Thanks guys that has given me a new perspective since in school they basically make it seem as the universe started as nothing and then a large event happened and it has been expanding ever since. Just never made since to me to me since matter can't be created.
So I've been out of school for about 10 years and have always wondered about the Big Bang theory and want someone to really clarify it for me if they can and if it is strongly supported by most people or not. I have the basic idea of how it is explained from school but never attended a class that really went in depth about it. If someone can do this I will explain my thoughts on why it doesn't make sense to me.
