Time is a very important concept in physics.\n\nActually, even in physics (or very _much_ in physics), time doesn't \nfollow the nice procession that Matthew is kind of asking for.\n\nIn physics, particles can go backwards in time or forwards in time (the \n_likelihood_ that a photon moves at exactly the speed of light is higher, \nbut on a quantum scale, strange things happen). \n\nAnd everybody should by now know what relativity says: time does not \nimpose an \"ordering\" of events outside of the so-called \"cone of light\". \nThere is only an ordering imposed by _causality_, not by time.\n\nThat, btw, is very similar to git. The only _true_ ordering in git is \ncausality. Time itself tends to have certain properties that makes it \n_look_ like it is about causality, but in real life there is just a strong \ncorrelation.\n\nNature is sometimes stranger than our everyday experiences would have us \nbelieve. And \"time\" is a hell of a lot more complicated than just a global \none-dimensional entity, steadily ticking away.\n\n\t\t\tLinus\n"}]}
