Crack in the cosmological paradigm
Eleonora Di Valentino
TL;DR
This paper discusses how a time-dependent dark energy component could resolve discrepancies between local and primordial measurements, challenging the standard cosmological constant model.
Contribution
It proposes that a dynamic dark energy component may explain current tensions in cosmological data, offering an alternative to the cosmological constant.
Findings
Time-dependent dark energy can reconcile measurement tensions.
Challenging the cosmological constant paradigm.
Potential implications for cosmological models.
Abstract
A time-dependent dark energy component of the Universe may be able to explain tensions between local and primordial measurements of cosmological parameters, shaking current confidence in the concept of a cosmological constant.
