The Doom of Spacetime
Why It Must Dissolve Into More Fundamental Structures

2384th Meeting Abstract

About the Lecture:

Space-time and Quantum Mechanics are the pillars of our modern understanding of fundamental physics. However, there are storm clouds on the horizon indicating that these principles are approximate and must be replaced with something deeper. The union of quantum mechanics and gravity strongly suggests that "space-time is doomed", and there are related indications of fundamental limitations to quantum mechanics in both the early and late universe. This talk will review these paradoxes and describe indications for a new picture where space-time and quantum mechanics will be seen to emerge hand-in-hand from more primitive principles, making contact with new areas of mathematics. The talk will present a concrete example of how these ideas work in the context of particle collision experiments of the sort performed at the Large Hadron Collider".

About the Speaker

Nima Arkani-Hamed is a world-renowned theoretical physicist with wide-ranging interests in fundamental physics, from high-energy physics and string theory to cosmology and collider physics. He has made ground breaking contributions in several areas of fundamental physics and is considered one of the most important theoretical physicists working today. He is a tireless educator and an entertaining and highly informative speaker with a unique ability to communicate complex theoretical ideas. Nima earned a BS in mathematics and physics at the University of Toronto and a PhD in physics at UC Berkeley, for work on supersymmetry and flavor physics. After his doctoral studies, Nima went to the SLAC National Accelerator Laboratory at Stanford University where he established an enduring collaboration with Savas Dimopoulos developing theories of fundamental physics involving large extra dimensions. He then joined the physics faculty at UC Berkeley. When he visited Harvard University, on a leave from Berkeley, he began working with Howard Georgi and Andrew Cohen on the idea of emergent extra dimensions ("dimensional deconstruction"), leading to the development of little Higgs theories. He joined Harvard as a Professor of Physics continue this work and then joined the Institute for Advanced Study in Princeton, where he currently is Professor of Physics. Concurrently, NIMA is an A.D. White Professor-at-Large at Cornell University Among many honors and awards, Nima is the recipient of the Phi Beta Kappa award for teaching excellence at Harvard, The Sackler Prize from Tel Aviv University, The Gribov Medal of the European Physical Society, the INFN-Pisa Gamberini prize and Packard and Sloan Fellowships. Nima is a Fellow of the American Academy of Arts and Sciences, Delivered the Messenger lectures at Cornell University, and is the inaugural awardee of the Fundamental Physics Prize. He also is one of the physicists featured in the award-winning documentary film "Particle Fever".
