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.”
