One of the MadScientists wrote, "Two, you might look at the Hubble expansion 
and realize that there may be lots of areas of "our own" universe that are, due 
to the expansion of space-time, forever cut off from us (i.e., expanding away 
at greater than the speed of light). Clearly science has a lot of trouble with 
this one, because such areas are, by definition, unobservable and thus in one 
philosophical sense beyond the realm of science (which is based on 
observation)." Here

Which made me wonder - isn't it that we CAN observe the area, just the 'past' 
of the area?
