The principle of entropy (attested to by the 2nd law of thermodynamics, for instance) says that every process occurring in nature occurs in such a way that the sum of the entropies of all bodies taking part in the process is increased.
A necessary corollary of this that it’s impossible for the universe to be
- infinitely old, and
- entropy to be operational all throughout that time,
since that would mean entropy would have had to run infinitely long by now, which would in turn mean that the universe would be in complete chaos by now, and there would be no me or you or us.
That means that age of the universe is finite. Modern astrophysics also admits that, theorizing the beginning of the universe to be the “Big Bang”. However, that still leaves unanswered the question of what existed before the big bang, and what caused it to happen. And also what existed before that precursor to the big bang. And so forth. So the real issue of origins simply gets pushed back a step, and is still unanswered.
Now we come to the question of the duration of the process of entropy in the universe. The logical way for the entropy to work and still be observable in this still-functional world is to have started with a high order / high organization (that includes the logical possibility of full perfection in order), and then to introduce an ongoing process of dismantling that order, or entropy, into the system.
If the system wasn’t ordered to begin with, there could be no concept of entropy, chaos, corruption, or destruction, since by definition:
- Entropy is something that introduces disorder into order
- Chaos takes an organized system and moves it toward disorganization
- Corruption takes something that’s whole and corrupts that
- Disintegration takes something integral and moves it toward a disintegrated state
For entropy to exist, order should have existed first. For chaos / corruption / disintegration processes to exist and be describable, organization / wholeness / integration must exist first. Without the initial state of order, not only disorder would not be possible practically, but even logically you wouldn’t even be able to conceptualize it, since the very concept of dis-order is predicated upon the initial existence of order.
So, entropy has to be a later addition to an ordered system. If we hypothesize that the universe self-organized over long periods of time, our hypothesis is predicated upon the ever-increasing order and complexity of information in the universe, which would require the process opposite to what entropy is to exist, to make that possible. That process is currently not observable, yet it had to have existed until every highly organized form (including self-procreating organic life forms) came into being.
Based on the above, I believe that the Biblical account of creation and of introduction of entropy into the world (a.k.a. “the fall”) gives a solid platform for producing a coherent set of answers to those fundamental questions that the modern science poses.
