It has been shown that the following modification of the symmetric (Gilbert) total energy–momentum tensor (EMT) density $${t^{\mu v}} \to {t^{\mu v}} - \frac{{{m^2}}}{{16\pi G}}{\tilde \varphi ^{\mu v}}$$ leads to incorrect results in basic energet

We consider a model of a scalar field with a nontrivial kinetic part (k-essence) on the background of a flat homogeneous isotropic universe in the framework of the relativistic theory of gravitation and general relativity. Such a scalar field simulat

It was shown in the frameworks of massive gravitational theories having in linear approximation mass term $${m^2}\left( {{\varphi ^{\alpha \beta }}{\varphi _{\alpha \beta }} - \frac{1}{2}{\varphi ^2}} \right)$$ in the lagrangian, that created some ti

The problem of the local Hubble flow on scales of several Mpc induced by the dark energy realized by a scalar quintessence field is considered within the framework of relativistic gravity theory (RGT). The observational Hubble Space Telescope data ar

Mach’s principle in the relativistic theory of gravity (RTG) allows preliminarily selecting all possible solutions of the theory, including cosmological ones. It is shown that Mach’s principle in the RTG with massive gravitons admits only flat an

The energy-momentum tensor for the Kerr metric is calculated within the relativistic theory of gravitation. The external gravitational energy and angular momentum of a collapsing body are found. It is concluded from the analysis of their behavior nea

We show that although the equations of the relativistic theory of gravity admit nontrivial vacuum cosmological solutions, all these solutions contradict the causality principle. The vacuum cosmological solution is therefore unique and trivial: the gr
