1158: Rubber Sheet
Title text: It IS about physics. It ALL is.
This comic refers to a common analogy used to explain how mass distorts space-time — a bowling ball resting on a sheet of rubber distorts the sheet due to its weight. The system has some qualitative features in common with gravity; it's often misused to show that "mass warps spacetime" (895: Teaching Physics).
The next part of the original analogy explains a black hole: the slope of the sheet becomes so deep that you can't climb out from the bottom any more, similar to a black hole, which even light can't escape from. However, the comic subverts the analogy, and the sheet becomes a trampoline instead.
Reading onwards, it is seems that Beret Guy is just messing about with the scenario.
The line "Imagining is fun!" is also a homage to Richard P. Feynman's "Fun to Imagine" Series of Interviews.
The title text also states that the rubber sheet, broken rope and our whole life is all about physics (see also 435: Purity).
- [Beret guy is standing on a giant bowling ball on a rubber sheet. Megan is watching.]
- Beret Guy: Imagine a giant bowling ball on a rubber sheet.
- Beret Guy: The ball's weight makes a dent in the sheet.
- [A rope is pulling the ball down into the sheet.]
- Beret Guy: Now imagine a rope that pulls the ball down even further.
- Beret Guy: ...Annnnd...
- [Rope lets go. Ball is catapulted with Beret Guy on it.]
- Beret Guy: Wheee
- [Beret guy and ball are falling back down.]
- Megan: ...Oh. I thought this was about physics.
- Beret Guy: Imagining is fun!
