The Einstein–Cartan–Evans theory is a unified theory
Unified field theory
In physics, a unified field theory, occasionally referred to as a uniform field theory, is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a single field. There is no accepted unified field theory, and thus...

Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

General relativity
General relativity or the general theory of relativity is the geometric theory of gravitation published by Albert Einstein in 1916. It is the current description of gravitation in modern physics...

Quantum mechanics
Quantum mechanics, also known as quantum physics or quantum theory, is a branch of physics providing a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It departs from classical mechanics primarily at the atomic and subatomic...

Electromagnetism is one of the four fundamental interactions in nature. The other three are the strong interaction, the weak interaction and gravitation...

. The proposed theory was largely published in the journal Foundations of Physics Letters between 2003 and 2005. Several of Evans's central claims were later shown to be mathematically incorrect and, in 2008, the editor of Foundations of Physics

published an editorial note effectively retracting the journal's support for the theory.

Scope of theory

In the synopsis of his first book, Evans writes:
Earlier versions of the theory were called "O(3) dynamics".

The theory has been used to justify the motionless electromagnetic generator, a perpetual motion machine.

Criticisms

Evans's claims are not accepted by the mainstream physics community. In an editorial note in Foundations of Physics

the Nobel laureate Gerard 't Hooft discussed the "revolutionary paradigm switch in theoretical physics" promised by ECE theory. He concluded that activities in the subject "have remained limited to personal web pages and are absent from the standard electronic archives, while no reference to ECE theory can be spotted in any of the peer reviewed scientific journals".

Several of the published contributions in this theory have been shown to be mathematically incorrect. In response to these demonstrations, 't Hooft's editorial note concludes, "Taking into account the findings of Bruhn, Hehl and Obukhhov, the discussion of ECE theory in the journal Foundations of Physics will be concluded herewith unless very good arguments are presented to resume the matter."
