Problem 10QQ

Choose the best answer to each of the following. Explain your reasoning with one or more complete sentence

The major evidence for the idea that the expansion of the universe is accelerating comes from observations of (a) white dwarf supernovae. (b) the orbital speeds of stars within galaxies. (c) the motions of galaxies within galaxy clusters.

Step-by-Step Solution:

Step 1 of 2</p>

Since we know that the universe is expanding and our galaxy is moving away from other galaxies at increasing speed hence the expansion of the universe is accelerating comes from observations of white dwarf supernovae.

The orbital speeds of stars within galaxies do not change from the center of the galaxy. Hence it does not expand.

The motion of galaxies within the cluster is generally observed by Zwicky’s he said that it moves in an irregular form.
