Cosmology

Cosmology is a branch of physics and metaphysics that deals with the nature of the universe.

• In astronomy, cosmology is concerned with the study of the chronology of the universe.
• Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology.

Types of Cosmology

Physical cosmology

The study of the observable universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas.

A sub-branch of astronomy, it concerns the universe as a whole.

This branch is investigated by different types of scientists, including astronomers and physicists, as well as philosophers.
Due to this overlap, theories may include both scientific and non-scientific ideas, and may depend on things that cannot be tested.

Quantum cosmology

The attempt in theoretical physics to develop a quantum theory of the universe.

This approach attempts to answer questions of classical physical cosmology, particularly those related to the first phases of the universe.
To bridge the gap between classic cosmology and physical cosmology, theories are needed to integrate the different aspects of cosmology together.

In quantum cosmology, the universe is treated as a wave function instead of classical spacetime.[5]

Fun fact: This branch of cosmology is studied by Vulcan children in the 23rd century.

Theoretical cosmology

A branch of astronomy that theorizes the structure, origins, evolution, and space-time relationships of the universe.

One who studies the metaphysics of the universe in the field of cosmology, no matter the sub-branch, are all known as cosmologists.
