This video highlight "History of Anti gravity, why this technology always been kept under top secrecy.
Every thing on the earth has weight due to gravity. The Pyramids of Egypt, has always surprised the researchers by its mysterious structure, each stone used in the Pyramid, weighing about 2500 Kgs. Not only this they were brought from other side of desert, it seems impossible with the technology of ancient Egypt. Some scientist believe that they had Anti gravity technology by using this technology they could built such a Wander of the world.
In 1923, the founder of Coral Castle of Florida, Edward Leedskalnin, claimed that he has known the secrets of Anti gravity technology used by the early Egyptians, and with the help of this technology he has built the "Coral Castle" without using modern technology only with the help of simple Tripod, which seems impossible. He did not tell this secret to any one till his death in 1951.
Some researchers believed that his secret might be hidden in the black box which could be seen on top of the tripod, in some pictures.
Nikola tesla, also worked on this technology, but he didnot disclose its finding, and interestingly, his research papers were stolen after his death, which might had the findings of the technology.
Till 1990s, no any plausible research in development could be seen in this technology, till 1997 when Dr. Ning li, published her research papers for her experiments and findings, on anti gravity. In 2003, she established her own company "AC Gravity LLC". The US state Department funded her Company with a grant of 45000 US dollars. Till then there is no any know-how about her
Every invention has its own benefits and disadvantages, but for Anti Gravity technology there are the great chances that this could be weaponized. This might be the reason "Why this technology always been kept under top secrecy?"
