It's funny how if you consider only the facts we have in astronomy, we really don't know anything about the universe. Dark matter, energy, flow (flow is a new one to me). Sure, they have evidence supporting their existance, but we haven't a clue what they really are or where they came from. Worst of all, the three are all seperate phenomena, despite all being "dark". At least my Kirby theory unites everything....
And there are probably even more mysteries in the universe that we don't know about. Will there be dark heat? Dark electromagnetism?
... in the hope that it would provide 2 minutes of amusement for someone.
The Universe and everything
