Time is wholy contingent upon the fact that a material Universe exists. Meaning, if there is no physical distance by which to measure the rate of change, there would be no time. However, that isn't to say there wasn't an immaterial universe that existed prior to this, otherwise where would the pre-existing structure (blueprint) exist to give rise to the Big Bang and set the whole material Universe into motion? And what would be the difference between that and say, "rolling out the carpet" (so to speak) with its inherent design? Isn't that in effect what DNA does, the inherent blueprint or code that tells the body what to do? So, if all we have is the immaterial dimension -- ever wonder where we go in our dreams? which, are merely an extension of thought and of the same dimension -- then the only possible thing we can have in the physical sense is stillness which, is an expression of the moment and, extended unto Eternity.
