Is there any theory to say if expansion started with a finite seed and propagated out at a finite speed vs somehow happening everywhere at once? I know the layman's phrasing is that expansion happened everywhere at the same time. That might just mean that the very small part of the early universe that today is our observable universe expanded all at once as nearly as we are able to observe, or it might really mean that somehow a dense universe of infinite expanse expanded everywhere all at once.
