We provide you all the answers keys for all the big bang theory hubbles law gizmo questions. The universe is expanding and galaxies are moving away from each other. Record: Repeat the procedure to measure the redshift of each star. A similar effect occurs if a star or galaxy is moving relative to Earth. Based on the graph, what is the approximate mean luminosity of a Cepheid. This indicates that the universe was initially hot and has cool down the past 14 billions years. A. the study of the origin, structure, and future of the universe, many current theories of the universe began with observations made ______ years ago. absolute brightness, absorption spectrum, apparent brightness, Big Bang theory. decreases again.
