Lies! The universe is only 6000 years old! That means the entire detectable universe must be within ~6000 light years.

I kept on expecting it to continue to back up only to reveal the universe to be an atom in a speck of dirt in the finger nail of some alien...

What lies beyond the edge of the expanding universe?

It boggles the mind to ponder it...anyone know of any theories?

^ I'm reading a book right now called: The Fabric of the Cosmos" by, Brian Greene. It's sort of a "dumbed down" physics text. (using examples from The Simpsons no less) I think the general consensus is that either spacetime is infinite or curved. In either case, it would have no edge. Of course if it does have an edge, we can't see it anyway which just leaves it up to your imagination. More universes? Green cheese?

I'm all with rotten on this one though. I love to think of the idea that our observable universe is just part of a molecule in an even bigger one.

Or maybe it's curved just the right way so that WE are that molecule. Maybe if we can observe smaller and smaller and smaller objects, one day we'll just see ourselves staring back?

^wouldn't be the first fractal in nature...
