Imagine that we put a raisin cake into the oven, with each raisin separated from the others by 1 cm. an hour later, we take it out and the distances between raisins are 3 cm. if you lived in one of the raisins and watched the other raisins as the cake expanded, which of the following would you conclude?
- all raisins would be moving away from you at the same speed.
- it depends: if you lived in a raisin near the left side of the cake, you'd see other raisins moving away from you, but they'd be coming toward you if you lived in a raisin near the right side of the cake.
- more distant raisins would be moving away from you faster.
- more distant raisins would be moving away from you more slowly.
