## Variations of the Gravitational Constant with Time in the Framework of the Expanding Universe

**Authors:** Mugur B. Răuţ

This paper is an attempt to find an answer in the matter of expanding universe from the time variance of the gravitational constant point of view. We took as reference the equivalent variation of the gravitational constant of a static universe and report the observational data to it. The equivalent variation of the gravitational constant of a static universe is estimated in a reference universe hypothesis. An expanding force is balanced by an attracting force and this is the basis from which we can establish a formal time variance for the gravitational constant in two cases. The first one correspond to an expanding universe, hence this case can’t be a reference for our evaluation. The second case corresponds to a static universe and it is the same as a de Sitter universe. This is the reason why this case can be a reference case. Thus the observational data smaller than our reference theoretical value, are linked to a collapsing universe and the observational data greater than the same reference value are characteristic to an expanding universe.
