‘Faith’ in the Multiverse?

The concept of the Multiverse is an old one, one that has been approached primarily as a matter of metaphysics or philosophy. But is it scientific? And, if it is scientific, why do so many of its most ardent supporters describe their ‘faith’ in the Multiverse?

This video explores several contrasting viewpoints, from Andrei Linde to Paul Davies as well as ways to test Eternal Inflation, one of the leading theories that predicts a Multiverse.

•Interview with Andrei Linde ““Can you really prove that it is just universe? The insistence that we have just one universe has to be proved.” The article continues: “Linde has continued to push forward his thinking about cosmic inflation, melding it with string theory, one of the leading explanations of the particles and forces underlying the laws of physics. This has further strengthened his faith in the multiverse because it provides a mechanism for the laws of physics to vary in each new universe as it arises.” https://www.ft.com/content/9a306276-bf03-11e3-8683-00144feabdc0
