Can geometric unity actually solve the deepest mysteries of our universe, or will it join the many others that have tried unsuccessfully in the past to create a new unified theory?

Eric Weinstein 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’re sharing his fascinating lecture with you! 

Eric is an investor, financial executive, and host of The Portal. He and his brother, Bret Weinstein, 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.
