Cosmology is the study of planets, stars, galaxies, and universes and gives insights into how the universe works. Cosmologists discover laws of the cosmos, not create them. They communicate the cause and effects of each law and explain them in ways the average intelligent person can understand. They base their insights on questions, doubts, experimentation, exploration, testing and formulating hypotheses that others can challenge and change as new evidence emerges.
