:I've heard, rarely but occasionally, the phrase "action at a distance" to refer to one particle acting on another particle that's outside its light cone. Have either of you heard that one? Maybe we should include that interpretation of the phrase as well? --[[User:KSorenson|KSorenson]] 17:56, 14 November 2009 (EST)
