    The reflection (scattering) of light can be seen on the picture they choose to make their point. Sure, the comment is correct that anything you can see scatters light otherwise you would not see it, but in the picture it is particular obvious where the light source is from the reflection on the rock.

      I wonder if they think “reflection” only means the kind of reflection you see in a mirror.

        specular, rather than diffuse, for reference

      It’s also a pretty dumb rock to use as an example. If the moon were that color it would be way brighter than it is currently. And with a rock as shiny as that you would clearly see a reflection of the sun as well.

      In real life the moon is about as bright as dark asphalt and because of all the dust it is very dull as well. So a matt black paint would probably be closer to what the moon looks like. Still bright as hell compared to the nothingness that surrounds it. Our eyes are also very good at low light conditions, once we get used to the dark a little bit of light goes a long way. So we can even pick out shadows in the moonlight on earth. A brighter moon would be annoying I think, imagine having some nights that look like early evening on a sunny day. But if we evolved with it we would be used to it I guess.

      Just like with flat earth the glowing moon theory fails to explain the phases of the moon or things like eclipses. And why the glow doesn’t follow black body radiation, but instead perfectly follows the tell tale signs of reflected sunlight, Fraunhofer lines and all. And where the energy to generate that light would come from, making something glow as bright as the moon takes a lot of power. And why that power source selectively lights some parts some of the time. And where does the sunlight that hits the moon ends up, if it’s not reflected.

      I would think it’s a troll, but these days you’d never know. Even if a troll for example claims vaccines cause autism for the grift, idiots still believe it.

    Do they think all rocks glow?

      I mean, technically rocks do glow.

          Surprisingly, this even applies to black holes (i.e. Hawking radiation).

          This was my first thought. Somebody tell this guy that not only is his moon model there glowing, but he is too!

          For bonus fun, tell him that he’s radioactive.

          It would probably be fun to have some instruments on hand to prove it to him as well.

    The only time something doesn’t reflect light is if it’s painted in that special black that’s even darker than vanta black, because that’s what makes it so black; it absorbs all light instead of reflecting any.

      And even that reflects a teeny tiny bit of light.

    NO! You can see things because light hits it, not becuz it reflects it STOOPIT ^\s

    If rocks emit their own light, how come you can land on them?

    If it doesn’t reflect light, it’d be black. If it emitted its own light then there wouldn’t be shadows in the craters of the moon and we also wouldn’t have moon phases. It’s hard to tell if this person is actually being serious because this is literally just entry level physics. Plus, we’ve collected moon rocks during the numerous moon landings.
