Time is another dimension in addition to the three we see visually, time is felt as opposed to seen. Like the three dimensions (width, depth and height or x,y,z) we can "measure" time. There is strong theories that other dimensions exist - even space-time is technically a diminsion we cannot properly measure but we can percieve it at work at a quantum level. Do any of you remeber the Simpson episode where Homer found himself in 3D world? That shows how our perceptions are framed by the dminesions we are in. Time is not a constant - Einstein's General Theory of Relativity was proven with synched atomic clocks that were split up - some on earth some orbiting - they were efound to be out of synch. in fact, communications sattleites have to "phase" their internal clocks in order to compensate for the spped of thri orbits.
Time was never created, it is a construct of our own conciousness and it is as fluid as a river, some fast spots, some slow and the occasional point where an eddy reverses the flow. As a believer in God, I see how multiple dimensions can exist and if you are no bound by 3D and 4D (time) then time is irrelevant and both the past, present and future merge. Interestingly, the Heisenberg Uncertainty Principle states that you cannot measure the position and momentum (velocity - a function of time) of a particle at the same "time". If you could you would be able to predict the future with stunning accuracy. The laws of big things simnply break down and are no longer applicable at the level of particles. Therefor it is plausible that the laws that seemingly bind time at the level of big things will breakdown at the level of small things. Timis is, pardon the plagarism - relative.
