− | + | This comic appears to be a {{w|Venn diagram}} depicting {{w|Earth}} and {{w|Venus}}. A Venn diagram would be used to compare the two and show certain traits that each has distinct, as well as, in the middle area, traits shared by both planets. However, on reading the text, it becomes clear that the "diagram" actually depicts Earth ''colliding'' with Venus, as each of the circles in the diagram could be construed as the planets. This justifies the central label of "shockwaves and production of impact ejecta", as this is exactly what would be present in such a collision at the area of contact.{{Citation needed}} The sizes of the two circles also match the relative sizes of the two planets, since Earth and Venus have about the same size. | |

− | + | The title text continues the comparison by pointing out that {{w|Mars}} is part of the diagram, but presumably orbiting safely (just that we can't see it). Therefore, this makes the overall system an {{w|Euler diagram}} rather than a Venn one, as every circle in any way represented in a Venn diagram must intersect. xkcd has referenced the difference between Euler and Venn diagrams [[2721: Euler Diagrams|before]]. The title text also calls it an "Euler apocalypse" to emphasize that it represents an important event rather than the sets of traits that either type of diagram normally represents. Going off of this, a "Venn apocalypse" would consist of every (present) spherical body in the universe colliding simultaneously. | |
