Hi, I was wondering if anyone had any thoughts on why the inverse square law is two. I have read that it has been tested to 1 part in 10^15. I am not sure how that was done.
I'd bet someone will come along and not read and check out #1 answer and try to improve on the excellent explanation already available for the trouble of reading it !

I think that it should be possible to make John's excellent answer more difficult to understand if we just inject a little string theory and other astrophysical flotsam into it:
1.) It is only true because we perceive the arrow of time to be unidirectional.
2.) It is only true because space is not significantly curved in our neighborhood.
3.) It is only true because we insist on pretending that our universe has only three dimensions.
I need more coffee, but I'm sure there must be hundreds more ...
And, as it happens, my biology background seems to qualify me to improve on this in a minor way - NO, the skunk's odor will not obey the inverse square law. Debate ended. (I can provide proof to any doubters, by the way, I have a skunk available...)
