I suppose you wouldn`t value his opinion? LOL
einstein_vishnu - dought regarding equivalence principle i have some doughts regarding the principle of equivalence.we have seen that the inertial mass and gravitational mass are same.now consider the nucleus where in nucleons are binded due to which there wiil be mass reduction,this is inertial mass.then how come there is decrease in gravitational mass?,if this decrease is only in inertial then the raio of two masses would be different depending on the binding forces.is there any real explanation for this.i feel we can to some extent show that equivalece priniciple is not valid
