A Radical Solution to the Hubble Tension Problem

Understand

The Hubble tension has proven to be stubbornly persistent, despite widespread efforts to relax it.

• As a possible resolution of this problem we propose a radical alternative to the way in which cosmological models are viewed.
• Specifically, we consider building cosmological models from spaces that exhibit intrinsic symmetries, rather than as space-times with explicit symmetry.
• This change in perspective allows statistical homogeneity and isotropy to be maintained, while relaxing some strong mathematical constraints that the standard approach imposes.
