You will learn a bit from asking this question but perhaps your opening post needs a bit more in it to get it started.
For one thing, many here would be interested in where you got your ideas about what the big bang actually is and what it predicts about what the universe would be like. It would be useful to supply your source for thie "information".
If it is your own idea then perhaps you could explain a bit about what you think the "BIG-BANG theory" says and how you arrive at your conclusion from that.
Since your errors lie in the basic understanding of the concepts it would help people straighten you out if you clearly state what you think it is all about.
