Surprisingly a 100 lb man ( EDWARD LEEDSKALNIN Builder of Coral Castle near Homestead, Fla.) single handedly moved 30 ton stones and constructed a megalith park in recent times. It is a modern wonder and can be viewed here: http://www.mysteriousworld.com/Journal/2003/Winter/Artifacts/ or secondly https://www.coralcastle.com/ It is pretty famous and has been documented on TV's "In Search or', "That's lncredible" and "P.M. Magazine." Publications ranging from Reader's Digest to the National Enquirer have sent reporters to the castle and numerous scientists and engineers have tried to seek the answer to this seemingly impossible feat. Whenever Edward Leedskalnin was asked, “How did you build the Castle?” he replied, “It’s not difficult really. The secret is in knowing how.” Edward Leedskalnin would go so far as stating that he could see beads of light on objects that he said were the physical presence of nature’s magnetism. He explained that scientists have incorrect knowledge of atomic structure and electricity. He stated that all forms of existence are made up of three components, North and South poles and neutral particles of matter. He claimed to have “re-discovered the laws of weight, measurement, and leverage.” Edward Leedskalnin stated that these laws “involved the relationship of the Earth to celestial alignments.” Beyond these sketchy explanations, Edward didn’t say much. Ed's brochures about his Castle proudly stated, “I have discovered the secrets of the pyramids, and have found out how the Egyptians and the ancient builders in Peru, Yucatan and Asia, with only primitive tools, raised and set in place blocks of stone weighing many tons!” He died without revealing his secret, and the only apparent clue he left was a plaque found over his bed which read, “THE SECRET TO THE UNIVERSE IS 7129 / 6105195.” his wikipedia feature on him and "corral castle" where he manipulated over 1100 tons of stone can be found here. http://en.wikipedia.org/wiki/Edward_Leedskalnin Nosy Neighbors and the U.S. government tried to discover his secrets but he was pretty closed mouthed about it. I was surprised to see that he published a book on "Magnecity" (online book link below), as his theory was that magnets smaller than light particles comprise the universe, and that that is what elecricity "is" hence "magnicity". We know how to make and use electricity but its underlying composition has always been somewhat of a mystery. The paper is filled with amazing experiments, and a patent for a power generating device he invented. I think it is a must read for anyone interested in physics. This man seems to have discovered how to counteract gravity in stones through the use of the "gravity particles" he claims is the "ether". He did most of this construction at night to keep his methods secret, as the government, reporters, and keen neighbors wanted to know his secrets. One fact they do know, and that is heavy machinery was not used. His book is free online here: (fantastic read) http://www.keelynet.com/unclass/magcurnt.txt It is amazing how the internet can allow us to see for ourselves texts that might otherwise go unnoticed, or hard to discover. What I found most convincing of his theories was that he used them in a proven way. Including balancing a nine-ton stone gate so perfectly that even a child could push it open. In 1986 the gate stopped working. They needed a 50 ton crane and 6 men to fix the gate. A task he did by himself. Hope it opens a few eyes. There is no denying what this man accomplished. If you are not convinced by my links. Google Search: "EDWARD LEEDSKALNIN" or "Corral Castle" A rough idea on what people suspect was his "anti-gravity" method is that all atoms are comprised of magnets. The polarity is what keeps us grounded. I am not a great physicist and would like to hear "possibilities" from some of you here. It certainly is not Newton, but .... (see for yourself) I am hoping someone here grasps what he did based on his book (link above), and invent some sort of levitating car or something like what the egyptians had. lol. (no seriously) look at this ancient egyptian heiroglyphic. http://www.enterprisemission.com/images/abydscmp.jpg. Hmmmm. lol maybe the wheel was not such a great invention after all?
