Bruno was working with metaphysics... not a guess. Same science that Aristotle, Ptolemy, Copernicus and others used before the tools for actual experimentation were available.
I also really liked the presentation of the multiverse theory even if it is also in the realm of metaphysics. It seems more reasonable that rationalizing out how original sin broke the universe for all living and non-living thingsthrough-out creation... :confused:
Metaphysics, as a philosophical study, still has validity. But Aristotelian metaphysics is a lot different than the Ptolemaic system which was based on observation of the sky. The calculations got too complex when based on geocentrism.
It seems to me that nothing in classical metaphysics could have led Bruno to a conclusion about the structure of the solar system or the universe. And original sin is theology, not philosophy or science; it has nothing to do with cosmology.
I have nothing in particular against the multiverse theory, but it seems at present to be not much more than Bruno's guess about the stars.
I suppose I shouldn't be so negative about popular science shows, but I would have gotten more out of a one hour lecture by a cosmologist!
