Is Dipole Gravity the Fifth Force?

Dipole gravity is integrated into the gravity by virtue of the principle of general relativity. But the nature of dipole gravity is fundamentally different from Newtonian gravity because one can not be derived from the other.

The reason they are related as gravity is because the two forces share the same principle of equivalence within the paradigm of general relativity. However, if one assumes that an advanced civilization happened to discover dipole gravity separately from Newtonian gravity (they would eventually have to find a theory that incorporates both forces within the unifying paradigm, which will be equivalent to general relativity), it wouldn't be obvious for them to see that dipole gravity is a part of a grandeur scheme of gravity.

It would be an interesting mental exercise to speculate if it would be possible for a civilization to discover dipole gravity completely isolated from Newtonian gravity without first finding a guiding principle like general relativity.

Let's assume that some inventor(s) of the advanced civilization accidentally, while playing with a fast rotating hemispherical rotor, found the abnormal directional force, before anyone could have figured out a theory like general relativity, if that happens, the principal investigator would have named it the "fifth force".

Dipole gravity found in such a way would be considered having nothing to do with the conventional gravity because the way the force acts onto the other matters in the universe is totally different from that of Newtonian gravity.

So, in principle, there is nothing that prevents dipole gravity from being named as the fifth force of the nature.
