• "What Exists in the Quantum Universe by Steve Giddings"Quantum mechanics is undoubtedly one of the most successful physical theories, and seemingly all observed events respect its principles. However, will it still hold true for the Ultimate Quantum Theory? What implications does it have for questions like "What exists?", "What are observations?", and "What is the structure of quantum gravity?" Join Steve Giddings as he delves into these profound topics.
