But is physical reality truly random? :>
- lawrenceyan 7y agoQuantum theory pretty conclusively shows that it is in fact.
- FakeComments 7y agoIt does not — that’s merely a philosophical interpretation, and one which relies on an extra assumption. Quantum mechanics says that it’s not Euclidean-locally predictable, but we’ve learned that quantum mechanics isn’t Euclidean in the first place — so there’s no experimental support for the assumption of non-determinism. People didn’t know that originally, and so when faced with non-Euclidean or non-deterministic, they chose to assume non-determinism. (That assumption is the Copenhagen interpretation.) However, later evidence showed that non-locality was necessary, and the assumption of non-determinism became an extra (and unrequired) assumption.
- 481092 7y agoDoes it? Maybe on the micro but at the classical macro level, it's pretty deterministic. Why not both? And in some beautiful Taoist fashion, perhaps they're mutually complementary, both opposites need to exist for reality to exist as is. But as a layman, I know enough to know how hotly debated this subject is so I digress.
- voxl 7y agoConclusive is a stretch. I personally think that reality has "true-randomness" or, is otherwise not deterministic. Unfortunately, at least from a philosophical perspective for now, things like Superdeterminism have to be considered. One might come to the conclusion that there are both deterministic models, and randomness models of our universe, and thus the physical laws don't commit one way or the other.
