So it's fair to say, there is no begining, there in no end, and there is no centre? Just looked a 3d map of the known universe and from what I read that is 1% of what it actually could be. No one really knows the extent, or how it works, re the ballon theory.
Because we are limited in our thinking we find it hard to understand infinity. As everything we deal with has a beginning and an end?
