Welcome back to "Doggerel," where I ramble on about words and phrases that are misused, abused, or just plain meaningless.
This short Doggerel entry falls more into the useless pet peeve category. "Universe" is a word that's been diluted by science fiction and fantasy. Woos with delusions of coming up with a Theory of Everything without resorting to math have probably helped it along. The real meaning of "Universe" is everything. There's only one everything. Because of that dilution, when thinking of combining D&D campaign settings and such doing crossovers, I often have to start using weird words writers have come up with like 'multiverse' and 'omniverse' to describe the whole giant mess.
You can expect later entries on specific uses of 'universe' woos use, since those will generally fall into specific claims.
