My favorite article I've read covering the DESI results. Well written and a great glimpse into the human side :)

Shocking Dark Energy Findings Challenge the Standard Model of the Universe
A new map of cosmic expansion suggests that dark energy evolves over time, hinting that the universe doesn’t work the way we thought it did

🔊 New BAO analysis from the 3-year observations (DR2). Long story short, as follows.
1. DESI alone is consistent with LCDM. 👉 Boring
2. DESI and Planck have a 2.3 discrepancy in Ωm-H0rd plane. 👉Interesting.

This is starting to look believable (to me at least 😅)

*Something* is certainly going on...

Great work @desisurvey.bsky.social!

🔭👀 New results from the @desisurvey.bsky.social strengthen hints that #DarkEnergy might evolve.

A long-exposure image captures circular star trails above telescope domes illuminated in red light on a dark mountain. A golden glow on the horizon marks distant city lights. A person reaches out a tool to clean a large mirror, surrounded by an intricate framework of metal structures. DESI’s instrument, a long black cylinder supported by the metal framework of the telescope, points at the domed ceiling.
