Where the nuclear binding energy comes from?

There is reasonable doubt about what nuclear binding energy is and where it comes from. The logical source is gravity, where the pull force would replace the binding action. But this scientifically confirmed weak force is no match to nuclear energy. Hence, there has to be a better way to make nuclear binding energy from the pull force of gravity. Here is a solution, the force of gravity when applied to molecular matter is calculated from mass and the distance between two objects. However, the available nuclear energy has to be viewed from a different perspective. In molecular matter, nucleuses of atoms are separated by clouds of electrons, creating distance between nucleuses in the molecule. On the other hand, the nucleus of a single atom has no space between mass components. Hence, the pull force within the nucleus system can be exponentially higher, equaling energy required to split the nucleus of an atom to its component parts. Therefore, gravity would be the source for nuclear binding force in the nucleus and equal to the level of obtained nuclear energy.
