Cumrun Vafa, Ph.D.Hollis Professor of Mathematicks and Natural Philosophy; Professor of Physics, Harvard University
Mathematics and Physical Sciences lectures are open to the public and are held at the Gerald D. Fischbach Auditorium at the Simons Foundation headquarters in New York City. Tea is served prior to each lecture.
Over the last few decades, string theory has emerged as a consistent, unified quantum theory of all the particles and forces. This development has led to a sharper understanding of the geometry of space and time as well as the basic physical laws that govern that geometry. String theory has also resulted in surprising predictions about our universe.
Solutions to string theory involve spaces with special mathematical properties. The study of these spaces has led to a ‘landscape’ of potentially consistent universes. The work has also led to the unexpected result that some consistent-looking universes cannot possibly exist and belong to the ’swampland.’ In this talk, Cumrun Vafa reviews some of the predictions to which this picture leads, both for the fundamental constituents of our universe as well as the ultimate fate of the cosmos.
