Suppose one said instead "any conceivable interaction"? (This is 
thorny territory, but I suppose superstrings and brane bulks etc are 
not observable, but we account for what *is* observable by specifying 
certain interactions that calculation draws out as likely, or, better 
yet, impossible, from those postulated primitives.)
