Oh, I am fascinated by this. I used to think we were not alone. Then I began to understand the distances involved.
It amazes me that we can pick up so much information through light and radio waves.
Still more amazing all we know about the entire electromagnetic spectrum come from 4 equations. Without them Einstein would have remained at the patent office and Nikola Tessa would have never invented alternating current.
But who wrote those 4 equations? No one really. The were converted from field equations to vector equations by a self-taught mama's boy named Heavyside, who took the original 200 field equations written by the 19th Century mathematician James Clerk Maxwell and threw all but those four out.
What's in the other 196? No one really knows because the original work is obscure and only a handful of copies remain. But they may actually describe how to get free energy, how to transmit it wirelessly over vast distances (Tesla's project), how to move from point A to point B anywhere in the universe, among many other seemingly impossible things.
