Document Summary
Astronomy is defined as the study of the objects that lie beyond our planet earth and the processes by which these objects interact with one another. Science is a progress report: one that changes constantly as new techniques and instruments allow us to probe the universe more deeply the universe made the carbon, the calcium, and the oxygen. The ultimate judge in science is always what nature itself reveals based on observations, experiments, models, and testing. Science is not merely a body of knowledge, but a method by which we attempt to understand nature and how it behaves. A new model, with the sun at the center, fit the experimental evidence better. Dark energy make up the bulk of the universe. New scientists know that one of the best ways to advance their careers is to find a weakness in our current understanding of something and to correct it with a new or modified hypothesis.
