Slice Of Mit: Stories From Mit Presented By The Mit Alumni Association

MIT professor Alan Guth ’69, PhD ’72 pioneered the theory of cosmic inflation: a period of rapid expansion that occurred a fraction of a second after the Big Bang. And he also supports the idea that our universe is just one of many in a much larger multiverse. “What we call the Big Bang Theory is really just a theory of the aftermath of some kind of a bang,” Guth says. “And inflation is a possible answer to what propelled this expansion. It's based on the idea that gravity itself can, under some circumstances, act as a repulsive force instead of an attractive force.” Read the transcript to the lecture on the Slice of MIT blog: https://alum.mit.edu/slice/podcast-inflationary-cosmology-our-universe-part-multiverse
