Re: The universe is how big?

The diameter of the observable universe is estimated to be 93 billion light years (Gly) = 0.93E11 ly

"Observable" would appear to be a key limiting factor here. Are you saying that IS the size of the universe, or just the bit we can see?

And either way if positing a finite universe, what's outside it?
