lumens/light
If a source of light is moved from 3 units
away from you to 9 units away from you,
without pollution in the space between
you and the light. Why does the light
getting to your eyes drop by a factor
of 3 to the 4th power??? I just dreamt this
up??? See if you get the same result???

Re: lumens/light
Hint: don't think of a flashlight or a big light.
Think of tiny objects like stars in the night sky...
Because you might get a different answer either way
since, well I won't give it away.
