$\Lambda$CDM: The path forward

TL;DR

This paper reviews the current status of the $\\Lambda$CDM cosmological model, discusses recent evidence for evolving dark energy, and explores how this could lead to a better, more complete cosmological theory.

Contribution

It highlights the potential role of evolving dark energy in advancing cosmological theories beyond the current $\\Lambda$CDM paradigm.

Findings

Recent evidence suggests dark energy may be evolving over time.

The $\\Lambda$CDM model is supported by extensive data but is not considered final.

Evolving dark energy could be key to developing a more complete cosmological theory.

Abstract

The current cosmological paradigm, $\Lambda$CDM, is characterized its expansive description of the history of the Universe, its deep connections to particle physics and the large amounts of data that support it. Nonetheless, $\Lambda$CDM's critics and boosters alike agree on one thing: it is the not the final cosmological theory and they are anxious to see it replaced by something better! After reviewing some of the impactful events in cosmology since the last \Le Workshop, I focus on the role that the recent evidence for evolving dark energy may play in getting cosmology that better theory.
