many worlds hypotheses

If a grand multiverse contains everything that’s possible, it ends up explaining nothing. On this ID The Future, physicist Brian Miller concludes his conversation with mathematician Elie Feder and physicist Aaron Zimmer, hosts of the Physics to God podcast, about their unique formulation of the fine-tuning argument and their rigorous examination of the multiverse hypothesis. In Part 2, Feder and Zimmer explain in detail three premises they use to critically evaluate the strength of multiverse theories. They contend that if a multiverse model posits infinite universes, each with their own different laws of nature, it’s a naive multiverse that hasn’t solved the fine-tuning problem. To properly evaluate multiverse proposals, a third premise is needed: one that can explain the typicality Read More ›

Today’s ID the Future continues (by permission) the long-form conversation between Stephen Meyer, author of the newly released USA Today bestseller Return of the God Hypothesis, and UC-San Diego physicist Brian Keating. Here in part two the conversation turns to quantum cosmology, multiverse hypotheses, Stephen Hawking, and Hawking’s now-you-see-it/now-you-don’t use of imaginary time to deny a cosmic beginning. Meyer argues that Hawking’s imaginary-time trick doesn’t wash, there remains powerful evidence for a cosmic beginning, and that this beginning is best explained as the creation act of an intelligent, immaterial being. Also, Keating and Meyer tackle the question: Did Isaac Newton really blunder by invoking a God of the gaps to periodically tweak the solar system to smooth out perturbations? That is, was Newton led Read More ›
