A poignant thing about such objects is that our descendants will never reach them (unless FTL travel is a thing). Due to the accelerating expansion of the universe, even a beam of light directed at it will never reach it.

Actually, you could comfortably reach quite a lot of points in the universe in your lifetime, provided you'd have a free constant thrust engine. This one not, because it's out of our light cone.

Sure, "quite a lot" in an absolute sense, but the fraction of the visible universe that's still reachable is quite small. IIRC, something like 4%. Don't quote me on that.
