A numerical analysis for G(t) in a scalar tensor theory

TL;DR

This paper analyzes the evolution of Newton's gravitational constant within a scalar tensor theory over the past billion years, using parameters relevant to the current universe.

Contribution

It provides a numerical analysis of G(t) in scalar tensor theories with parameters applicable to the present universe.

Findings

G(t) evolution over the last billion years is characterized.

Scalar tensor theory parameters influence G(t) behavior.

Results support scalar tensor models as viable alternatives to general relativity.

Abstract

We calculated the evolution of the Newton gravitational in a scalar tensor theory, using parameters that holds for the present Universe. We analised the evolution from one billion of years ago.
