The third cosmological paradigm

Abstract

I begin by briefly discussing the first two cosmological paradigms, the hot big-bang model and $\Lambda$CDM. In discussing the third paradigm, I focus on the issues it must address, what its aspirations should be, and how it might be initiated. I end with a brief history of my collaborations with Frank Wilczek.

Comments: Contribution to Quantum Connections 2021, a small post-pandemic workshop that we organize to celebrate Frank Wilczek's many interests in physics and his 70th birthday. Held in Högberga Gård, Lidingö, Sweden, 21 to 25 June 2021
