WFU Physics Colloquium

TITLE: String Theory in the Universe

SPEAKER: Dr. Andrew Frey ,

TIME: Thursday Oct. 8, 2009 at 4:00 PM

PLACE: Room 101 in Olin Physical Laboratory

The origin of physical constants and cosmological parameters, like particle masses and Einstein's famous cosmological constant, is one of the great mysteries of fundamental physics. I will discuss a remarkable possible answer that has come out of string theory in this decade. I will give a brief overview of some basics of string theory, describe new ideas related to the extra dimensions of string theory, and explain how these ideas can transform our conception of our universe and what this new picture could mean about the physical constants.
