    Michael, that example of a "pre-renaissance" painting that you used does not prove what you think it does. Byzantine iconography is drawn using a reverse perspective for theological reasons, in fact, modern day Byzantine iconography is still drawn this way. You can read more about it here: books.google.com/books?id=1ksDKW9PiI4C&pg=PA54#v=onepage&q&f=false

    When I was in the car with my mom driving. I asked her why the moon was moving everywhere and I asked why it kept switching directions. Of course she told me it wasn't. I always wondered why it seemed the moon was following us in the car.

    Worst Vsauce video yet. Starts by describing an illusion that I've never seen or heard of (the moon's angle of illumination has always looked just fine to me) then goes into tons of needless explanation about perspective, foreshortening, and parallax (common knowledge) and never gets back to the moon thing at all, ending up on perspective in art history. What a load of clickbait.

    Basically it's because people are assuming the sun and moon are on the same plane like they're right next to each other, when the sun is like 93 million miles away, and the moon is only about 240,000 miles away on average. Your perception of perspective is messed up, unless you really think about it.

    Vsauce, Michael here, you are as clear as mud. I know you're a paid actor and all, but if what you are saying is true, then not only is the moon terminator line an illusion for me here in Illinois, it has to be an illusion for the other 7 billion inhabitants here on earth. Really? The questions begs, how was this determined? By what mathematician? And from what angle was this realized? From outer space? Are we to believe that illusion is the basis for our perception? This is pure skullduggery.

    tldr: hi's wrong about the icon thing.
    Icons like the one in his example don't have the same perspective as those renessance paintings do. They don't even try to look that way, and it's much more about theology than knowledge or skills of realistic painting. It's based on the prohibition of statues of gods in judaism, which partly spred to christinianity. Orthodox church interprets that prohibition by following a rule in the holy pictures, which doesn't allow "normal" perspective because that would be too close to statues that are three dimentional. The perspective is instead opposite to the western, and seems to come towards the observer, as if the picture takes the one looking at it inside of the scene. They are windows to Heaven after all.

      +Adûnâi Not race nor IQ, more like ideaology and behavior in the age of reasoning and still people hold on to irrational beliefs. Even when it goes against their own interest. It's self defeating in my opinion but I don't know theirs and IQ wouldn't provide the answer. There's alot of intelligent people, regular people with good jobs and families, they pay their bills, educated, but a different side will show when it gets personal and they become psychotic. I know a 10th grade math teacher who swears Obamas the anti-christ. Shit like that. You know.
