Gravity Works
The invocation "gravity works" is a shorthand I came up with years ago.
It means: A thing that is, just is. You can't explain it away. You can't argue that it violates some theory. You can't condemn it as heresy and disappear it.
Gravity doesn't care what you think of it. It doesn't care whether you think of it. It doesn't care if you disagree with it. It doesn't care whether you know about it. Ignorance and opinion hold no sway. It is impartial and unforgiving.
It is also shorthand for "what you think doesn't change what is."
It is shorter than invoking the laws of thermodynamics, or mass-energy conservation, and it scans better.

Or as Philip K. Dick put it: Reality is that which, when you stop believing in it, doesn't go away. (see BeliefsCreateReality)
Also, Batty said "Gravity Works!" while falling out of a tree in Ferngully: The Last Rainforest
Sounds just like Werner Erhard in 1975!
