Cosmology

Cosmology is the scientific study of the large-scale structure, origin, evolution, and ultimate fate of the universe. It seeks to understand the fundamental nature of the cosmos, including the distribution of galaxies, dark matter, dark energy, and the overall geometry of space-time. Cosmologists explore the early moments of the universe, moments after the Big Bang, and employ various observational tools, such as telescopes and satellites, to gather data that informs our understanding of cosmic evolution.

Key concepts in cosmology include the expansion of the universe, cosmic microwave background radiation, and the formation of galaxies and large-scale structures. It is a field that intersects with physics, astronomy, and astrophysics, providing insights into the vast and intricate tapestry of the cosmos.
