EXPLANATION

About the model of the rail and the little wagons according to Newton's law of mechanics.
The presented solution of the animation of the little wagons seems intuitively correct. However an analysis according to Newton's laws shows it is wrong, which enhances the didactic value of the model considerably.

Then applying Newton's law to the model, by firstly to assume no friction or dissipative energy losses, such as air friction or rolling resistance, allows us to apply the conservation laws for momentum and energy on the system of the rail and wagons. Consequently apply the law of action to reaction between the teeth of the rail and the pendulum of the wagon. The impact of the force pulse from a rail tooth to the catch is not considered in detail, but one has to make some assumptions about the vibrating rails ea. the rail teeth are infinitely strong, the rail is absolutely stiff and the overall mass is much greater than that of a wagon.
In this case Newton's laws demand that whatever the mass (inertia) of the wagons, as long as it is smaller than that of the rail system, the wagon reaches the maximum velocity of a rail tooth in one cycle of the vibration. So the wagon travels along the track with a synchronous constant speed in relation to the pendulum movement of the catch and this is independent of the mass of the wagon provided the track is horizontal. Implicitly one assumed no reduction gear box between the wheels and the catch exits. (one to one gear ratio)

The outcome is astonishing, but it exactly demonstrates the point, whatever the inertia (rest mass) of the atoms or electrons, the speed of time of the cosmic field for each of the species of particles is the same. The confusing issue seems to be that all the other teeth along the rail track are not contributing very much during the lossless progress of the wagons. Of course air friction will be of some aid, but this condition cannot be applied to the inherent existence of the cosmic field and its perpetual atoms. However, then think what will happen if one changes the slope of the rail track, so it is not horizontal any longer. Then the teeth along the rail have a function of a brake (downward slope) or pulling action (upward slope). Then again the wagons experience the same force of gravity independent of their weight (mass). Since matter and anti-matter experience the force of gravity in the same way, both the rails (time and anti-time) should be facing upwards or downwards depending on the direction of the force of gravity.

In empty space the cosmic field seems to be freewheeling to the atoms, but in the environment of gravity they experience the force action of the cosmic field, also called sometimes carrier field. Since 2004 it is known that empty space has accelerated expansion. The free wheeling of the atoms cannot be any longer. The atoms are accelerated along their rail tracks going up hill. The rest mass does not change during the struggle uphill, because the acceleration acts as a force. So the width of the teeth on the rail does not change.

Note.
The visual display of the crank movement driving the rails seems to suggest that time and anti-time are 180 degrees out of phase, which should not be. It is a minor inconvenience of this model of animation.

The rail model really is valid. There is only one carrier in time serving all atoms and anti matter atoms as is shown in the theory of the 3D-gravitons for empty space surrounding the atoms. See the button ‘achievements’.
