I must be a Seasonal Creature. This morning I got to thinking about the awesome size of the “Universe” and what might lie beyond. Did some research. But haven’t I written on this before? Checked. Yes I have! Here it is – read it if you wish. Am not bothered either way:

So, the “Observable Universe” is 93 Billion Light Years in diameter. Anything beyond that (that is part of this universe) is travelling faster than light so cannot be seen. But the Whole Universe is 14 Trillion Light Years Plus across per Ethan Siegel. And Cornell University talk of the Bayesian Model of The Universe, whereby it’s 23 Trillion Light Years in diameter. (I understand that a Trillion is a thousand Billion). In short, The Universe: IT’S BIG.
They say The Universe is 13.8 Billion years old. That’s from “The Big Bang”. And our Solar System, including The Earth, is but 4.5 Billion years old (“New Kids On The Block”!).
Our home galaxy, The Milky Way, contains hundreds of billions of stars. But The Universe is made up (at least partly) of about 2 Trillion galaxies. I am getting fed up of using the words “billion” and “trillion”!
But let me say again: “all” we are talking about here is that “Great Sphere” of “Matter” (“Light” and “Dark”!) we call “The Universe”. A sphere, regular or otherwise, that is expanding out from that original Singularity we term “The Big Bang”. And as I asserted in 2017, that may well Not be the Whole Thing!
As with talking about “God”, we soon hit an issue about “Definition”. The standard definition of The Universe is: “All of space and time and their contents”. This is where I have a Problem. Some use this definition to describe “The Cosmos” rather than “The Universe”. And in my View they are quite right to do so. For The Universe isn’t necessarily the “Whole Thing”. Even The Cosmos might not be Everything either!
Incidentally some have postulated that The Universe is Infinite in size. Well, surely not if we are talking about The Great Sphere, because that began an infinite time ago so can only have expanded an infinite number of miles. Now The Cosmos or “Existence” might be another matter… And that’s before we consider “Parallel Universes\Multiverses” etc.
As for the Future of The Great Sphere, well I go for the theory that it will eventually just “fade away”. Apparently it will go through a long “Black Hole” Period and in about 110 Trillion Years the last star will wink out. Then it will “thin out” even more. Way back in 2012 I wrote a short story about it:
https://paulbuttersmystories.blogspot.com/2012/09/our-universe-ends.html
I don’t hold out any hope for the “Future Implosion” theory. Nice notion but… So yes, The Great Sphere is not infinite and not eternal in its present form. Nor is it Everything in my humble view. In a way it’s not even the “Whole Universe or Cosmos”.
What lies beyond the Great Sphere? As with so many things, we simply just don’t know. I am missing some Champions League football now – much more important! Haha.
