Although antigravity devices remain in the realm of fantasy, scientists in Israel have managed something equally impressive. Utilizing a phenomenon called quantum trap not only managed to make objects remain stable in air but also to ” fly ” in any direction!
Natural phenomenon can be observed in any subject. Nor under any circumstances. The drive used in the video is made of special ceramic material has been cooled to -185 degrees Celsius. Thus becomes a superconductor (or nearly perfect conductors of electricity) and when placed over the magnetic surface of the magnetic field lines to cross and make it hover in the air!
As for flying saucers and spaceships? So you have to do a little more patience!
