It suggests that our universe arose when two or more dimensions collided, which would account (at least partly) for the uneven distribution of matter within the universe. Another theory is that the Universe is simply timeless, and the Big Bang was a result of the collapse of the previous universe. There is currently strong evidence against this theory, but it remains on the table nonetheless. Some have said that our universe is the result of beings of other universes creating it, which isn't entirely unrealistic. Again, the M-theory tells us that we could very well create a universe separate and independent of our own with relatively little effort. Whether or not this is true is another thing, but interesting to think about.

EDIT: And what on earth do you mean by, "what came first the cause or the effect?" S'plain.
Big Bang coming out of nothing is a logical paradox.. which most of science can't answer. Though it becomes logical and obvious in digital physics, but it still avoids the masses..
