Raisin Bread Galaxies at Bobby Hilson blog

Raisin Bread Galaxies. Each raisin would be stuck in a particular position within the loaf of bread dough. Before baking, the raisins are scattered around in the dough. Imagine making a loaf of raisin bread (figure 13.7). One final analogy may help you visualize why we say the universe expands (space stretches) but galaxies do not. When the loaf is left to rise, the raisins get further and further apart because there is more space between them. It is important to remember that the raisins are not flying apart on their own due to some sort of explosion, they are simply being carried along. The raisins in the dough are like the dots on the rubber band or galaxies in the universe. All galaxies will see other galaxies moving away from them in an expanding universe unless the other galaxies are part of the same. One way to think about the expanding universe is to imagine that the universe is a loaf of raisin bread. The galaxies are the raisins, and the dough is the space between galaxies or large structures. If every portion of the bread expands by the same amount in a given interval of time, then the raisins would recede from each other with exactly a hubble type expansion law. As the dough expands, the separation between the raisins increases, just like the separation between galaxies in our universe. Beginning in 1912, and making heroic efforts over a period of about 20 years, slipher managed to photograph the spectra of more than 40 of the spiral nebulae (which would all. The expanding raisin bread model at left illustrates why this proportion law is important.
