The author proposes two ways to test a strange but consistent alternative to standard quantum physics that could refute the “spooky action at a distance” explanation of the standard theory. Causal quantum theory assumes that measurements are well-defined physical processes, are localized in space–time, and never give perfectly reliable outcomes, among other conditions. It also predicts outcomes counter intuitive to anyone familiar with standard quantum theory.
