    What's going on here? Really? Look, Michael either doesn't know or doesn't care about the real nature of the Moon. But this isn't the place for truth. That's not what this channel, this pop-sci community is about. It's its own culture. At this point, I'm more inclined to believe that the Moon is analogous to Eve in the sense that this 'lesser light' (Gen 1:16) has somehow been violated: And this is the trauma we still somehow sense today. The traumatized girl as depicted in Carrie, Firestarter, Stranger Things, X-Men: Dark Phoenix, etc. This recurrent theme of the manipulated violated feminine, damsel in distress, that in turn is turning those receptive to its dark lunar influence into lunatics. It's really sick stuff. Freud was right. It's all sexual.

    that door illustration is so stupid idiot the door did shrink it was not an illusion. From your view point and if i measured it the door would be thinner untell it is shut that computer thing is stupid as well i can not get any closer or further away from the moon so it will always be as it is besides if that affect were true the moon would loose its sharp as your face did ,hey dumb ass take a straight ruler and put it close to your eyes then line it up with the ceiling wow no illusion there your camera trick is just a trick any camera will do. Put the ruler in-front of the camera and follow the ruler no curve there either,

    I can get relatively close to the moon with my 63x zoom camera. If the moon was 240.000 miles away, such a small zoom wouldnt make any difference to the perceived size. Id need something much more powerful. Therefore, the moon has to be smaller and closer.

    • Lozip
      Lozip 8 days ago

      That happens because in a zoom all angular size stays the same and the image is simply enlarged. Movement on the other hand does effect angular size. Hope this helps!

    6:49 I remember we had the term "Parallax" in our class 10 Physics book but no one in the class clearly understood it neither did the teacher took the pains to makes us understand the term....everyone just mugged it up but this video explains this term so clearly... .Thus we need more of this interesting way of teaching rather than our old and faulty education system....!

    I think that the art part is misguided. Art can be seen as an independent phenomenon which developed by itself via small improvements at hands of either excentric individuals, or fortituous mistakes. The interest of artists, seems to me, WAS to paint accurately, but they didnt have the tools of perspective at hand in order to do so. Moreover, intelligence when it comes to pictorial ability has increased significantly since the early middle ages.

    This has always bugged me. I knew it must be something to do with perspective and vanishing points but that didn't help me 'unsee' what I thought I was seeing, i.e. the line of sight from the sun was not perpendicular to the moon's terminator. The panning camera demo finally nailed it for me. I missed this video when i was first available, somehow, but you mentioned it during your hike with Kevin Nealon under the Hollywood sign. Many thanks! Love the way you can explain the same thing in a dozen different ways - one of them will stick :)
