"Gravitation and Cosmology"

"Gravitation and Cosmology" explores how gravity—the force that attracts objects with mass—shapes the universe. It explains how planets orbit stars, how galaxies form and evolve, and how the universe itself expands over time. The field combines Einstein’s theory of general relativity with observations of cosmic phenomena, helping us understand the large-scale structure of the cosmos, the origins of the universe, and its ultimate fate. Essentially, it studies the fundamental gravitational interactions that govern everything from everyday objects to the entire universe’s behavior.
