    Well, not if you define darkness as the total absence of light

    Define light, define darkness. When you observe the sky in the night you are looking through a dark space that is full of light - it is just not dispersed and as such not visible to your eyes. But put something large and reflective enough in the place you are looking at (like Moon) and you will say - how bright!

    I guess this does sound like nonsence but without light our eyes couldn't see darkness

    Darkness is the absence of light. One does not see an absence, so your statement does not seem to make sense.

    I guess what the saying, "even in darkness there is light" is really saying is, open your darn eye's! and has nothing to do with actual light and dark. I think thats what I meant, Ya that's it.

    Philosophy aside. Even in a vacuum 'darkness' there are quantum fluctuations which you can measure with the Casimir effect. That doesn't translate to 'light in darkness'. But there is 'something'. Is that what you are referring to?

    Is the darkness you speak of a man-made environment - designed to keep light out? Or, are you thinking about the darkness of space - where there are distant objects capable of emitting light?

    The OP seems to have been a drive-by poster

    Unfortunately, I've read a few other threads that seem to fall into that category.
