Christian Møller (22 December 1904, Hundslev, Als – 14 January 1980, Ordrup) was a Danish chemist and physicist who made fundamental contributions to the theory of relativity, theory of gravitation and quantum chemistry.
[4] 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.
[7] In 1935, Møller was the first to write a paper in collaboration with Chandrasekhar to criticise Eddington's theory.
They also proceeded to refute Eddington's follow up paper showing contradictions in his theory.
