But, what interests me most is:
D'Espagnat's contribution is most easily explained with reference to a series of famous experiments conducted in France and Switzerland in 1981-82 on the polarization of photons. A photon is a massless elementary particle with no electric charge. "Polarization" refers to the oscillation of the waves of the photon.
A team of physicists under the French physicist Alain Aspect found that a change in polarization of a photon miles from a separate photon could be detected in both – and it would all happen faster than the speed of light. This violated a series of principles on the behavior of particles.
For instance, it challenged a basic premise of classical physics: Nothing can travel faster than the speed of light. That, at least, would be true if "travel" is the operative word.
Einstein was talking about this right before he died. It was part of his ideas about simultaneity. He was talking about the fact that his work was leading more toward explaining telepathy than "travel". I've nursed a wound almost all my life that Einstein died before he got to discuss this thoroughly with me.
