What is the primary focus of cosmology?

The primary focus of cosmology is the study of the properties, structure, and evolution of the universe. This field encompasses the overall understanding of the universe's origin, its large-scale structures, such as galaxies and galaxy clusters, and its dynamic processes, including expansion and cosmic background radiation. Cosmologists investigate fundamental questions about the universe's beginnings, its current state, and its ultimate fate. This makes it distinct from other branches of astronomy that may focus on more localized phenomena, such as individual stars or planetary systems. The breadth of cosmology allows it to address profound questions regarding the nature of time, space, and the fundamental forces that govern everything we observe in the cosmos.
