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?
More distant raisins would be moving away from you faster.
All raisins would be moving away from you at the same speed, without any dependence
As you can see in the graph it is irrelevant if they are on one side or another of the cake since you would see everyone moving away from you at the same speed since the cake must undoubtedly expand to establish a distance of 3cm between the raisins .
Note: It should be understood that the dough should be uniform and the ideal cooking conditions for a standard cake
More distant raisin would be moving away from you faster
As the cake expands, it expands around the center causing other raisins to move away from the center with the extreme raisins moving faster away from the observation.
