If it makes you feel any better, the concept of "at the moment" doesn't really have a meaning at relativistic distances - simultaneity isn't defined. In any sense that practically matters, what Sagittarius A is up to "right now" in our frame of reference is what we see it doing in our telescopes. Although there is a sense in which it happened 26400 years ago, any event further into the future than that is, for us, just as nonexistent as next week.

Ironically, HN seems to be confused as to whether you made this comment 15 minutes or 1 hour ago, depending on whether I'm in "Add Comment" or the main thread. Different frames of reference, perhaps?

(edit: all comments are incorrectly marked as being 20 minutes old in the main thread) (edit2: and my comment is only visible to me, apparently. HN is broken.) (edit3: huge lag between edits and public visibility of said edits from a non-logged-in browser)
