Someone sent me a link to this site: The Scale of the Universe
Which shows in graphical form the scale of the universe from the very small (Planck length) to the very large (the size of the universe)
Now for the visible size of the universe it of course states the usual approximately 14 billion light year size we all know of, but then it goes on to the estimated size of the universe as 93 billion light years.
How do they obtain an estimate of what is outside the visible universe if it is unobservable?
