Today I delivered a CosmoVerse seminar by the title of Seven hints that early-time new physics alone is not sufficient to solve the Hubble tension, no surprise focused on my seven hints paper (slides here). The seminar was recorded and posted on YouTube, here is the link. A long and stimulating discussion followed, with several very interesting questions and comments from experts in the field, including Adam Riess, Vivian Poulin, and Leandros Perivolaropoulos. For other videos in this seminar series, check out the CosmoVerse YouTube channel. The next seminar from Stefano Anselmi is one which promises to be very interesting!
