This is similar to a question you asked earlier because the main thing that creates an up or a down is rotation although a non spherical shape could also be a possibility and that is being investigated in current cosmic microwave background work. As for an inside and an outside we can infer parts of the universe that are and will always be outside of our regions of observation and can observe other parts (black holes ) that we are outside of. and I personally favour the possibility that our universe is effectively inside a black hole in another universe and so on without limit.
