Premise 1: Entropy always grows (second law of thermodynamics)[/qs]
Wrong, entropy can decrease, at least, in an open system. And even in a closed system, entropy can locally decrease.[/qs]
But the average trend will be towards entropy, otherwise the second law of thermodynamics doesnt goes ...(what is the right word? Up? count?)
But premise 1/2 can be replaced by anything that proves the universe is not infinite, like: if the universe excisted for an infinite time, we could not have a tomorrow. As we would have more than infinite days.
[qs]There is no evidence for this. Further, "cause" implies a "before", there was no "before" the big bang, just like there is no "north" of the north pole.[/qs]
But the question I have, is: what caused the big bang?
Because it either must have a cause, or a supernatural power created it. (To translate in your example: When you're reached the north pole, you've found the cause for it being the north pole the magnetic field. If you've reached the big bang, you would find the cause.)
Oh and you're right PaulK. I ain't a native English speaker, I agree with you that begins fits the context better.
