        It’s condensed content with simpler terms and plain English, which is helpful for those who aren’t native speakers, like Gamba said.
        Simple wiki also comes in handy in topics like biology, which can have very specialized vocabulary.

        But in this context, the people who unironically believe in things like the moon not being a reflector can’t be reasoned with. They won’t change their mind no matter how simple English you explain the fact.

        They should just be rugged individuals and use a bag, it helps get over the ingrained Marxist socialist brainwashing that will get them fake breathing as soon as they pass out from the overwhelming yearning to be free.

        The bag on their head shows they must break the yoke of communism and be independent

    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.

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

      The event horizon isn’t a physical object. Does a singularity reflect light? (I’m guessing it’s still a no)

        Once something moves past the horizon any light that bounced off it would be pulled towards the center with it. Effectively making it non reflective. It’s possible all the energy from being crushed into a singularity causes a glow around it, like the disk around the outer area of a black hole.

        If that’s the case, the glow itself would also be sucked immediately into the singularity. Maybe for the shortest of time, on the tiniest plank scale, the singularity produces light.

          The accretion disk would emit light as particles were accelerated into the hole. Plus there would be hawking radiation from the evaporative process black holes have.

          The only form of “light” (it isn’t really light but radiation, which I’d basically the same as light just that it has a different energy value etc) is the hawking radiation.

          The event horizon only obscures objects that are inside it, it has nothing to do with reflectivity of the object itself.

          An observer situated between the singularity and an object within the event horizon could still intercept the light reflected from said object.

            Light bouncing of an object is what creates reflection. The only way to see reflection past the horizon is to be closer to the singularity than the object you’re looking at.

              That is what I said, yes.

              The point being that the event horizon deals with the structure of spacetime, while reflectivity is a material property. An object doesn’t get painted with vantablack when it passes the event horizon.

          No. An object within the event horizon is still reflecting light just as it was before falling in. The only difference is in relation to where that reflected light can or cannot go from there.

        Never seen a singularity so would have to agree it doesn’t. Visible Event Horizons are made up of matter that does reflect light, but if there is no matter involved only light you would likely see is distorted as it passes through it from other sources

          No event horizon is made up of matter. Do you mean the matter around and behind the black hole, by which the location and size of the black hole can be inferred?

      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.

    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.

      Black holes don’t reflect any light at all as far as I know. They do emit some light via hawking radiation, but that’s not really reflecting.

        Honestly, it sucks. I have never been able to take advice from either of my parents as an adult. Of course as a teen they seemed dumb to me, but even then I recognized that I was a teenager and that perception was typical for my age. But they never got any smarter. Frankly, the older I’ve grown, the more like children my parents seem to me. As a kid they always told me I was super smart. Now as an adult, do they listen to me if I try to correct their mistakes? They do not. They’ve been suckers for cons my whole life.

        And no, I’m nowhere near as smart as they led me to think.

          My dad was the dumbest man I ever knew and he still had wonderful advice sometimes.

          I mean, I can say that to you here and you can only imagine with the limited data, but my dad was duuuuuuumb.

          There is value in our idiot parents. We just have to find it.

              Yeah my dad never bothered me with that, but boy oh boy my mom does.

              That was the biggest part of their struggle. My dad was a wild animal and my mom should’ve married a preacher.

              She’s married to a man who sees the world like she does now. He’s a good dude and he’s perfect for her. She spent 30 years trying to make it work with my dad.

              I like my mom’s husband, but stories could be written about my dad (wasn’t my father, just raised me).

              He lived a life that would make some award winning movies look like Sesame Street.

          While it’s certainly possible for a person to be stupid, I find that very often it’s more accurate to describe a person as ignorant. In this context, I don’t mean that as an insult; I mean literal ignorance, as in the described person has not been exposed to relevant information, or possibly has been conditioned not to accept that information if it is provided.

          It’s anecdotal, but most stupid people I meet aren’t stupid, just missing or unable to accept certain information. This especially applies to young people.

            Ye, I agree with you. I made the comment as a joke, but I don’t actually believe these people are stupid. This is a generalisation, but I think they’re largely uneducated and brainwashed, but still very intelligent, and curious people. You can see this in some of the experimentation that they do that’s really sound from a scientific method POV. The internet is littered with flat earthers disproving themselves.

            The best ones admit they’re wrong, and abandon flat earth. I have nothing but respect for those people.
