Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field
theories, in particular for quantum gravity. Significant progress on this program has led to a …

A possible way out of the conundrum of quantum gravity is the proposal that general
relativity (GR) emerges from an underlying microscopic description. Despite recent interest …

It is well known that General Relativity cannot be considered under the standard of a
perturbatively renormalizable quantum field theory, but asymptotic safety is taken into …

The present article illustrates a method of generating exact solution for a class of isotropic
compact objects in the context of f (R, T) theory of gravity based on a linear form of the …

The origin of elementary particle mass is considered as a function of n-valued graviton
quanta. To develop this concept we begin in a cold region of “empty space” comprised of …

The gravitational field in general relativity has a geometric description that, on one hand
avails a myriad of visual cues which aid to build physicists' intuitions on the nature of space …

In the first part of the article, I illustrate and assess instances of non-empirical robustness
analysis as they occur within and across different theories of quantum gravity. The …

A new satellite-based experiment in the field of gravitation, SaToR-G, is presented. It aims to
compare the predictions of different theories of gravitation in the limit of weak-field and slow …

Quantum gravity is the solution ascribed to rendering the geometric description of classical
gravity, in any dimensions, completely consistent with principles of quantum theory. The …
