"Time's arrow, or what universal property is asymmetric, anyway?" A lot has been made of time's arrow not appearing in the equations of Newton, statistical mechanics, relativity and quantum mechanics - none preferring that past precedes the future or vice versa. Some very specific particle processes do seem to follow an asymmetry of time, but they are the far greater exception for interactions in general. We ask if time as a universal property has a preferred direction. I ask if any cosmological phenomenon has been shown to obey an overall physical vector.
