There's the rub. I really don't know. I'll do some reading and thinking and get back to you on that.
It might be expanding into nothingness, quite simply. It is hard to visualize though.
I think very few humans, and probably no one on this board (no offense), have the necessary expertise in cosmology to speak with affirmation here.
