You'd have as much luck "meeting up" in Super Mario Brothers. There is no real-time networking traffic and no player models in NMS. The "whoops, there must be a bug" reaction is a baldfaced lie.
And the claim that it's unrealistic to reach the same place are BS. There are not 2^64 stars in the starting galaxy (Euclid), only a few tens of billions. And everyone starts out roughly the same distance from the center, which means that they're all in a narrow spherical shell containing only a tiny fraction of those stars. It's rare in the game to not come across systems discovered by others, even when you're not trying.
(The 2^64 claim is valid, but only in that there are 2^32 galaxies)
As for day and night, the game is totally inconsistent about that. You can approach the "day" side of a planet and have it turn out to be night, and vice versa. Really it's hard to think of something in the game that's *not* totally glitched. Even keyboard support is glitched - punctuation in naming discoveries gets mixed up. I mean, how the heck do you even manage to mess up something like that? Oh god, let's not get into the naming filter that lets through names like "Cum Mountain" but bans words like "Cousin" and "Can't".
