So, I've been looking for this answer for a long time and nobody can give me a good enough answer. Although it's simple enough, I just want an answer so I can do a term paper. So here's my question: What exactly is the big bang theory? I know the effects now, but I want to know what happened 20 billion years ago. What started it? What went on? and Will a big bang ever happen again? Thank you for your time and for your answers.

Check out the book by Stephen Hawkings entitled "A Short History of Time"

Easy reading and treats this subject well.
