This website presents basic information and concepts about Cosmology and our current best understanding of the Universe. Cosmology is the scientific study of the large scale properties of the Universe as a whole. It endeavors to use the scientific method to understand the origin, evolution and ultimate fate of the entire Universe. Like any field of science, cosmology involves the formation of theories or hypotheses about the universe which make specific predictions for phenomena that can be tested with observations. Depending on the outcome of the observations, the theories will need to be abandoned, revised or extended to accommodate the data. Includes sections on: Big Bang Theory, Big Bang Tests, Beyond the Big Bang, and Our Universe.
