Inflationary Cosmology
7:30 p.m., Tuesday, April 19, Gheens Science Hall and Rauch Planetarium
Our universe could be part of an infinite set of universes — a multiverse — of “pocket universes” with different physical properties. Massachusetts Institute of Technology physicist Alan Guth will talk about this possibility in “Inflationary Cosmology: Is Our Universe Part of a Multiverse?” Guth wrote the book “The Inflationary Universe: The Quest for a New Theory of Cosmic Origins” about his variation of the big-bang theory. Presented by the physics and astronomy department, this talk is the third Andrew Chamblin memorial lecture. The annual lecture honors the late UofL faculty member and theoretical physicist for whom it is named. More information
