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.
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.
- [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!
