But then I got another question for Sp1ke: How can the universe expand faster than c when nothing else can travel faster than c? Isn't the expansion of the universe just "everything" moving away from each other?

This is one of the most popular misconceptions about General Relativity, Cosmology, and the Big Bang!
If you can get hold of it - buy, or borrow from a library, the March 2005 edition of Scientific American has an excellent article by Charles Lineweaver on just this topic (
here is a more technical version). To get an overview of cosmology (and how GR is applied to the Universe), check out
New Wright's cosmology tutorial.
