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?

As the saying goes, "there are 2 great unsolved problems in computer science:, naming objects, cache invalidation, and off by one errors."
In case you haven't noticed, to reduce server pressure, a logged-in user sees comments in real time, but a guest only sees the cached version of the page that only updates slowly. When Hacker News sees an explosive amount of traffic, logging out is a way to help. The last time it happened was when Donald Trump was elected.
