It has dimensions, an age, it can be expanding, and has limits it can be measured. And if you truly have nothing outside, I don't see where the uncertainty principle and thus zero point energy apply. Even then, you are basing this assumption on a very small sample, surrounded by matter, energy, and a lot of somethings.
If the Universe is finite and expanding, what is it that it is expanding into it?
