Teoriamallinnointia, also known as "theory of everything" or "theory of all", is a hypothetical framework in theoretical physics that fully explains and links together all physical aspects of the universe. It is a set of principles that can describe all physical phenomena, from the smallest particles to the largest structures in the cosmos. The term was popularized by physicist Edward Witten in the 1980s.

The search for a theory of everything has been a major goal of modern physics. It aims to unify the four fundamental forces of nature: gravitation, electromagnetism, and the strong and weak nuclear forces. Currently, the most successful theories in physics are the Standard Model of particle physics, which describes three of these forces, and general relativity, which describes gravitation. However, these theories are not compatible with each other, and they do not provide a complete description of the universe.

Several candidates for a theory of everything have been proposed, including string theory, loop quantum gravity, and twistor theory. Each of these theories attempts to provide a consistent mathematical framework that can describe all physical phenomena. However, none of these theories has been experimentally confirmed, and the search for a theory of everything remains an active area of research in theoretical physics.

The concept of a theory of everything is closely related to the idea of a unified field theory, which seeks to describe all fundamental forces and particles in a single, consistent framework. However, a theory of everything goes beyond a unified field theory by also providing a description of the universe's initial conditions and its ultimate fate.

Despite the challenges and uncertainties involved in the search for a theory of everything, it remains a central goal of modern physics. A successful theory of everything would provide a deep understanding of the fundamental nature of the universe and could have profound implications for our understanding of the cosmos.
