In the general relativity theory, the cause of gravity is arbitrary.
Regarding the new gravity theory originating from neutrinos, fundamentals are momentum of neutrino traveling at light speed with almost no mass. Therefore, at least slow moving object (Mercury's perihelion advancing), and at least the observer does not move (ray bending nearby fixed star, delay at time on stellar surface) and other problems, it is considered that the general relativity theory can be applied as it is.
Regarding the general relativity theory, the theory quite correctly telling the nature (behavior) of gravity, although the cause of gravity is unknown.
Regarding the real cause of gravity, it is only changed into the elucidation from being unclear, and falls outside the scope of general relativity theory. And it does not prevent achievement of theory of general relativity theory. However, it may become obvious later that the case that it will not go on with the conventional theory as it is.
It returns.
