2. What evidence suggests that the Milky Way contains dark matter? Group of answer choices We observe stars and gas clouds far from the galactic center orbiting the galaxy at higher speeds than we would expect without dark matter. When we look at the galactic center, we are able to observe a large black hole that is composed of dark matter. We see many lanes of dark material blocking out the light of stars behind them along the band of the Milky Way. We see many dark voids between the stars in the halo of the Milky Way. When we observe in different wavelengths, such as infrared or radio, we see objects that don't appear in visible-light observations. 3. Which of the following best describes how galaxies are distributed on large scales in the universe? Group of answer choices Galaxies are randomly distributed throughout space. Galaxies are distributed in large, elongated chains radiating outward from a common center. Galaxies are distributed in a series of concentric spherical shells around a common center. Galaxies appear to be distributed in chains and sheets that surround great voids. Galaxies are uniformly distributed throughout space.
