− | ''' | + | A Venn diagram compares two entities and shows, in the middle area, traits or properties common to both, and in the non-overlapping regions, those that are unique to the respective entities. This diagram is simultaneously both a '''{{w|Venn diagram}}''' and a '''proximity illustration'''. |
+ | * As a '''proximity illustration''', it depicts {{w|Earth}} and {{w|Venus}} smashing into each other, resulting in "shockwaves and production of impact ejecta" occuring 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." | ||
− | + | Shockwaves refer to intense, high-pressure waves that propagate through the materials of both planets at speeds exceeding the sound speed, caused by the immense force of the impact. | |
− | + | Impact ejecta refers to 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 notes that {{w|Mars}} is still orbiting by itself, though presumably out of the frame of the "diagram", since we can't see it. Therefore, this actually 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 abstract analysis of properties that either type of diagram normally represents. Going off of this, a "{{w|Big Crunch|Venn apocalypse}}" would consist of every (present) spherical body in the universe colliding simultaneously. This would be dangerous.{{citation needed}} | |
