Umm... I hadn't seen that joke, but if Chara knew Star Wars, then that means Star Wars already existed in 201X (when Chara fell into the Underground). And I seriously hope pollution never does block the sun, because that would be the end of humanity.

I didn't know Sans could get numbers wrong. I'll check his Wikia page to find outthe details. But in any case, the amount of information he can get by just looking at the protagonist is incredible.
