The problems of big bang theory. What are they?

Hi, Tyberius Max,Your entire argument is based on the Fallacy of Composition, just because things inside the universe behave in a certain way gives us no reason to suppose that the universe itself does.

That's Mr Jack.Yes, that's exactly what I'm saying. Arguing that because everything in the universe has a cause*, the universe itself must, is a logical fallacy. This doesn't mean the universe didn't have a cause, it means we can't know.* - and, in any case, not everything in the universe has a cause, as was noted earlier.

A small point, Chiroptera, but we don't actually know that. Current physics ability to describe the big bang breaks down (extremely!) momentarily after the singularity, so it can't track back from there; however, both String Theory and Quantum Loop Gravity can be traced back through t=0, and predict that time continue on the other side of the bang - that there was a before the big bang.

As I understand it they predict that the before and after are mirror-images of each other; so time is infinite in both directions analagously to positive and negative numbers.

Pretty much year, the direction of increasing entropy is reversed.

Yup, you want to believe in a "god" that created the universe, that's fine. Nothing against it. No logical argument can be brought against such a being.It has nothing, what-so-ever, to do with the kind of personal, intervensionist, god that Christianity (and others) claim exists.
