Thanks for your knowledgeable response Physics Guy.Physics Guy wrote: ↑Sat Jul 18, 2020 2:44 pmPhysics has always been perfectly compatible with theism. The distinction between an actively intervening God, and a Deist God who sets everything in motion and then just stands back to watch it all unfold under strict causality, is moot. Strict causality means that everything that ever happens is implicit in the initial conditions, and so whoever sets the initial conditions determines everything that ever happens afterwards.
Quantum mechanics does not represent a change from some bad, old, overly rigid concept of determinism to some loose, vague, spiritual New Age view. Quantum mechanics is in a major sense much stricter and stronger in its determinism than classical mechanics. It's extremely rigid and mechanical, not vague and fuzzy at all, and it allows no special role for mind or spirit. The special status of observation in quantum mechanics is for machines like Geiger counters and photomultipliers, not consciousness, and anyway quantum measurement theory is a cludgy jury-rigged part of the theory that is still in place after a hundred-odd years just because physics is hard.
Quantum mechanics is strange, but not mystically Oooh-aahh Gee-whiz strange. It's bizarrely and nonsensically strange, like an alien children's game. It's compatible with theism, too, but less comfortably so than classical mechanics is. The God who made a world that runs on quantum mechanics must be quite a different kind of being from us. So it makes no sense for theist apologists to appeal to quantum mechanics in particular, as if it tips the playing field in their favor. We and everything we think of as real might still be ideas in the mind of God, but if so quantum mechanics implies that God's is an alien mind.
Saying that everything boils down to information isn't really an idea because it's a tautology. Many different states of the universe are in principle possible as far as we know. The actual state of the universe is one of them in particular. Specifying one possibility out of many is what is called "information" in communication theory. So Yay, we can now use a new word for what we've known all along. That's all it is. Wheeler was a good theoretical physicist but an even better marketer, so some of his banal observations got attention. None have really gone anywhere so far.
