The image presented here is a play on the concept of a lunar eclipse, integrating the controversial and widely debunked theory of a flat Earth. It depicts the full moon, highly detailed and filling the frame, with a peculiar, horizontal bar of shadow across its center. Above and below this shadowed stripe, the text "FLAT EARTH" and "ECLIPSE" are respectively captioned, implying that the shadow is caused by a flat Earth intervening between the sun and the moon.
What makes the image humorous to some is the intentional absurdity and irony. A lunar eclipse traditionally occurs when the Earth, round in shape, casts a shadow on the moon's surface, creating a curved edge to the shadow. This image, however, shows a straight-lined, flat shadow across the moon which contradicts the well-understood, scientifically accepted spherical nature of the Earth.
The juxtaposition of a scientifically inaccurate scenario with the familiar imagery of a lunar eclipse creates a visual pun. It plays on the expectation of the viewer who understands how a lunar eclipse should look and then subverts it with an impossible flat shadow. This tickles the funny bone through the sheer ridiculousness of the image's premise when compared to the established knowledge of celestial mechanics.
Another layer of humor derives from the ongoing discourse around the flat Earth theory. The image mocks the flat Earth concept by taking it to its literal visual conclusion, posing a humorous "what if" scenario. In this way, it serves both as a joke and a light-hearted critique of the flat Earth ideology.
The humor also arises from the shared social context surrounding the flat Earth theory. It's a topic that frequently spawns memes and jests due to its fringe nature and the passionate discourse it generates. Those viewing the image are likely in on the joke, understanding that the notion of a flat Earth is at odds with basic astronomy and physics, making this erroneous eclipse depiction an inside joke of sorts.
Lastly, the image could be seen as funny simply because it plays with an established convention – that of space photography. The official and serious tone typically associated with images from space is turned on its head here. Instead, the image brings levity and satire to a field of study that's usually quite serious, inviting viewers to laugh at the absurdity presented before them. FLAT EARTH ECLIPSE
