RE: But if the global

But if the global geometry of the universe is an ellipsoid then that means it's finite – which to me implies an infinite amount of remaining spacetime that more than dwarfs the universe nearly unto insignificance, and so what might such an excess be filled with? I suppose it could be a type of Multiverse ...

I had realized how large this would make space-time, but I just assumed that the density of matter would be about constant throughout. Are you saying that there are large voids of emptiness that separates different groups of matter, and we should consider each group of matter it's own universe?

To me, the nature of the interaction between light and matter, on the smallest scales observable, implies a stranger and singular (invariant) solution that is 'already there' in infinite extent. Not so much things like entanglement, but more what happens to time and distance when velocity equals the speed of light – things are connected on levels (or dimensions?) for photons in ways that allow for taking all possible paths - as if distance and time weren't there somehow ...

I have said this here before, but doesn't it seem like we are missing something?

I was just trying to say that it's difficult to compare a universe that's finite in size, no matter how large, to the remaining amount of spacetime (infinite in extent) that would exist beyond it. Fortunately, a sterling job of it has been done – see this really good SciAm article, Parallel Universes

Sure, we're missing which part of not even wrong is exactly right. I think if the universe is information in the form of bits then intelligence becomes synonymous with knowledge, both being defined as “sets of properly ordered bitsâ€. There would be a finite number of sets and each would have a finite number of elements since all other orderings would be either less intelligent or false/incomplete knowledge. I also think that when it comes to the universe repeating itself, it happens early on, with fundamental particle/wave-energy, then with atomic particles, solar systems, galaxies, clusters, groups, and ?? Truth is something that's universal in extent, along with an infinite amount of space, time, and energy – to experience it all in finite measure, I guess that's life, I dunno :)
