I'm getting more and more confused. My (layman's) understanding was that the Aspect experiment had eliminated the possibility of the "hidden variable" theories which maintained that quantum events could be causally determined in a more than statistical way. Physics gurus, help: is it, or is it not, now *known* that the universe is not deterministic, at least at the subatomic level? - From the Crow's Nest - Kenn Barry NASA-Ames Research Center Moffett Field, CA ------------------------------------------------------------------------------- USENET: {ihnp4,vortex,dual,hao,menlo70,hplabs}!ames!barry SOURCE: ST7891
