# Is there any time dilation in between quarks or nucleons?

Mass curves spacetime creating a gravitational gradient/time dilation, and mass is mostly energy when considering the miniscule mass of the quarks themselves. This implies that the dilation is caused by the energy and not the mass of the subatomic particles. I've understood quarks as bouncing around inside the nucleon radius with the Gluons acting as springs. If the springs would be constantly expanding/contracting, wouldn't this mean there would also be a constantly changing potential in the color field/strong force, and thus a change in time dilation due to that energy?

Nucleons are complicated quark-gluon systems. If you smear out the energy density and model a nucleon as a sphere of mass around $$10^{-27}$$ kilograms and a radius of around $$10^{-15}$$ meters, you will find that the gravitational time dilation, which differs from 1 by something on the order of $$GM/c^2R\sim 10^{-39}$$, is completely negligible.
