Electrons constantly move because they are only one-dimensional matter, so photons can fill other dimensions to cause movement. The hybrid is held together because quantum entanglement unifies entities that restart at the same point. But when quarks combine into protons and neutrons, the distribution is symmetric, so atoms don’t usually move in any direction.
Yet quarks at a point still have free channels for photons to occupy, as higher generations show, so atoms can acquire extra photons to move as electrons do. Hence, light hitting a solar sail moves it, even though photons have no mass. The sail matter absorbs the photons hitting it which bias its distribution in their direction, so it moves that way.
Matter can move by acquiring photons that bias its distribution one way. It already trembles in all directions, so photons that increase the field strength one way make it move that way more often. The sail moves because the quantum field around it changes not because particles push it.
This also explains why mass increases as objects go faster. More photons mean more competition for channels, and more interference increases the processing that in this model is mass. The increase isn’t linear because interference doesn’t increase linearly with load, as networks like the Internet show. Mass then increases as movement increases, as relativity states.
Note that when matter acquires photons that make it move, they stay with it, so it carries on moving the same way. Physics calls the tendency of matter to carry on moving inertia, and assume it is an inherent property, but here it is caused by matter acquiring photons that bias its distribution.
Photons explain how matter moves but not how gravity works. The next section examines how a large mass like the earth can move the matter around it, even at great distances.
