“Given the extent of the observable universe that has yet to be mapped out, some might wonder why some physicists have introduced the concept of a multiverse into their models.  This talk will examine why some eminent physicists, such as the late Nobel laureate Steven Weinberg, have been attracted to the idea of the multiverse, and others, such as Princeton cosmologist Paul Steinhardt, have raised significant concerns.  We’ll also show how the cultural and scientific ideas of multiverses differ significantly.”
