In science, astronomers must analyze many observations and separate out those that provide evidence in support a specific theory. To reinforce the credibility of a theory, astronomers must look for multiple, independent pieces of evidence. Consider the following example: Astronomers believe that every bright galaxy harbors a supermassive black hole at its center. Sort the following observations according to whether they support or do not support this theory.
-Stellar black holes in interacting binary systems-Fast motions of closely orbiting material in galactic nuclei-Exceptionally bright galactic nuclei-Spiral arms in the outer disks of galaxies-Globular clusters in the outer galactic haloes
-Powerful jets of high-speed material
