Electrical and magnetic fields are cancelled by their opposites but gravity has no opposite, so nothing can stop it. If gravitons caused gravity, anti-gravitons could block them, but it isn’t so, and if gluons held the nucleus together, an anti-gluon stream could break it apart, but again it doesn’t happen, though anti-gluons are said to exist.
No physical barrier can block the spread of gravity because the quantum network passes processing on before any physical events occur. Gravity is then unstoppable because it always spreads, so no anti-gravity shield can block it.
A free-falling object accelerates as it falls to earth because the field moving it increases by Gauss’s law, so it moves faster. Einstein’s field equation relates this to space-time changes, as the earth is said to curve the space around it to make objects naturally fall towards it (Figure 5.9), but no mechanism for this is given.
In this model, space-time changes correlate with gravity because the quantum field causes both, so how does matter change space and time?
