I can't believe the claim, since telepathy has never been demonstrated- however! I think I have to admit that there isn't any law of physics that says telepathy is impossible, theoretically. It would certainly be possible over short distances if humans had specialized organs for transmitting and receiving electrical signals, like an electric eel does. Since we don't have that organ, the signals a human brain can produce are very weak, which is why they put electrodes right on your scalp and not a few inches away. If telepathy could occur, it would have to be in a very electrically quiet place like the Amazon. It could be that telepathy is real but just never tested in an electrically quiet enough environment. The modern world is shockingly noisy- cell phones, radio towers, the power grid, and wifi hubs all produce constant electrical noise. Even in the Amazon I'd say the probability that this is real is very very low, but hey, who knows.
