  1. Astronomy 123 Cosmology and the Origin of Life

  2. Cosmology • Cosmology is the empirical study of the organization, structure and evolution of the Universe • At any given time we always think our Cosmology is correct: • Ancient: Earth is at center of Universe • Current: Dark Matter and Dark Energy • At any given time our Cosmological models are always incomplete

  3. A Cosmological Model Models are made from observations and are empirical. This necessarily means that models are limited because the range of accessible observations is limited. Good models make predictions that can be tested. This is the "acid" test of any model and is the root of the scientific method . Without this test, models can simply be arbitrary
