Møller was the director of the European Organization for Nuclear Research (CERN)'s Theoretical Study Group between 1954 and 1957 and later a member of the same organization's Scientific Policy Committee (1959-1972).[4]
Møller tetrad theory of gravitation
In 1961, Møller[5][6] showed that a tetrad description of gravitational fields allows a more rational treatment of the energy–momentum complex than in a theory based on the metric tensor alone. The advantage of using tetrads as gravitational variables was connected with the fact that this allowed to construct expressions for the energy-momentum complex which had more satisfactory transformation properties than in a purely metric formulation.
Subrahmanyan Chandrasekhar came up with his theory of the Chandrasekhar limit for the maximum stable mass of a star, in 1930. This calculation was in opposition to Sir Arthur Eddington theories about stars. Eddington mocked Chandrasekhar various times and frequently campaigned against Chandrasekhar during conferences.[7]
In 1935, Møller was the first to write a paper in collaboration with Chandrasekhar to criticise Eddington's theory. They wrote "we are quite unable to follow [Eddington's] arguments." They also proceeded to refute Eddington's follow up paper showing contradictions in his theory.[7]
