What is the transmission mechanism? Science knows of gravity, electromagnetism, the strong & the weak nuclear forces. Is there some 5th mechanism? If so, it seems strange that it is only detectible by the human brain. What is the range of telepathic communication? Does it fall off linearly with distance? Is there an inverse square law degradation in the strength? Most of the articles I have read seem to imply that signal strength does not decrease as distance from the source increases. When doctors or other investigators monitor brain activity, they attach detectors directly to the skull. As far as I know, brain activity is not detectable by scientific instruments at distances beyond inches or perhaps a few feet. Believers in telepathy do not report much (if any) degradation in signal strength when plotted versus distance. When human abilities and/or characteristics are measured, a bell-shaped curve is usually the result. For some abilities, the plot is not symmetric, but is similar to a bell shape. In all that I have read about telepathy (& other paranormal abilities), it is claimed that some folks have the ability & many do not. Not at all like the bell-shaped plot relating to other abilities. This seems very strange to me.
