In this question I made a quick comment that there is an analog of "Gauss's law" for GR at large distances, that it is called the definition of the "Hawking mass". Further, I commented that it is not reasonable to expect Gauss's law to work in general, because the group is not commutative.
Now I went back to turn this comment into an answer. I suspect David erased it. How am I supposed to know what else is being erased without me knowing about it?
What is the explanation for the missing comment? Somebody deleted it, and I don't think it was me. I wanted to have it as notes for a future answer, and now the future is here, and it's gone (although I remember what it said).
