DESI results, the cosmological constant, and the current state of fundamental theoretical physics was an interview with Eric Weinstein hosted by Dr. Brian Keating on Into the Impossible.

Description

How are recent DESI and Vera Rubin Observatory’s experimental results challenging the traditional view of dark energy as a fixed cosmological constant? Are foundational assumptions in Einstein’s general relativity limiting progress in theoretical physics? And how do tensions in cosmological measurements, like the Hubble constant discrepancy, reflect deeper issues in physics?

In this episode, we’ll explore these fundamental questions with Eric Weinstein. Eric is one of the most revered thinkers of our generation. Though not an academic physicist, he proposed a unified theory of physics in 2013, which is supposed to have the potential to explain phenomena that string theory cannot. In a lecture held live at UCSD in April 2025 at the prestigious Astrophysics and Cosmology Seminar, Eric presented an update to his groundbreaking theory. Today, we’ll discuss his fascinating theory, the future of physics and academia, and much more.
