This is the follow-up to the Leonard Susskind video on string theory. In this segment Susskind explains how it is that string theory allows for a near infinite number of possible universes, a fact that some advocates of the multiverse idea have latched on to to justify their belief that these other universes actually do exist. In fact, Susskind himself seems in the video to embrace both the weak anthropic principle and the multiverse hypothesis:
Susskind once admitted that the only alternatives are a multiverse or God. Nothing else can explain the breath-taking precision of the cosmic fine-tuning. I wonder what he'll do if string theory is ever shown to be unworkable.
