>>12462937The belief that "everything up to relativity is fine" is the source of all confusion in physics, it entraps the mind in a box from which it cannot escape.
It's not that quantum particles break relativity, it's relativity that is incompatible with reality, and experimental evidence of the fact is worked around to keep relativity from collapsing.
Things that arise from the interaction between quantum mechanics and special relativity (QFT) are:
>fundamental non determinism OR fundamental non realism>the zoo of antiparticles, and with it nonsense questions about the asymmetry between matter and antimatter>quantum spin as a fundamental property of particles rather than a property depending on the unknown initial conditions of a particleIt IS relativity that is the problem, and with it QFT.
