Cosmology is a branch of metaphysics that deals with the nature of the universe, a theory or doctrine describing the natural order of the universe.
The basic definition of Cosmology is the science of the origin and development of the universe.
In modern astronomy, the Big Bang theory is the dominant postulation..
Cosmology studies how the history of the universe led to the stars, galaxies, and other features we can observe today.
Cosmology is the study of the origin, development, structure, history, and future of the entire universe..
According to NASA, the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole." Cosmologists puzzle over exotic concepts like string theory, dark matter and dark energy and whether there is one universe or many (sometimes called the multiverse)..
Cosmology deals with the physical situation that is the context in the large for human existence: the universe has such a nature that our life is possible.
This means that although it is a physical science, it is of particular importance in terms of its implications for human life..
