Electromagnetic tensor is a 2-form derived from the exterior derivative of a 1-form, similarly Gravitomagnetic tensor [1] can be derived from the exterior derivative of the Energy momentum 1-form and we obtain the similar Maxwell`s equations.

Gravitomagnetic tensor [1] generates the extra force needed to explain the anomalous behavior of pendulums observed during a solar eclipse [2] and dark matter effect.

Solving the Schrodinger equation with the gravitational potential added to the electrical potential we are able to get the gravitomagnetic photon frequency.

Equating the Schrodinger energy value to the total energy in several gravitational systems we get the value of Planck constant in these systems.

For the hydrogen atom, Z = 1, the first term in equation (21) is -13.6 eV, the third term is due to the gravitational interaction and the second term is due to the fact that the electron is closer to the nucleus than it would be without the electromagnetic interaction.

Gravitomagnetic tensor has been derived from the Energy-momentum and we have obtained the similar Maxwell`s equations, when a charged particle is moving it generates a magnetic field that interacts with charged particles in motion, similarly when a particle is moving it generates a gravitational magnetic field that interacts with other particles in motion.

Gravitomagnetic photon frequency is obtained by solving the Schrodinger equation including the gravitational potential, the detection of this photon leads to a new Astronomy.

The variation in Planck constant is obtained by solving the Schrodinger equation in several gravitational systems, it is not a constant anymore, it depends on the masses and the distance.

Galaxies in our universe are rotating with such speed that the gravity generated by their observable matter could not possibly hold them together. Gravitomagnetic tensor and the interaction due to the torsion tensor explain dark matter, the shape of galaxies and their distribution in the universe.

Gravitational magnetic force explains other anomalies such as that of the Pioneer spacecraft and its acceleration when moving away from the Sun.
