ASTRONOMY is the study of all matter and energy in the Universe. Astronomy impacts our history, psychology, beliefs, feelings, and culture.
Earth –> Solar System –> Milky Way Galaxy –> Galaxies –> Super Galaxies –> Universe
- Time and space born 14 billion years ago in the “Big Bang”
- The Universe is expanding and cooling from primordial soup
- Early on, the Universe was so hot that even atoms could not exist; a sea of elementary particles
- Earth is a roughly spherical planet that orbits around a typical star in the middle outskirts of a typical galaxy among billions of galaxies
Prehistory: the “WHAT” through observations of the rhythms and cycles of nature and the sky
Early History: the “HOW” through plausible explanations to explain these phenomena with systematic observations and philosophical and aesthetic perspectives
Modern History: the “WHY” through scientific investigations, experiments, and systematic measurements
