In this letter, dual nature of the Ricciscalar is also obtained from a gravitational action where R2 andR3 terms dominate the Einsteinu2013Hilbert Lagrangian in thegravitational action. Cosmological models are derived using dual roleof the Ricci scalar. In an expanding model of the universe, ...

A simulation created by researchers at the Massachusetts Institute of Technology is the most detailed model of the early universe to date. Thesan, named after the Etruscan goddess of the dawn, shows the developing universe through time by combining models of galaxy formation with an algorit...

A unified description of the early evolution of the universe is given in which an inflationary period is followed by a radiation dominated phase. Comparing the dynamics of the model with those models endowed with matter creation or vacuum energy decay, allows us to establish the time dependence ...

Footnote 1 Therefore, early universe cosmology continues to be an exciting research area. Despite this big progress, several models of the early universe are still allowed and we have only a partial understanding of how the universe initially expanded and evolved. Such large ambiguity can be ...
