"Space is big. Really big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."

- Douglas Adams, The Hitchhiker's Guide to the Galaxy

We will certainly watch it, thanks..

My question is, how could we ever really know just how big it really is? .. mainly because we can never look beyond past where the speed of light has limited the distance we can actually see/detect anything.

A big question about a reeeeallly big thing
