Why do cranks invent meaningless terms?
I don't think the phrase "speed of force" is really meaningless.
However, a single force can't literally have a speed. I think they are
referring to the delay between the action and the reaction.
General rule for all mechanics: For every action, there is a
reaction. In other words, if body 1 exerts a force on body 2, then
body 2 exerts a force on body 1 that is equal in magnitude but
opposite in direction. However, what varies with the mechanics is the
delay between these two forces.
1) According to Newton's Laws of mechanics, there is no delay between
the action and the reaction. Both forces are simultaneously equal in
magnitude and opposite in direction.
2) According to Maxwell's equations, there is a finite time delay
between the action and the reaction when electromagnetic fields are
involved. The forces at different times are equal in magnitude and
opposite in direction.
3) According to SR, there is a finite time delay between the action
and the reaction always. The forces at different times are equal in
magnitude and opposite in direction.

When people are talking about the "speed of a force", they are
generally talking about the distance between the two bodies and the
time delay between action and reaction. In GR, the "speed" both
electromagnetic force and gravity is "c".
According to

The speed of gravity is the cause of Mercury's anomalous precession.

S P

The force exerted by the sun on M doesn't act till the planet is at M'.
Therefore, the direction of that force is always forward of the sun, towards
P, causing an increase in precession of the ellipse.


SR contradicts itself. Why try to defend any of it?
