It's fucking impossible to know nowadays, it has even gone into "this is so crazy that it can't be a troll" territory. I'm at a loss of words almost daily from the level of idiocy and ignorance that infects every damn comment section everywhere. The bar for most stupid imaginable is racing lower and lower every damn second, and it's already WAY beyond what should be possible.
I have a coworker who insists that global warming is a hoax because plants give off oxygen, not carbon dioxide. Can't even get a foothold in that kind of stupid.
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.
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.
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.
And things in itself that are too small to see with even a microscope do not reflect light right? Light might interact there but will not reflect in the usual sense, it can however emit light though. As far as I understand that is.
There is a lot to it wavelength, size of reflecting object (if it's smaller than the wavelength it can't reflect anything back also applies to emitting photons), reflectance or the fraction of light reflected at the surface of the object (the energy it obsorbs vs energy it kicks back), phase shift, if the photon is traveling from one medium to another with a lower or higher refractive index (redirection of a wave as it passess from one medium to another) it will change the oscillations (kinda like a feedback loop, photons effect electrons in the medium and electrons effect photons right back) like looking at a pencil behind a glass of water distorts what you see. I probably missed some things but I gotta admit it always fascinates me to think about light and reflection.
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.
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.
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
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.
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 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.
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.
I think the nutcake / troll was trying to convey that the rock is emitting light. Which is no less stone bonkers and a load of old cobblers, but here we are.
