"OK. it basically comes down to this : true anti-gravity (at least on a macroatomic scale) is an impossibility according to all the known laws of physics (If I'm wrong, please tell me, because I'd like to see those equations). However, many things can be made to appear as if they are antigravitic. For example, take the little-understood phenomenon of the Bifield-Brown effect, discovered by T. Townsend Brown. It basically states that a properly chaped capacitor, when charged to a high enough voltage (at least 10 KV, often more) will thrust towards the positive side through some electrokinetic field effect unrelated to the ionic wind (I have tested this myself and it works). This is often called "electrogravity," but that is completely wrong. It is electorkinetic propulsion. The thrust is the same up and down as it is side to side if you rotate the capacitor. It is completely unrelated to gravity. Another example it magnetic repulsion. Has all the "symptoms" of true antigravity, but it's not - it's just magnetism. In conclusion, antigravity-like effects can be produced in many ways, but true antigravity (without the assistance of a black hole or some similar device to warp the fabric of space itself) is an impossibility."
