Experimental tests of a new theory of gravitation

Canadian Journal of Physics, 1981
The predictions for the perihelion shift, the deflection of light, and the delay time of a light ray are calculated in the nonsymmetric theory of gravitation. An upper bound for the parameter l (that occurs as a constant of integration in the static, spherically symmetric solution of the field equations) is obtained for the sun for the experimental ...

Experimental Tests of the Black Hole Entropy Prediction of the Order Parameter Spacetime Theory — Gravitational Wave and Black Hole Shadow Observations

The Order Parameter Spacetime Theory provides an exclusive explanation for the microscopic origin of black hole entropy: S = ∫Ξ dA, the area integral of information dissipation at the horizon. Starting from the information-Einstein equation, the theory rigorously derives the Bekenstein-Hawking entropy formula S = A/4 at a type-B traversable singularity.
