If energy can't be created or destroyed, then where did energy come from?

    I'm guessing the answer will end up being it was always there, or the laws of physics were different at the time of the big bang, but I'd just like some clarification.

    Yeah, I'm not sure anyone really knows. Probably some good competing theories out there though.
