Branch of philosophy – philosophy is the study of general and fundamental problems, such as those connected with existence, knowledge, values, reason, mind, and language. Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument. Academic discipline – branch of knowledge that is taught and researched at the college or university level. Disciplines are defined (in part), and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties to which their practitioners belong.

Branches of metaphysics

Physical cosmology – study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its formation, evolution, and ultimate fate. Big Bang cosmology (standard) – cosmology based on the Big Bang model of the universe. The Big Bang is a theoretical explosion from which all matter in the universe is alleged to have originated approximately 13.799 ± 0.021 billion years ago. Non-standard cosmology – any physical cosmological model of the universe that has been, or still is, proposed as an alternative to the Big Bang model of standard physical cosmology. Plasma cosmology – a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas, rather than gravity, play the dominant roles in the formation, development, and evolution of astronomical bodies and large-scale structures in the universe. Religious cosmology – body of beliefs based on the historical, mythological, religious, and esoteric literature and traditions of creation and eschatology. Abrahamic cosmology – The cosmology of all Abrahamic religions, including the Biblical Cosmology of Judaism and Christianity, and Islamic Cosmology. Based on the ancient writings from each of these respective religions, it entails a conception of the Cosmos as an organised, structured entity, including its origin, order, meaning and destiny. Buddhist cosmology – description of the shape and evolution of the Universe according to the Buddhist scriptures and commentaries. Hindu cosmology – In Hindu cosmology the universe is cyclically created and destroyed. The Hindu literature, such as Vedas, and Puranas, cite the creation of the universe. They describe the aspects of evolution, astronomy, etc. Jain cosmology – description of the shape and functioning of the physical and metaphysical Universe (loka) and its constituents (such as living beings, matter, space, time etc.) according to Jainism, which includes the canonical Jain texts, commentaries and the writings of the Jain philosopher-monks. Taoist cosmology – cosmology based on the School of Yin Yang which was headed by Zou Yan (305 BC – 240 BC). The school's tenets harmonized the concepts of the Wu Xing (Five Phases) and yin and yang. In this spirit, the universe is seen as being in a constant process of re-creating itself, as everything that exists is a mere aspect of qi, which, "condens
