Dr. D. Roest, Theoretical Physics, University of Groningen: Cosmic challenges for quantum gravity
|09 February 2012||FWN-Building 5111.0080, Nijenborgh 4, 9747 AG, Groningen|
|Speaker:||Dr. Diederik Roest|
|Affiliation:||Theoretical Physics, University of Groningen|
|Title:||Cosmic challenges for quantum gravity|
|Start:||16.00 (Doors open and coffee available at 15.30)|
In this colloquium we aim to provide a pedagogical introduction to the field of string cosmology, which lies at the intersection of physics, astronomy and mathematics. During the last decades there has been an extraordinary improvement in our understanding of the Universe at large. The resulting picture is both very simple and surprising, and poses a number of interesting challenges for fundamental physics. An example of these is the period of inflation in the very early Universe, which is now coming into observational focus. As inflation has taken place at very high energies, this is an excellent viewpoint to test our ideas of physics at the Planck scale, where quantum gravity starts to become important. An example of such a theory is string theory. We will demonstrate how inflation can arise in string theory, and discuss an example of how one can extract observable quantities from such constructions.
