Abstract
First, we demonstrate Bell’s theorem, without using inequalities, for an experiment with two particles. Then we show that, if we assume realism and we assume that the ‘‘elements of reality’’ corresponding to Lorentz-invariant observables are themselves Lorentz invariant, we can derive a contradiction with quantum mechanics.Keywords
