    This is just a hypothesis, but I'm thinking we could define entropy as the degree to which cause is connected to effect. In a system with very high entropy, nearly all events are perfectly random, un-directed quantum effects. Particles and photons are bouncing around willy-nilly in a way where it is almost impossible to determine the cause of any given particle
    moving to any given destination and trace it back more than just a few moments in history.

    Now imagine what an ordinary chain of events would look like if you saw it happening backwards in time. The lights come on in Jimbob's home, then he flips a switch on the wall. Jimbob wakes up in the morning, then his alarm goes off. The engine in his car stops, and then he turns the key. It all looks like random nonsense. Nothing is causing anything.

    Maybe the reason we perceive an arrow of time is because all of the ordered events in our area of the universe are polarized to each other somehow. It's either because all the other events happening around us don't have any order to them in the first place, or maybe it's just that we don't see any order in them unless they are flowing in the same temporal direction as we are.


    extension:

    We should be able to view parts of the future by analyzing the random as though it were an event happening backwards in history. (or looking for such events in random mixtures...) Also, if we detected an event happening backwards in history, and then interacted with it (we would appear random to its perspective, but not our own.) perhaps we could actually send information backwards, or an event backwards, or .....etc..... We could encode an idea, and maybe even tell that idea to encode one back for us to detect again in our realm of reality.

    Possibly, low entropy means the degree to which an event is isolated from backflows. So, a low entropy back flow event would also have to be very isolated from forward flows in order to be low entropy....

    This last part is the barrier to time travel paradoxes. If a backwards traveling event were motivated by a forward traveling event, then it is not isolated from that forward traveling event, and therefore could not have a low entropy, and would therefore not carry any useful information.

    Or better yet: the information that is possible for it to carry is limited to those things which do not interact with forward flowing events that cross its path.

    OH; you mean like gases in the atmosphere , right ?

    One of the time traveling problems often overlooked : you took a deep breath now

    but exhaled on a previous "time-tract" when the atmosphere had less background

    radiation as well as polution and the reslut caused irrepairable damage that

    PREVENTED YOUR BIRTH !
