Advances of relativity theory

open access: yesPhysics Essays, 2020
Advances of relativity theory are in the replacement of the space-time model with time-invariant universal space that has a variable energy density. Every physical object with mass m and energy E is diminishing the energy density of space exactly for the amount of its energy. Lorentz factor has its origin in the variable density of universal space, we

A note on the equivalence of energy–momentum distribution for diagonal and non-diagonal models in general relativity and teleparallel gravity

open access: yesResults in Physics, 2022
In this paper, it is shown that the super-potential defined by Einstein, Landau–Lifshitz, and Bergmann–Thompson in general relativity theory and in teleparallel gravity theory are equivalent for a general diagonal space–time metric. Therefore, the energy–

An alternative way to present a relativistic Lagrangian definition

open access: yesRevista Brasileira de Ensino de Física, 2021
As long we known, the non-relativistic Lagrangian definition, L = T − U with T and U as being, respectively, kinetic and potential energy, it is not valid at the relativistic level.

Relativity Theory Refounded [PDF]

open access: yesFoundations of Science, 2017
We put forward a new view of relativity theory that makes the existence of a flow of time compatible with the four-dimensional block universe. To this end, we apply the creation-discovery view elaborated for quantum mechanics to relativity theory and in such a way that time and space become creations instead of discoveries and an underlying non ...

The Universal Theory for Multiscale Modelling of Infectious Disease Dynamics

open access: yesMathematics, 2023
The replication-transmission relativity theory, currently used to inform the development of multiscale models of infectious disease dynamics, needs a revision and extension to accommodate new basic science and clinical information about infectious ...
