The Universe has an underlying essence; this essence, as a whole is ever living.  But within the whole, there is continual becoming, growing, perishing—its dynamics.  What people name God, an empty word as far as explanations for the universe go, is now slowly being replaced by this Essence: some cll it super string, some brane—all forms resulting from chance quantum fluctuations as predicted and required by the Uncertainty Principle.  It is the dynamics of this Essence that gives rise to Universes.  We still may not know why is it these fluctuations actually exist or what they really are; to the laity they will always be as empty as God, perhaps even more so given their impersonal nature to us (unless, of course, our reverence for God is replaced by our awe at the essence itself).  We know they are forms of energy, and we can describe their interactions with mathematical formulations supplemented by empirical observations, but we can never “know” what they are (or know know—whatever the hell that means).  What is energy after all; it’s nature?  Our definitions will always be functional and/or descriptive and explanations will resort to the conversation of some law (like the Uncertainty Principle) or the other.  But the essence will always remain a mystery, just like God.  Perhaps our brains are simply not wired to grasp all of nature, in all its multidimensional grandeur.  That even our brains and systems of logic embedded in them have limitations or are simply not the only systems of logic possible.  To think three dimensionally and to operate within the crude realm of cause-and-effect makes it dumbfounding to grasp the quantum world and relativistic events, hence the mathematical abstractions we resort to enable us to describe the world and make some sense of the “order”/order that is around us.  Perhaps only to describe something is to know it.  That may be the limit of our knowledge and asking why may be absurd, because once we describe something, what more can we do to further “know” it or “explain” it.  Go Superstrings!  Perhaps this whole paragraph is a misunderstanding or the inappropriate use of language, given the equivocal nature of words.  Anyway, it is interesting to note that the Greeks already had a similar analogy of this Essence; they called it Being that has the ability to manifest Perishing and Becoming but IT itself remains unchanged and unchanging.  Every philosophy to date and even its empirical offshoot, Science, may be grounded by the tensions that exist between Being and Becoming—even our moralities and systems of Justice play out this duel.
