Oops, I typed the link name in place of the path (now edited)...no, I meant this link:
Horizons
|
They way I recall it is that such a horizon does in fact exist in FRW cosmologies IF the expansion of the universe is acclerating. (Current data suggests that this is the case). I suppose I should go look for some references to support my recollections.

You're right, I hope I didn't give the wrong impression here...I don't have so much faith in the standard model that I would confidently extrapolate it to t->infinity.
There
may be an event horizon. We are by no means confident that this is the case.

If the expansion of the universe is deaccelerating, we will (again IIRC) see all of it eventually.

Yup. And if it accelerates for a while, then decelerates (like the post-inflation universe), then an event horizon calculated assuming [itex]\Lambda CDM[/itex] would be incorrect. It's for this reason (among others) that I view Mike2's entropy arguments with great suspicion.
