One of the interesting ideas expressed in "The Principle" is that the multiverse is seen (by one its leading proponents) as the extension of the Copernican Principle to its logical conclusion.
Discovery Institute's Denyse O'Leary follows the multiverse to its logical conclusion.
"Logic and reason are likewise irrelevant. Consider the multiverse claim that there are "infinite copies of you and your loved ones leading lives, up until this moment, that are absolutely identical to yours." Mathematician George F. R. Ellis notes that, if so, the deep mysteries of nature are too absurd to be explicable and that the proposed nine types of multiverse in one scheme are "mutually exclusive." True, but in a multiverse, "inexplicable" is okay. "Absurd" and "mutually exclusive" are meaningless concepts. It is equally meaningless to assert that one event is more probable than another. As David Berlinski puts it, "Why is Newton's universal law of gravitation true? No need to ask. In another universe, it is not"(Devil's Delusion, p. 124).
You can, of course, make reason and logic your personal brand of nonsense if you wish. In that case, statements like this will annoy you: Earth's habitability rating has "taken a hit" because it is too close to "the warm edge" of our zone. Earth's habitability has a probability of 1, so how can its rating take a hit? Berlinski would likely say, no need to ask. In another universe it has not."
"A question arises: If, in the multiverse (especially the many worlds version) everything possible is true, why do cosmologists trash traditional Judeo-Christian beliefs? Because there is a critical catch: Anything may be true, including contradictory states, except serious dissent from the Copernican principle--the principle that Earth and our universe are nothing special. Physicist Rob Sheldon sums it up:
'Multiverse theory is designed for one purpose, and one purpose only, and that is to defend atheism. It makes no predictions, it gives no insight, it provides no control, it produces no technology, it advances no mathematics, it is a science in name only, because it is really metaphysics.'"
It is time for a serious examination of this Copernican Principle; what is it, how did we accept it, what are its ultimate consequences for our science, our faith, our culture, our future?
"The Principle" is coming.
The timing couldn't have been better.
