How are recent DESI 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 none other than 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 discuss his fascinating theory, the future of physics and academia, and much more.

Eric is an investor, financial executive, and host of The Portal. He coined the term Intellectual Dark Web to refer to an informal group of pundits. Eric is a vocal critic of modern academic hierarchies and advocates for advances in scientific theory over an emphasis on experimental results. He proposed a new unified theory of physics in 2013 and has been an active member of the physics community since then.
