Seven hints that early-time new physics alone is not sufficient to solve the Hubble tension
S Vagnozzi - Universe, 2023 - mdpi.com
The Hubble tension has now grown to a level of significance which can no longer be
ignored and calls for a solution which, despite a huge number of attempts, has so far eluded …
