TED: Have we reached the end of physics? | Harry Cliff

The video explores the revolutionary impact of Einstein's general relativity and quantum mechanics on our understanding of the universe. It discusses the discovery of the Higgs Boson at CERN and its significance, the mysterious nature of dark energy, and the challenges posed by string theory and the multiverse concept. The video concludes with a discussion on the future of physics and the role of the Large Hadron Collider in advancing our knowledge.
