Liongold is very incorrect. General Relativity (which is not even Einsteins, he plagiarised Henri Poincare's paper) is false because it does not admit that everything, including motion is absolute. Quantum mechanics is nothing but a mathematical mess. It decribes nothing about HOW matter acts and reacts with other matter. The mathematics itself is also highly wrong, "renormalisation" is the most laughable aspect of QM, as they think they can just ignore things in order to get the results that fit together with other theories and equations. It has no relation to reality.
