The Big Bang Theory was created to determine how the universe was created. The "Bang" is an understatement though, considering that its more of an "expansion" after the initial giant explosion. Interestingly, if the universe continues to "expand", which it is, then we know that the universe is infinite. But, if it starts to contract at some point, we know it is not. Scientists say that the universe was nonexistent before the big bang. The universe came from a small amount of matter that was very hot and dense. A million years later the universe was cool enough to create hydrogen atoms out of protons and electrons that recombined.
