Cosmology (philosophy)

Cosmology is a branch of philosophy that studies the origins and structures of the universe. It looks at how the universe came to be, what it is made of, and how it works. In other words, cosmology is the study of the big picture of our universe. Cosmologists ask the big questions about the universe - how it started, how it works, and how it might end. To answer these questions, cosmologists use theories and mathematical models. These models take into account things like the basic laws of physics, the origin of matter and energy, and the history of the universe. Cosmology is a very complex subject, but understanding it can help us to understand more about the world we live in.
