Two Birds Uncertain About Heisenberg

One day God came into His living room, which is the universe, and exclaimed: "My Self! This place is a mass!!" He instructed Gravity to clean up after itself, or no TV for whatever was left of eternity.
So, for the last 15 000 000 000 years Gravity has earnestly tried to make the universe into a vacuum and pile everything neatly into one place. This turns out to be a full-time job. That's why Gravity can never take a vacation, grab a beer, and watch black guys fight viciously over an inflated bladder.

I could tell you why Gravity can't finish the job, but you won't believe me. Oh heck, I'll tell you anyway. It's the Uncertainty Principle. (Which I now have to explain to you.) It goes like this:

These two birds illustrate the simple truth, that two things that are equal and opposite add up to nothing.
Well, not really nothing.
There is the illusion of duality.
