User blog comment:The Milkman/Indoctrination Theorists Say the Darndest Things, Part II/@comment-1221773-20121204174646

Just an FYI, but there is a Codex entry in ME that gives specifics about the Citadel's size and mass: Citadel Station: Statistics. There's also an entry for the Crucible, but it's only a flavor text overview of what galactic scientists think it might do, and provides practically no "hard" information on its functionality.

I'm not entirely sure what you two are arguing about in that quote (the Citadel exploding?), but I did want to point out that in this one instance, that guy is correct (to an extent).
