The challenge for “hidden variables” theories is to establish a theory whose results are consistent with those of quantum theory. Returning to the principles of “hidden variables” theories at the end of the second chapter, each photon has a number of qualities that determine its behavior in each experiment or measurement.
In 1964, John Stewart Bell, a physicist specializing in the study of elementary particles at CERN near Geneva, concluded that any theory that wanted to preserve the principle of locality and the principle of determinism must differ in its results from the quantum theory in the photon pairs experiment. This theoretical conclusion was so important that it became the main engine of most theoretical and practical research in this field in the last 40 years.
