> Quantum Mechanics has been aggressively and extensively tested against measured observations of reality and has not yet found a discrepancy with it That isn't true. Here's a discrepancy: the universe appears to be following the laws of general relativity, but quantum mechanics does not account for this and returns wrong answers. Here's another discrepancy: quantum field theory predicts an energy density of the vacuum off by 120 orders of magnitude of the observed value. "All models are wrong, but some are useful." But it's disingenuous to claim we haven't even found any discrepancies and that it appears to be a perfect model.
