The Problem With Quantum Gravity (ft. Eric Weinstein)

💥 Join my mailing list to win a meteorite: briankeating.com/yt Will Eric Weinstein’s Geometric Unity Survive the Rubin Revolution? Can Geometric Unity solve the deepest mysteries of the universe—or will it be challenged by a new wave of precision cosmology from experiments like DESI and the Vera Rubin Observatory? Eric Weinstein proposes that the cosmological constant isn’t constant—a claim now being tested by experiments like DESI and the groundbreaking Rubin survey. With Rubin rewriting astronomy in real time, are we witnessing the beginning of the end for the Lambda-CDM model? 🎥 Watch my full Rubin interview here: First Data from Vera Rubin Observatory Rewrites Astronomy This video features Eric’s 2025 UCSD lecture where he updates his theory before a live audience of physicists. We cover torsion, spinors, unification, and why experimental data—especially from Rubin—may now make or break the theory. ⸻ Timestamps: 00:00 Intro 01:58 Cosmological sector and geometric unity 03:57 The Poincaré group 08:31 Quantum gravity and the standard model 14:41 Torsion and gauge invariance 28:13 Spinor group and 14-dimensional space 38:24 Grand unification and spinors 42:34 The Higgs is an illusion 50:08 Outro 📢 Don’t miss Sean Carroll debating Eric on Piers Morgan ⸻ Want more on the Rubin Observatory and how it could reshape physics? ➡️ Watch: First Data from Rubin Observatory ➡️ Subscribe: DrBrianKeating ➡️ Newsletter: briankeating.com/list ⸻ More on Eric: 🌐 ericweinstein.org 🎙️ The Portal Podcast — Into the Impossible with Brian Keating is a podcast for those seeking the unknown edges of science, from unification theories to cosmic surveys reshaping what we know. #IntoTheImpossible #BrianKeating #EricWeinstein #VeraRubin #GeometricUnity #DarkEnergy #DESI #PhysicsPodcast ⸻ Let me know if you want a Rubin mention CTA added to pinned comments or mid-video cards.
