Our improving understanding of the cosmos points to an early epoch during which the universe expanded at a stupendous rate to create the vast amount of space we can observe. Cosmologist are now coming to believe that this “cosmic inflation” may do much more: in many versions, inflation goes on forever, generating not just our observable universe but also infinitely many such regions with similar or different properties, together forming a staggeringly complex and vast “multiverse”. Dr. Aguirre traces the genesis of this idea, explores some of its implications, and discusses how scientists are seeking ways to test this idea.
