The 5D fully-covariant theory of gravitation and its astrophysical applications.
In the case of continuously distributed substance throughout the entire volume of space in the gravitational and electromagnetic fields, we shall use the Lagrangian function L, which in the covariant theory of gravitation (CTG) has the form [3]:
Moreover it is inconceivable that there could be any structure preservation between a mechanical theory of gravitation, like Newtonian physics, and a geometrical theory of gravitation, like Einstein's general relativity theory, where no forces and potentials can exist.
As before, there are two fundamental conflicting theories, namely: Newton's theory of gravitation ([T.
Fortunately, Einstein appears to have formulated a consistent theory of gravitation in which anomalies are avoided but all else is permitted.
But my point is that gravitational mass may not be equal to inertial mass due to some quantum effects in General Relativity, which is Einstein's theory of gravitation.
In the early 1950s, he worked with Albert Einstein on the Unified Field Theory of Gravitation and Electromagnetism.
String theory is physicists' still-tentative strategy for reconciling Einstein's theory of gravitation with quantum physics.
Scientific theories, such as the theory of gravitation or the theory of evolution, have been so thoroughly tested and used to accurately predict results that they are cornerstones of scientific knowledge, not some speculative hypothesis.
It had long been known that some comets, such as Encke, persist in returning about an hour earlier than the Newtonian theory of gravitation would predict, while others, such as Halley, arrive a few days later than expected.
Therefore, on the one hand, general relativity is based on a principle which has only been partially corroborated and, on the other hand, it is possible to construct a new theory of gravitation based on the weak formulation but not on the strong one, as Dicke and C.
The use of gravitational potential which is a dynamical parameter also signifies that the existence of gravitational waves can also be predicted using Newton's theory of gravitation.
