If our distance from a light-radiating body, that (like a distant star) is nearly a point source, is doubled, the intensity of light received from it becomes (nearly exactly) one quarter of what it was before.
Suppose that it was possible for a star to be stretched across space in a thin incandescent filament that, for all intents and purposes, was endless.
What kind of mathematical law would then relate the intensity of light reaching us from this filament to our distance from it?
