What gets me going, is if the universe *is* a universe, by definition it
must be infinite, surely? So how can it even have a size?
The surface area of a sphere is finite, even though it is unbounded.
I should have said a *known* size.
Obviously we can only measure what we can see, but as is already shown,
by the missing mass, we can't see it all.
