50 Simple Proofs, God is Imaginary

[theVOID]

Maybe conclusive to you (and many people)... but until we know for fact what did come before (if anything): there will always remain some reasonable doubt. (Also, i don't get how entropy equates to closed system... in some iterations of the universe: it could be true... but it is an assumption that this iteration is not one of many envisionable systems in which entropy is just a stage in the system.) The question of 'How did the Big Bang get there?' becomes all the more important if this universe is not the original.

I'm not arguing that it's a certainty, only that it's very likely.

There is always the possibility that this iteration of expansion is the only one of an infinite possible number of outcomes and just happens to be the first in which there will be no collapse.

Entropy is defined as the amount of information needed to describe a system, and if entropy is increasing then the system is growing in complexity - it is a law of thermodynamics that entropy will only increase in an isolated system, and this is where the conclusion starts to be drawn that the system is finite (though may be infinite in terms of space). If you reverse the expansion of the universe to a singular point you also simplify entropy in reverse until the point where all matter and energy in the universe is a single unified force, the singularity - We know that the singularity is not infinite as it is no longer, and we know that since it is also not infinite that it can't be the original infinite system. That to me suggests a parent system which would be cyclic, where entropy is in a constant state.

As for 'How did the big bang get there' is anyones guess - that is beyond our current understanding and possibly out of reach all together.
