I am linking the idea that some of these extra dimensions in the string theory might be large enough to be measured in the lab, large enough to be bigger than groups of neurons in the brain, and the idea that there can be only one photon. There can be only one. Highlander.
I seem to remember reading somewhere that if ESP were real, then its explanation would lie in the realm of physics instead of psychology.
I think it was an idea attributed to Einstein in one of those popular books that mesh mysticism with quantum mechanics.
Whatever its source, I am unsure of its veracity.
