Buddhism about the Big Bang and Science in general

What did Buddha have to say about the creation of the Universe, if any? I asked a monk after a discourse, and he said that there is a reference to continuous Big Bangs, not simultaneous, but one after another. There have been many such Big Bangs before? I don't understand though. Is this true? This is a slightly broader question than my previous one but is related. Does Buddha have anything to say about scientific advancements? Is there any need for Science in Buddhism? Is Buddhism too broad and philosophic for Science to explain logically or is this an excuse for not being able to explain certain phenomena scientifically?
