James of Silver Spring, MD asked: The universe is everything. And the universe is expanding. What is the universe expanding into if the universe is everything?
Thank you for the question, James. This is indeed proof that I don't know everything. I am still stuck on the question "what was there before the universe that allowed something to go 'bang!' in the first place?".
Personally, I like the universe-in-a-grain-of-sand theory of everything. It is infinite both ways with no beginning or ending.
