Till today, there is no single model available that fully incorporates the standard model of nuclear physics, quantum mechanics and general relativity. In this context, by considering the strength of Schwarzschild interaction as ‘unity’, it is possible to show that, 1) There exists an elementary charge connected with strong interaction, (es); 2) Strong coupling constant is equal to the squared ratio of electromagnetic elementary charge and strong interaction elementary charge. 3) Electromagnetic interaction and the strong interaction both associated with two different gravitational constants (Ge,Gs,). 4) Quantum mechanical constants are secondary physical constants. 5) Currently believed average binding per nucleon is equal to the gravitational self energy of proton. 6) Proton’s magnetic moment is equal to {(es.hbar)/(2mp)} and neutron’s magnetic moment is equal to {(es.hbar)/(2mp)}-{ (ee.hbar)/(2mn)}. 7) Nuclear charge radius is equal to (2Gsmp/c2). 8) Root mean square radius of proton is equal to (√2.Gsmp/c2). Proceeding further, nuclear stability, nuclear binding energy and magic numbers can be understood in a very simplified manner.
