Hunting for Cosmic Stasis Within the Cosmological Timeline

Download to your calendar using vCal

If you have a question about this talk, please contact Gonzalo Villa .

Cosmic Stasis is an intriguing phenomenon that may arise in a large class of beyond-the-standard-modelĀ theories of the early universe, in which the universe is made of a peculiarly stable admixture of co-existing perfect fluids on long cosmological time scales. In this talk, I will review the theoretical foundationĀ of this new paradigm and discuss how it may manifest itself in a variety of cosmological observables, spreading from the primordial spectrum of scalar perturbations, the evolution of large-scale structures in the post-inflationary universe, the dynamics of big-bang nucleosynthesis, or evenĀ the varying equation of state of dark energy today.

This talk is part of the Cosmology Lunch series.
