), which is the centr…
Unruh effect as foundation of universal gravitation within the cosmological scenario
Claudio Nassif, A. C. Amaro de Faria
We aim to build a simple model of a gas with temperature () in thermal equilibrium with a black-body that plays the role of the adiabatically expanding universe, so that each pa…
An explanation for the tiny value of the cosmological constant and the low vacuum energy density
Cláudio Nassif
The paper aims to provide an explanation for the tiny value of the cosmological constant and the low vacuum energy density to represent the dark energy. To accomplish this, we will…
On the electrodynamics of moving particles in a quasi flat spacetime with Lorentz violation and its cosmological implications
Cláudio Nassif
This research aims to develop a new approach toward a consistent coupling of electromagnetic and gravitational fields by using an electron that couples with a weak gravitational po…
