      Well you can, but it would involve looking straight at the sun or a light bulb which you shouldn’t do because it might damage your eyes.

      Everything else you see only because it has reflected light from somewhere else.

      Steve’s right… also while looking straight at the sun isn’t a good idea, starlight is (mostly) not reflected! especially if you’re looking at the stars from space where you don’t have a big atmosphere to get in the way 🙂
