    Everything in the universe reflects light. Except black holes. Only things you cannot see do not reflect light.

      except you can still arguably see things that don’t reflect light, if you were anywhere near a black hole (let’s imagine it has no accretion disk and thus isn’t surrounded by a bunch of light) it’d be pretty obvious what with the bending of light and how it’s a disk of pure blackness against the backdrop of stars.

        And you know, light sources. They don’t need to reflect any light.

              Yes. The flame is a cloud of gas and particulate heated to the point that it glows. It will reflect light. Just not a lot, and it’s also emitting enough light to overpower any reflected light in most conditions.

              And of course the candle itself reflects light.

                It doesn’t need to reflect any light though.
