If the theory of our universe being in the shape of a torus is correct we are near the end of this universe!
So far all the theoretical data holds up, explaining the rapid expansion during the beginning of our universe using gravity and not "dark energy". As well as the reason we aren't swimming in equal parts anti-matter, the big bang ejected matter and anti-matter from it's two opposing poles (hmm this sounds familiar). Using the observed period of early rapid expansion the resulting estimated time we meet up with our anti-matter twin is only 1.8 billion years! The portion of this theory I find comforting is that when we collide with anti-matter on the outside of the torus shape the resulting collision ends up being the birth of a new universe.
I like to picture it as the universe using a wave pattern that's mirrored by it's anti-matter twin, the vital wave pattern that we see repeated in different mediums that were born billions of years apart (light and water). It's an exciting theory and much more comforting than the big freeze. For those of your out there that got a little wet or hard reading this check out Howard Bloom and his book "The God Problem", the book presents a fascinating take on our history that I wasn't aware of and paints a beautiful picture of reality using patterns.
