Physical Cosmology
Definition of Physical Cosmology as it relates to Science, Astronomy, Astrophysics
Physical cosmology is the study of the largest-scale structures and dynamics of the universe and its observable phenomena, including the nature of dark matter and dark energy, the formation and evolution of galaxies, and the origins of cosmic structure. It lies at the intersection of astronomy, astrophysics, and particle physics, and seeks to understand the fundamental laws that govern the behavior of matter and energy on cosmological scales. As a subfield of astrophysics within the broader context of science and astronomy, physical cosmology builds upon observational data and theoretical models to explore the history, composition, and fate of the universe.
