In the realm of quantum mechanics, movement is not restricted to occuring in the future. Nifty, right? Well, Boltzmann’s explanation of the 2nd Law of Thermodynamics describes entropy not as an absolute, but rather a consequence of probability. Relative to the form of energy exchange, entropy takes the “directionality” of its total components, given by its probability state. In the case of time, the quantum components greater probability state is said to be going forward. By increasing the scope of energy to what we regard as macrocosmic space-time and all the quanta that compose it, we can see how the probability state given by quantum entropy emerges as a one-dimensional arrow.
