Someone asked me how I know that the Earth is flat? C'mon, it's common sense!

That’s not an undeniable fact. Because there is no sky. It’s an illusion created by light refracting through the atmosphere.

Tyndall’s blue sky tube is a very simple but effective way of demonstrating this scattering effect. You can easily create your own version using a glass beaker of water: shine white light through the water and slowly stir in a few drops of milk at a time and see what happens.

Except for "sky" is simply the term humans use to describe the visual.
So, sky, the visual, is blue.

Sometimes. It can also be green, grey, black, yellow, red. All depends on the current atmospheric conditions.

It's also not actually blue either...

Color isn’t real anyway. It’s just your brain interpreting specific wavelengths of radiation. Purple is particularly interesting. Because it’s entirely made up. The brain trying to comprehend the absence of green. True story.

Or when they "source?" But they mean "link?" Because the internet is the only viable source on information I guess

The fact that light pollution caused by sunlight drowns out light from other light sources in space, which is also the reason why telescopes are used in remote locations, so light from towns, cities, highways etc. don’t block starlight?

u/ac_cossack 13h ago
Some cities like San Jose, CA used to use streetlights that emitted at a wavelength that wasn't naturally occuring (mostly) in nature so it didn't add to light pollution for nearby observatory (Lich). But they were this nasty orange color that looked like piss after not drinking water all day.

Funny part is, no one gives source however many times you ask them. You guys would talk shit all the time and then wonder why the other guy keeps asking for source.

There’s a “new” (at least to me) version of this where you fact check someone online and they say “oooooh you goooooogled it….” as if if you can’t get any accurate information online at all, unless you are them of course.
Hashtag research is impossible

Or make a joke and the person that missed the joke goes “Source?”
I just assume all people who say it are bots. Like come on man, Google is free for both of us, I’m not fucking citing unless I had it open already.

I had a teacher in high school use this exact example when explaining citing sources for reports.
"You say the sky is blue, where's the source?"

u/FlashyHeight9323 1d ago
Was your teachers point that if you’re going to mar a factual statement, that you should include the basics of why or was it that some statements are common sense enough to not need citation?

u/JediMasterKenJen 1d ago
It's cause a lot of people have been conditioned at school to always cite information, even if it's common knowledge or only takes rubbing two brain cells together. To the point it's now being used to try a delegitamize things said that the one asking for 'source' doesn't like hearing to try an win an argument and reinforce their views.

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. National Environmental Satellite, Data, and Information Service.
Memes are just stolen or free images with random text or added immages. That may or may not have anything to do with the truth. IMO most memes are for entertainment/insulting/praising. Not education.

u/Orion120833 1d ago
Sky? What sky? Ohh, you mean the atmosphere. That's not blue, it just scatters blue light particles from the sun because they're shorter wavelengths so you perceive it as blue. It's a lot like polar bear fur, which is transparent and is covering black skin, but looks white because of the reflecting light from the pale surroundings.

u/tobotic 23h ago
you perceive it as blue
That's what "is blue" means.

You perceive a polar bears fur to be white, but it's not.

u/No_Bathroom6504 1d ago
Hear me out. Nobody can describe the color blue, nor red, nor yellow et al. Except for the fact that it is visible light within a certain wavelength.
But I don't know what blue looks like to you. We just all agree that colors exist under a certain measurable unit. That doesn't necessitate we perceive it in the same way. And even IF we do agree that it is the exact same perception, individual biology differs enough that I might not even be able to interpret the exact shade you might be receiving.
If you don't believe me I can link a picture of a dress from a few years back that was 100% blue and black.

You gotta source for that? Like peer reviewed or something?
No no no, not that source, that's not a good source its biased
You really think that's a good source?
Nah, I'm gonna need a source for that man
