I think the consensus would be be that the question is a-scientific. Absent data via a test / experiment that can be repeated, there is no science to be done.
There is somewhat a basis for the universe being larger than we can observe, and that the parts that we cannot observe are about the same as what we can observe, which is, as I understand it, physics works the same everywhere, and, we do not have a distinguished place in the universe. Note that those are general principles which have worked so far, but are more useful guidelines than physical rules.
