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.

Discussions

• The answer to this is a bit complicated. If you look at a quantum physics textbook that mentions collapse, such as "Introduction to quantum mechanics" 3rd edition by Griffiths and Schroeter, you will [stackexchange, 5 points]
