The nuclear force acts only between nuclear particles, be it nucleons, mesons, or quarks and gluons, depending on what level of detail you want to describe nuclear phenomena. The gravitational interaction acts on all objects that carry energy, thus besides nuclear matter also electro-magnetic radiation. Therefore, it is logically not possible that gravitation is a residue of the nuclear force.
To answer my own question, it seems that it may not be very feasible. In this scenario there cannot be gravitational attraction between two leptons or between two photons or between non-hadronic particles. This can change the big bang picture. But this possibility should be ruled out either experimentally or with strong arguments.
In unified theories ( e.g. string theory etc.) all forces unify around Plank scale where all 4 forces are one and the same. When evolved to low enery they appear to be completely different . These forces are strong, weak, electromagnetic and gravitational.
Of course at low energy nuclear force is same as strong force: the former is between nucleons and hadrons ,and the latter between quarks and gluons
The strong nuclear force is caused by black hole singularities in the nucleons, which each causing a centripetal flow of energy quanta in quantum steps from a distance of approximately the Compton radius.. Each nuclear flow is fed by fine tuned flows of zero-point energy, via quantum steps from the "visible" horizon of the Universe. These latter flows satisfy the fields of gravitation. The access to the zero point energy is matched by the expansion of the Universe, as if it is a "black hole" itself .
This solution requires that the energy conservation extends to mass in a field of gravitation.
I have proposed the Harmonics Theory which, from a single premise relating to fundamental laws being non-linear, predicts the entire structural scales of the Universe. As a byproduct it expects that energy is continuously creating smaller scales. This means that at all scales energy is moving to smaller scale and so the standing waves that are particles have very slightly weaker outgoing waves than incoming ones. This causes both gravitation and the cosmological red shift. Particles gain mass with time and so new light is bluer, old light does not change frequency, there is no motion. There is agreement between the redshift and the strength of gravitation. We can also understand the LNH (Large Number Hypothesis) because at a radius of 10^40 of a nucleon, the spherical surface meets 10^80 other nucleons and so that the Universe is opaque beyond that.

Every force has its respective field particles, like Strong force has particles associated called gluons and the nuclear force can be said the residue of strong force (as in nuclear force associated particles are pi mesons (composite structure of two quark flavours and gluons)). But gravitational force can not be said the residue of nuclear force because the field particle associated with gravitation force called graviton, has spin two while gluons are spin one particles. There may be another explanation taking the range of the particle depending upon the mass of mediating field particles.
Chong Qi. I agree with you. Nuclear force is slightly longer range than the strong force. Gravity we experience is due to assembly of very very large number of particles.
It is well known that nuclear force is a residue of strong force. The mediating particle for strong force is gluon and mediating particle for nuclear force is pi meson.
The ratio of energy and force does not allow that. Because energy is the power to do work, and force is the cause of doing work. If the residual gravitational force is another force, then the energy is not stable.
The response is yes if we are using the current accepted theories… Onto base of my perception of our surrounding the separating the nuclear force and gravitational force is not so good to think, because can build such a model where the nuclear force is analogs to gravitational force…
Is it possible that the gravitational force is a residue of nuclear force?
It is an excellent question.
I am glad that you ask this question because I have developed a new theory of gravitation, called "Dynamic Medium of Reference" which relies on two pillars :
- an extension of Lorentz-Poincaré’s theory in the domain of gravitation,
- an improvement of Lesage's theory,
and in which the gravitational force may be a residue of the nuclear force.
Matter is made of atoms which are made of electrical charged particles (electron e- and proton p+) and neutral particles (neutron).
So there are many electric forces between all these electric charges.
But macroscopically matter is electronically neutral, because it contains a very large number of atoms (just 12 grams of Carbon contain N_Avogadro = 6.10^23 atoms of Carbon).
We can transpose the previous reflection to the nuclear force which explains the cohesion of the nucleus of the atom.
At a macroscopic scale, the number of atoms is so large that the resultant force is close to zero, but not rigorously null.
The remaining residue would be the gravitational force.
For the moment, the theory "just" explains gravitation, but I am writing a paper where it will also explain the nuclear force (see Appendix A to have a first link with the nuclear force). An experiment will be proposed to test the theory about the nuclear force.
Following is what I posted on Nov. 12, 2014. I repeat it here.
