Do we fully understand why and how quantum entanglement happens? Better yet, will we ever understand it? Can it be reduced to a mechanics or is it like the rest of quantum mechanics, which is, by scientific definition, indeterminate? As a layman to physics, I don’t quite understand entanglement and it seems like some form of magic (minus the rabbits-in-hats part).
Physics Phriend, even physicists don’t fully understand quantum mechanics or entanglement; they just use and accept the theory. It’s a probabilistic theory, so therefore indeterminate. Quantum entanglement appears magical, but it’s happening on extremely small scales. So then, apparently, magical things can happen if they are within the uncertainty limits. It’s not magic to us, because we do not directly experience it (unless you wish to call everything magic and a miracle, which it essentially is).
