I had suspected that since gravity works equally on both types of particles there might be "some" interaction. But on reflection, I know that gravity is multi-billions of times weaker than electromagnetism so one would have to find a way to force mirror anti-matter to interact with normal matter, if it could indeed be done at all. xponent Always With The Questions Maru rob _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
