Neil deGrasse Tyson on how our universe may connect to a multiverse

Astrophysicist and cosmologist Neil deGrasse Tyson, speaking with journalist Robert Krulwich during 92Y's Giants of Science series in 2007, explored one of cosmology’s biggest questions: How did the universe begin? Tyson discussed the idea that our universe may be just one “bubble” within a far larger multiverse, where countless universes could emerge and vanish over time. But this raises an even deeper mystery: if our universe had a beginning, what created the multiverse itself? According to Tyson, one possible answer is as fascinating as it is unsettling: the multiverse may have always existed. Video courtesy: The 92nd Street Y, New York
