Two restrictions in the theories that include and varying with time
Màrius Josep Fullana i Alfonso, Antonio Alfonso-Faus
Much work has been done taking into account the possibility that the gravitational {\it constant} may vary with cosmological time (or with the cosmological scale factor $a(…
Fundamental Principle of Information-to-Energy Conversion
Antonio Alfonso-Faus
The equivalence of 1 bit of information to entropy was given by Landauer in 1961 as kln2, k the Boltzmann constant. Erasing information implies heat dissipation and the energy of 1…
Bekenstein and the Holographic Principle: Upper bounds for Entropy
Antonio Alfonso-Faus, Màrius Josep Fullana i Alfonso
Using the Bekenstein upper bound for the ratio of the entropy of any bounded system, with energy and effective size , to its energy i.e. …
Seeable universe and its accelerated expansion: an observational test
Antonio Alfonso-Faus, Màrius Josep Fullana i Alfonso
From the equivalence principle, one gets the strength of the gravitational effect of a mass on the metric at position r from it. It is proportional to the dimensionless paramet…
Expanding versus non expanding universe
Antonio Alfonso-Faus
In cosmology the number of scientists using the framework of an expanding universe is very high. This model, the big-bang, is now overwhelmingly present in almost all aspects of so…
Underpinning the universe: its scales, holography and fractality
Antonio Alfonso-Faus, Marius Josep Fullana i Alfonso
We expand on the general concept of a universe. We identify physics as a unit applied to a universe. Then we generalize the concept of a quantum black hole, and apply it to the uni…
