Question

A friend uses an analogy of raisins in rising bread dough to describe galaxies in the expanding universe. Is your friend’s analogy strong? Explain.

Answer 1

The analogy of raisins in rising bread dough is a strong one to describe galaxies in the expanding universe.

Step-by-step explanation:

The analogy of raisins in rising bread dough to describe galaxies in the expanding universe is a strong analogy because it helps to illustrate the concept of galaxies moving away from each other as the universe expands. In both cases, the individual components (raisins in dough, galaxies in the universe) do not themselves grow or change in size, but they move farther apart due to the stretching of the medium (dough, space). Just like the raisins in the bread dough, as the universe expands, galaxies get farther away from each other without changing in size.

Answer 2

Not a strong analogy. Galaxies formed through lots of cosmic “dust” coming together because of gravity. Bread rises due to an increase in heat, causing a chemical reaction. This is not really anything like the formation of galaxies.
