Antigravity Technology and Military’s anti-gravity research programmes including Disclosure Project
In Newton’s law of universal gravitation, gravity was an external force transmitted by unknown means. In the 20th century, Newton’s model was replaced by general relativity where gravity is not a force but the result of the geometry of spacetime. Under general relativity, gravity is the result of following spatial geometry …
