Easing the Hubble constant tension

In this paper, we show how a modified Friedmann equation, originating from a model of the universe built from a certain W-3 algebra, has the potential to explain the difference between the Hubble constants extracted from CMB data and from supernova data.

Automated summary

In this paper, a modified Friedmann equation derived from a W-3 algebra-based universe model is proposed to explain the discrepancy between the Hubble constants obtained from CMB data and supernova data.
