Babylon 5/Recap/S04/E22 The Deconstruction of Falling Stars

"What matters is what we did here, together. In a hundred years it won't matter who we were. They probably won't even remember."

- Delenn


 * Artistic License Astronomy: Sol isn't the kind of star that can go nova, and it certainly wouldn't be a mere million years from now. Background material/Word of God states this was artificially induced by enemies opening jump points inside the sun to siphon off its mass.
 * Bad Future: In 500 years Earth will apparently start another civil war that will reduce them to a medieval-esque society.
 * The End of the World as We Know It: Future humans, or rather their descendants, have left Earth for another world before Sol goes nova.
 * Shout-Out: The separatist culture of 2762 has elements of 1984, especially Newspeak, and the Feudal Future Earth of 3262 calls to mind A Canticle for Leibowitz. There's also something of an in-universe example in the form of the future human's Vorlon-inspired encounter suit.
 * Sufficiently Advanced Alien: Humans have evolved into this. They also wear encounter suits like their long-vanished forebears the Vorlons.
 * Meanwhile in the Future: The entire episode turns out to be this.
