comment Does space expansion imply light will *never* reach objects currently distant enough?
Thanks - wonderful, detailed answer. And I was right, expecting that the event horizon lies somewhere between 1 and 2 Hubble Radii - from these calculations it seems it's at 1.15 its size. I still can't quite feel why the two approach asymptotically - in particular, why the Hubble Radius is a curve - but I bet that's a subject for a different question...

So, I should understand this that near centers of mass the space is so curved and messed up generally that the expansion has no chance to act - as if, not particles, but the space itself had to have a certain escape speed to move (expand) out of the inhomogenous areas? Replace the ants in "ants on balloon" models with specks of glue?
