Hi, I'm new here but have been working in the physics field for years. Most assume time to be infinite. But there appears to be a natural limit on the expansion of time. In the beginning, there was nothing and no possibility of change. How long this state lasted is a misleading question for without the possibility of change there can be no time, since time implies both 'before' and 'after'. Since there was no possibility of change, nothing can, or did happen. Finally the possibility of change occured. This allowed time to begin. The only alternate to 'nothing' is 'something' and so all of the 'energy of activation' appeared at a single point in the first moment of time, t0. While time began, space had not. All of the 'energy of activation' was in one spot. At the next moment in time t1, that energy began to rotate. This led to the three spatial dimensions, x, y, and z. But the spatial dimensions lagged the time dimension. So while the index of time was 1 (t1) the indices of x, y, and z is 0! This is why time, of all the dimensions, has a direction. We can move freely in both directions in any of the x, y, and z axes but can only move forward in time. This is because time was the predicate dimension and leads with x, y, and z following in it's wake. Max Planck derived the 'Planck minima' for the least amount of energy required to create a quantuum state. h = 6.626 x 10-34 J x s While this is an incredibly small amount of energy, it is most definately not zero. By the same token, the 'energy of activation' (ea —the total energy in the universe) is quite large, it is also most definately not infinite. Since each quantum state created requires a 'Planck Minima' of energy and that value is small but not zero, then if we divide the total amount of energy in the universe, ea, which is large but not infinite, then the result: ea / h will be a very large, but not infinite number. This number represents the maximum possible number of quantuum states that can be created. When no more states can be created (since there is no more energy left) time itself, must stop. Thus we can see that quantuum physics itself limits the amount of time in the universe and that time is not 'infinte' as most presume, but has a natural limit. This limit of time, shows us the end state of the universe — a state where all quantuum states are equivalent, each with a 'Planck Minima' of energy, h. One interesting aspect of this view is that both the moment of creation (all energy in a single point) and the moment of entinguishment (all energy spread uniformly with one h's worth per quantuum state) are both states of 'Grand Symmetery'. That is to say that the universe as a whole is symmetrical. In the first case by having all the energy in a single point of no dimensionality and the second by having the energy spread absolutely uniformly. Once the universe has acheived this 'Grand Symmetery', it is free to 'wrap around' from one state of 'Grand Symmetery' to the other and thus the universe again explodes in yet another 'big bang' creating the next universe from the ashes of the prior. Do you think there is any merit to this view or have I been smoking the expensive imported blend for too many years?
