    Physical cosmology is the branch of physics and astrophysics that deals with the study of the physical origins and evolution of the universe. It also includes the study of the nature of the universe on a large scale. In its earliest form, it was what is now known as "celestial mechanics," the study of the heavens.

  3. Cosmology relies on extrapolating local physical laws to hold universally. These extrapolations make it possible to infer, from observations of standard candles such as Type Ia supernovae, 1 the startling conclusion that the universe includes a vast amount of dark matter and dark energy.

  4. The assumptions of homogeneity and isotropy are so fundamental that we call this the cosmological principle. It states that an observer in another galaxy would see the universe to have the same properties as we do. Note that there is a difference between a homogeneous universe and an isotropic one.

  5. Nov 22, 2024 · Cosmology, the field of study that brings together the natural sciences, particularly astronomy and physics, in a joint effort to understand the physical universe as a unified whole. When the universe is viewed in the large, a dramatic new feature, not present on small scales, emerges—the cosmological expansion.

  6. Cosmology explores the origin, evolution, and eventual fate of the universe, intertwining physics and astronomy to understand cosmic phenomena. This field examines the large-scale structure of the cosmos, relying on theories such as the Big Bang and dark matter.

  8. Research in cosmology involves astronomy, but also gravitational physics, particle physics, and challenging questions about the interpretation of phenomena we can’t see directly — such as the possible existence of something before the Big Bang.
