The third cosmological paradigm

TL;DR

This paper discusses the evolution of cosmological paradigms, focusing on the limitations of the hot big-bang and $ ext{Lambda}$CDM models, and explores the aspirations and initiation of a potential third paradigm in cosmology.

Contribution

It provides a conceptual overview of the third cosmological paradigm, highlighting its goals, challenges, and the historical context of its development.

Findings

Analysis of the hot big-bang and $ ext{Lambda}$CDM models

Discussion of issues and aspirations for a new paradigm

Historical overview of collaborations with Frank Wilczek

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.
