Conversations Beyond Science and Religion – Is the Multiverse the Final Answer?
An unavoidable fact of science is that the universe is finely-tuned to allow life to exist. Fundamental forces and constants, from the rest mass of the electron to the sun’s distance from the Earth and the strength of “dark energy,” appear to be adjusted to ensure a stable universe and the possibility of life. Scientists, faced with this fine-tuning, confront the age-old dilemma of whether to bring a supreme being into the picture or to seek a “natural” explanation. But science’s natural explanation for the fine-tuning problem is a humdinger: an increasingly number of physicists are jumping on the multiverse bandwagon, supporting the idea that our universe is just one of a near infinite series of other universes, forming a vast landscape of other worlds. On this show, guest Bernard Carr, Professor of Mathematics and Astronomy at Queen Mary, University of London, and editor of the book, Universe or Multiverse, joins host Philip Mereton in a conversation on the development of the multiverse and whether this amazing idea is science’s final answer to why the cosmos appears so finely-tuned.
