− | * As a '''proximity illustration''', it depicts Earth and Venus smashing into each other, resulting in "shockwaves and production of impact ejecta" occurring where they collide. The relative circle sizes are accurate; the circumference of Venus is 5% smaller than Earth's. | + | |

+ | * As a '''Venn diagram''', it accurately shows what traits the planets have in common in the event of a collision: "shockwaves and production of impact ejecta," and that the area of overlap is now an intermingled combination of Earth and Venus. | ||
'''Shockwaves''' are intense, high-pressure waves caused by the immense force of the impact, that propagate through the materials of both planets faster than the speed of sound. | '''Shockwaves''' are intense, high-pressure waves caused by the immense force of the impact, that propagate through the materials of both planets faster than the speed of sound. | ||
− | '''Impact ejecta''' | + | '''Impact ejecta''' is the material expelled from the impact site, consisting of molten rock, vaporized material, and solid debris, flung out at high velocities due to the energy released by the collision. |

− | + | The '''title text''' is [[2721: Euler Diagrams|another xkcd joke]] about the difference between a [[:Category:Venn diagrams|Venn]] diagram and a [[:Category:Euler diagrams|Euler]] diagram, which is like a Venn diagram except that it's acceptable to have circles (or other shapes) that do not intersect if there are no common elements between those sets. The observation that {{w|Mars}} is still orbiting by itself makes Mars an additional set (out of the frame of the diagram), in addition to - but not intersecting with - Earth and Venus, making this technically a {{w|Euler diagram}}. Therefore if the Earth-Venus collision is a "Venn apocalypse," the inclusion of Mars as a non-intersecting entity makes this technically a "Euler apocalypse." | |
− | + | As a thought experiment, if you expand the diagram infinitely, a "{{w|Big Crunch|Venn apocalypse}}" would consist of every body in the universe being in the process of colliding, simultaneously. This would be dangerous.{{Citation needed}} | |
