One of the fundamental puzzles of our Universe is that we have a definite 'arrow of time' a distinction between the past and future. This puzzle can be explained in this theory because an important aspect of Heisenberg's Uncertainty Principle ∆×∆p×≥h/4π is that it does not work in the same sense forward and backward in time. It is within the rules of quantum mechanics to calculate backwards and find out what the position and momentum was at some time in the past. This precisely fits in with our everyday experience of the nature of time, moving from a known past into an uncertain future. Add to this that Heisenberg's Uncertainty Principle can be reformulated to say that it is impossible to simultaneously measure the energy of a particle and the interval of time ∆E ∆t ≥ h/2π for which it has been in existence. When we consider what happens in a region of empty space in a very tiny interval of time, there will be a large uncertainty in the energy content of that region. It has been said that energy appears out of nothing, but the most simple and most beautiful explanation for this is that we have a process of continuous creation or change. A process of change that at the smallest level can be seen as the Planck Constant ħ=h/2π as a constant of action within the uncertainty of the flow of Time itself forming the dynamic geometry of spacetime. This might sound insane, but this theory is based on just two simple postulates 1. The first is that the quantum wave particle function explained by Schrödinger's wave equation does not just predict what the wave-function will be in the future, but this process represents the forward passage of time ∆E ∆t ≥ h/2π or Arrow of Time itself photon by photon or moment by moment. 2. The second is that Heisenberg's Uncertainty Principle ∆×∆p×≥h/4π that is formed by the wave function is the same uncertainty we have with any future event This process of continuous creation or change we see and feel as the flow of time itself. Forming an infinity of possibilities at every point in space and every moment in time that we can interact with turning the possible into the actual!
