.....The apparent paradoxes of quantum mechanics in fact disappear once we realize that elemental processes do not distinguish between past and future or cause and effect. Experiments that seem to require superluminal connections when viewed in our familiar time direction are perfectly subluminal when the arrow of time is reversed.
.....While this violates our common intuitions, those intuitions are based on our experiences in a world of many particles where phenomena that are fundamentally statistic nevertheless behave very predictably. The arrows of time and causality are not elementary. Rather, they are heuristic principles we have invented to conveniently describe the macroscopic world of our experiences In our lives, time flows one way, for all practical purposes. While it is technically possible for the atoms in your body to assume a more youthful configuration, the chances are far greater that you will age with the rest of us. By consensus, we define the arrow of time to be the direction in which we all are observed to age. At the quantum scale, however, no such consensus can be formed as particles interact without regard for an arrow of time.
