I have never seen this explicitly stated as a definition of "the universe" and I'd like to know what you all think:

The Universe = the smallest perfectly closed system that includes me.

The universe is defined as everything that exists.

Universe is just a small region in the multiverse.

No, the universe is defined as everything. There is nothing outside it, by definition!

I've always gone with cfgauss' definition.

So do many physicists!

lol cfgauss. I'm not a physicist; I'm a computer geek and wannabe mathematician (with emphasis on the wannabe). I know very little about physics. It just seems obvious to me that the term "universe" means the set of all things that exist.
