Episode notes

Is everything we thought we knew about the universe… wrong? Is the Lambda-CDM model nearing its breaking point? Could dark energy actually be evolving?

In this episode of Into the Impossible, I’m joined by Kyle Dawson and Daniel Green to discuss the latest data from the DESI experiment. These new results are making headlines, and rightfully so, as they hold the potential to transform our understanding of the universe completely.

Kyle Dawson, a key figure in the DESI project and professor at the University of Utah, explains the findings from DESI’s second data release. Together with Daniel Green from the University of California, San Diego, we dig into how fresh observations of dark energy, baryon acoustic oscillations (BAO), and cosmic expansion are revealing cracks in the standard model. We also break down the implications of these results and talk about the possible existence of negative neutrino masses—a topic that’s been gaining a lot of attention in the cosmology community.
