The other reason this particular topic is of such pressing interest to me is that more and more, everywhere I look I am seeing references to EM. Gravity, is being linked to EM, as is communication between cells, as is mental sensitivity in animals, as ar cellular anomalies in humans. Even nuclear reactions, supposedly a separate force all together produce powerful EM fields, and radiation is a property of very high frequency EM waves. I am curious if EM will turn out to be, ultimately, the unifying principle of physics.
