On the ontological ambiguity of Physics facing Reality

We discuss in this work the contradictory position in modern Physics between the existence of a microphysical quantum Reality and macrophysical classical one. After discussing some basic concepts in Philosophy, we revisit the situation of Quantum Mechanics results, particularly after the confirmation of violations of Bell’s Theorem, and its significance to create a tension between the micro and the macro world, which is very fundamental and unsolved.
