The caveat that first comes to mind is that the only way to make an instantaneous change in the shape of the field is to make an instantaneous change in the matter distribution, and the speed of light definitely limits your ability to move around that fast. On sheer intuition, I suspect that if one did the math, it might turn out that in order to make, within less than 1 second, a change in matter distribution large enough to be detectable more than a light-second away in the geometry of that matter's gravitational field, it would require a very large amount of energy. (Shift the earth at the speed of light for a few tenths of a second, and observe exactly when the moon's orbit changes?) -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
