Hi all, i have a question about the big bang, it might be dumb i dont know much about science. Anyway here is my train of thought. 1. Matter cannot be created nor destroyed and therefore everything that exists today has existed for an infinate amount of time in the past and will for an infinate amount of time in the future. 2. The Universe, the big bang supposedly has an age in the billions of years. 3. If the big bang has an age and is a once off thing then what is the chance of the big bang happening at any point in the last 20 billion years if all the matter making up the universe has been around for ever? If this is the case the chance is infinatley small. 4. Therefore it seems to a layman(me) that the universe is in some sort of pattern and maybe a big bang pattern. Maybe our universe is imploding then exploding then imploding, exploding and so on. Maybe it has done this forever in the past and will do forever in the future. Something like this seems more likely to me than the big bang being a once of thing that happened at some point in the last 20 billion years out of an infinate past with the chance of that being infinatley small. Could this be the case and is any of this valid?
