For 10 points, name this theory proposed by Alan Guth which proposes a brief period of very rapid expansion in the early universe.
Borde, Vilenkin and another scientist name a theorem that allows this process to apparently violate the weak energy condition by having a boundary at a finite beginning of time. It was originally posited that the Higgs field was the driving force behind this process but it is now though to be driven by a scalar field that may not have a zero energy state.  Uniformity of regions separated by light-time greater than the age of the universe and the closeness of the universe density to the critical value were the main reasons for positing it, and this process occurred from 10^-36 and 10^-32 seconds after the Big Bang.
