Respuesta :
One famous analogy to explain the expanding universe is imagining the universe like a loaf of raisin bread dough. As the bread rises and expands, the raisins move farther away from each other, but they are still stuck in the dough.
The universe is like raising bread dough because the universe is expanding day by day, and the raisins are the galaxies, which are going far away with the expansion.
What is the universe?
The universe is the space and time when all the planets, galaxies, stars, and all other energies are present. The universe also includes time and energies.
The comparison of the universe to the bread dough is as the bread dough expands, the universe and the raisins are like galaxies that go far away as the expansion of bread and universe.
Thus, because the universe is expanding every day and the galaxies are the raisins that are traveling far away with the expansion, the universe is like raising bread dough.
