If this is considered a "cosmic belch," would the "Big Bang" be considered "The Great Fart?"
Asking for a weirdo friend.

First of all, the Big Bang wasn't very big. Second of all, there was no bang. Third, Big Bang Theory doesn't tell you what banged, when it banged, how it banged. It just said it did bang. So the Big Bang theory in some sense is a total misnomer.
And as a consequence of this misnomer, most non-cosmologists continue to picture it as a big explosion. Though they forget that explosions are destructive rather than creative. The Big Bang being an explosion just wouldn't make any sense. It wasn't an explosion.
First there was nothing ,,, then there was everything.
Personally, I like to believe the world was dreamt into existence.
