<HTML>Do you really mean *gravity* negating? After all, there might just be no such thing as gravity for some other thing or process to negate it. That there is acceleration attributed to gravity does not mean that such a theoretical property as gravity should have acceleration attributed to it.
For example, when a bar magnet is dropped into a superconductive dish it floats and appears as though it is repelled by its exact mirror image below the dish. Though I would not consider this a gravity negating event, as it is not clear that the theoretical property, gravity, is being negated. Although, it is clear that acceleration is being negated. Now, at that kind of temperature one would have, in effect, a static model. One can imagine, however, that a dynamic model might work at a much higher temperature if the structural set up of the negation process is such that it can extend its influence within a localised dynamic system. Now, considering acceleration itself as the phenomenological condition for the theoretical property of gravity, then it follows that any process or thing that could reduce that acceleration would give rise to a phenomenon that might seem as though it were gravity negating or reducing. However, the effect, phenomenologically speaking, would rather be a localised resultant deceleration. This would be analagous to a localised drop in pressure in a closed, localised and dynamic system. Now, consider an analogy with wind. Wind is the result of a localised low pressure in a delocalised dynamic pressure system. Low pressure sucks air toward it and what we call wind 'blowing' is created. Now, compare this with deceleration. It produces localised low pressure and thus reduces acceleration. Such a reduction is a localised negation of a delocalised acceleration field. The effect would be such that there would be an appearance of the negation of the theoretical property of gravity, with the result that bodies within that localised system would have lower weight. Their mass would not change as such but mass is not a phenomenological property, whereas weight is. It is inconsequential as to whether the deceleration effect is the result of force input (conventional) or whether it is preventing force input (unconventional), although the unconventional is more interesting of the two. The localised resultant force would be lower than the overall delocalised field. The question is, what could create such an effect at high temperatures. Well, scrambling or re-orienting the field in which acceleration is basically a uniform occurence might just do the trick. Now, if magnetism, in a static model, can have a spontaneous re-oriented mirror image with a resultant floating effect, then in a dynamic model such as spinning the magnet it might draw the field lines toward it in a tapered helix. Depending on where the process is initiated and on the initial ascription of orientation, this could be a tapered helix from top to bottom or bottom to top. The resultant effect would be the drawing of field lines along the tapered helix and a roving localised low pressure with the convection current through the central point. Probably more mad nonsense but an interesting experiment to try from a theoretical perspective.</HTML>
