Nice surprise - the TIFR Cosmology and Astroparticle Physics group hadn't posted any State of the Universe seminars since early 2025, but today they posted their videos since then A couple video links currently aren't working but it's likely the updates are still in process & will be available soon

Another useful tool to identify/probe highlights & get timestamps in 1 or more yt videos is gistr.so. Like NotebookLM, can mix in PDFs & webpages along with video(s) as sources. Unlike NotebookLM, watch the video, take notes, explore topic timestamps, etc all in same browser window.

Use Case: Quickly identify what was said about :topic in list of multiple yt talk videos (e.g., at a conf), including timestamps to those segments Tip: Use google's NotebookLM, add talk urls to a notebook, then ask your questions. The AI uses the transcripts as source to provide the output.

Dillon Brout gave the first public talk on this new paper and the H0 Distance Network today at the CfA ITC luncheon There were 3 talks at the lunch, this is a direct link to the start of Dillon's talk: www.youtube.com/watch?v=8nzV... #cosmology

#Cosmology The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision The baseline result is H0=73.50+/-0.81 km/s/Mpc. by the H0DN Collaboration: Stefano Casertano, et al (incl. @styrofoamplates.bsky.social) arxiv.org/abs/2510.23823 🧪

This is Figure 1 of the paper, a conceptual overview of the Local Distance Network, a many routes approach, featuring what looks like a metro map with routes converging on H0.

Dragan Huterer's DESI 3-Year Analysis talk yesterday at EuCAPT Virtual Colloquium cds.cern.ch/record/2945960 A little teaser at 43:27: Are the LCDM tension & Hubble tension related? His take is no, they're different, from segment "5 facts about hints for DDE (and Hubble tension)" starting 38:26

A slide from Dragan Huterer's talk where his take is that the LCDM tension and Hubble tension are different: "No apparent relationship (afaik)". One factor he mentions on the slide is that the Hubble tension gets worse in the w0waCDM model.
