NOTE: I have seen this topic at ACF, which has ended up in some terrible flaming, and moderator "he says, she says". I would like to remind members to please not get carried away and not insult anyone by calling them "geniuses" or "fanboys", etc. I'm glad it hasn't happened here yet, but if it does happen, I will not hesitate to use the warn button.
There are often inconsistencies that are often not really explained or dismissed in episodes, video games and the like. That's most likely why they don't happen in real life. For example, the inconsistency with Lisa's age in the Simpsons. As with Supernova, and the planets miraculously appearing again, it's another one of those inconsistencies that may not require an explanation. If you can disqualify in battle moves because they are inconsistent, you may as well disqualify that attack from ever happening because it's not logical. However, that is an attack that Sephiroth uses in the game, and with regards to the physics behind a Supernova, we're not speaking of the sun in the solar system as we know it; this is a different universe, and even so, it's just a fantasy game; a mere fiction that doesn't have to follow any sort of real life science that we know.
