89: Gravitational Mass
| Gravitational Mass |
 Title text: She's so fat the attraction goes up as the CUBE of the distance instead of the square |
[edit] Explanation
A well known joke format goes thusly: "Yo' momma's so fat, when she X, she Y." For example: "Yo' momma's so fat, when she sits around the house, she sits around the house! Variations play with the format, for example: "Yo' momma's so fat, she fell in the grand Canyon and got stuck!"
In this comic, Black Hat launches into a long description about the relativity of gravity and inertia that presumably will eventually lead to a Yo' Momma joke, but then gets bored or loses momentum and cuts to the chase.
The title text is a play on the law of gravitational attraction, which diminishes as the square of the distance. So if the distance between two objects doubles, the attraction is reduced to a quarter. And if the distance is halved, the attraction quadruples. Black hat is saying that the attraction goes up as the cube, so if the distance is halved, the attraction increases eight-fold. In other words, your momma is so fat, she can warp space-time.
[edit] Transcript
- Black Hat: Gravitational mass is identical to inertial mass. That is, the amount of inertia something has and the amount of gravity it has are effectively the same. What's interesting is that there doesn't seem to be any reason this should be true. One could imagine an extremely large object with lots of resistance to force and no gravity (or vice versa), but this is never observed.
- Black Hat: You know what? I'm just gonna skip the rest of the buildup and say it: Yo mama's fat.
