Mass is much faster than energy. Mass “blinks” into existence then immediately out of existence. The RMCM asserts that Points don’t move. What moves is Density of mass.
When an electron slides into a valence it converts to mass built shell.
E= mc^2 works; we know this. It is just too abstracted to be workable in both GR and QM.
We refine Einstein’s theory to read E=DC^2. We can use this model to also Explain Entanglement as density that flows instantly between to sources.
