Relativity and quantum mechanics
Even with the defining postulates of both Einstein's theory of general relativity
pl-2301 and quantum theory being indisputably supported by rigorous and repeated empirical evidence and while they do not directly contradict each other theoretically (at least with regard to primary
pl2303x claims), they are resistant to being incorporated within one cohesive model. Einstein himself is well known for rejecting some of the claims of quantum mechanics. While clearly contributing to the field, he did not accept the more
pl-2303x philosophical consequences and interpretations of quantum mechanics, such as the lack of deterministic causality and the assertion that a single subatomic particle can occupy numerous areas of space at one time. He also was the first to notice some
ps222 of the apparently exotic consequences of entanglement and used them to formulate the Einstein-Podolsky-Rosen paradox, in the hope of showing that quantum mechanics had unacceptable implications. This was 1935, but in 1964 it was shown by John Bell (see Bell inequality) that, although Einstein
ps223 was correct in identifying seemingly paradoxical implications of quantum mechanical non locality, these implications could be experimentally tested. Alai Aspect's initial experiments in 1982, and many subsequent experiments since, have verified quantum entanglement.
