Either red shifted out of sight or not enough time elapsed since the beginning of the Universe, either way, there are dark corners of the universe humanity cannot see.
Speculation on the size of the universe remains speculation.
Thank you for the response. How do we know there are only "dark corners"? The map of the universe seems curiously symetrical to me. What if the extent of what we call the universe only represents 30% of what is actually out there? It would seem that detail would change a lot of calculations.
I suppose we just have to have faith.
