HIGHLIGHTS
- who: Armando Vega-Colon and Jeffery A. Secrest from the Department of Physics and Astronomy, Armstrong Campus, Georgia Southern University, Savannah, USA have published the article: A Study in the Variation of G, in the Journal: (JOURNAL)
- what: In this study, the variation of the gravitational parameter is examined not on a local scale but on a cosmological scale. All HT cosmologies under consideration in this study have a gravitational parameter that is initially negative indicating the repulsive nature of the gravity under consideration in these models.
- how: Various possible characterizations of gravitational . . .
