Title: The big bang theory says space expanded, what space did it expand into?

The big bang theory says space itself expanded, what space did it expand into?

Is there any evidence of a medium/space of which space itself expands upon/within?

The Big Bang Theory is an idea of the origin of ALL matter.

If an object grows, it first needs room or space to grow. But if space itself (which contains everything) wants to expand, there's nothing in existence for it to expand into, right?

I think that the term "a pri·o·ri" might apply here. My premise is that that the universe has always existed, and so space too has always existed. I see no reason to think that space hasn't also always been infinite.

Theoretic deduction is reason without facts. I thought that's what exactly most scientist wanted to avoid.

And besides, if you believe the universe always existed, you don't believe in "an origin" of all matter.

I don't agree with your take on "theoretic deduction", but so what :) .

True, I don't. In a universe that has always existed, matter and energy would have always existed too. There would be various circumstances where matter would evolve into energy, and energy would evolve into matter to make change possible.
