Observational Cosmology

This is a subfield that focuses on the collection and interpretation of observational data about the universe to test and refine cosmological models and theories.

What is observational cosmology?

"Observational cosmology is the study of the structure, the evolution, and the origin of the universe through observation."

What specific methods are used in observational cosmology?

"...using instruments such as telescopes and cosmic ray detectors."

How is the structure of the universe studied in observational cosmology?

"...the study of the structure, the evolution, and the origin of the universe..."

How is the evolution of the universe studied in observational cosmology?

"...the study of the structure, the evolution, and the origin of the universe..."

How is the origin of the universe studied in observational cosmology?
