Physics and Astronomy Colloquium: “The String Landscape and the Swampland"

Cumrun Vafa (Harvard University)
- | NOTE: FROM NOW ON, ALL COLLOQUIA WILL BEGIN AT 3:00 PM!

String theory landscape of vacua point to new consistency conditions that a quantum gravitational system must satisfy.  There are only a small number of quantum field theories that satisfy these conditions and all the rest belong to the `Swampland' which cannot be consistently coupled to gravity.  In this talk I review some of these conditions and their implications for cosmology and particle physics.
