The question now becomes since the centrifugal force can alter the acceleration of gravity, a shown in the diagram, does it also alter space-time at the equator?

Does General Relativity have a provision for the acceleration change due to rotation and the centrifugal force?

Can gravitation and inertia be identical? This question leads directly to the General Theory of Relativity. Is it not possible for me to regard the earth as free from rotation, if I conceive of the centrifugal force, which acts on all bodies at rest relatively to the earth, as being a "real" gravitational field of gravitation, or part of such a field? If this idea can be carried out, then we shall have proved in very truth the identity of gravitation and inertia. For the same property which is regarded as inertia from the point of view of a system not taking part of the rotation can be interpreted as gravitation when considered with respect to a system that shares this rotation. According to Newton, this interpretation is impossible, because in Newton's theory there is no "real" field of the "Coriolis-field" type. But perhaps Newton's law of field could be replaced by another that fits in with the field which holds with respect to a "rotating" system of co-ordinates? My conviction of the identity of inertial and gravitational mass aroused within me the feeling of absolute confidence in the correctness of this interpretation.

Since centrifugal force has the same impact as negative gravity; pushing mass outward away from the center of gravity, ...

That being said, if gravity was a force,...

was the rotation of the earth induced by an exothermic output stemming from the loss of gravitational potential?
