[QUOTE="spiney, post: 167008, member: 192438"] Sorry, Channel Hopper, I know I'm a truly irritating pedant, but ...... Gravity is a "conservative field", in which any object's potential is a function of position. Cavorite is impossible, because to move in a gravitational field means changing the potential, so there can't be a "gravity shield" ..... If this were not true, then "perpetual motion" would be possible (it isn't). Also, nothing could exist, because any objects in the universe would spontaneously explode ...... (The mentioned links accept this, they're not suggesting otherwise!). (added) See: [URL="http://en.wikipedia.org/wiki/Talk:Anti-gravity"]http://en.wikipedia.org/wiki/Talk:Anti-gravity[/URL] ; also: [URL="http://www.kilty.com/pmredux.htm"]http://www.kilty.com/pmredux.htm[/URL] And much other stuff, just use Google ..... All applications for "perpetual motion" machine patents now have to be accompanied by a "working model" (!). Regarding general relativity, the field equations are non linear, hence only solvable in special cases, and there's always going to be "interesting" solutions ...... [/QUOTE]
