Surely, gravity is a push from outside, not a pull from inside. Same applies to other forces of "attraction". How would anything be able to pull, even if it was made of string or whatever? The particles in strings etc are pushed together from outside too, not "attracted" together.If one wants to measure the "speed of gravity" one needs a short pulse of it.
Or are we going to suppose that "attraction" is the force of Love? One particle loves another one, so it moves toward it? If the feeling is mutual, then both move toward each other? If the second one dislikes the first one, then it moves away while the first one keeps trying to move together? I don't think such attraction/repulsion motions have been detected in the microcosm. Anyway, how can attraction actually exist in physics? It seems to me to be an utter absurdity.
Repulsion makes sense, because impenetrability would prevent two particles (that are more or less randomly moving toward each other) from going right through each other, but would instead bounce apart. But attraction would seem to rely on a magical property of matter or particles. Repulsion would be the same as momentum, I think. Mathis' ideas about spinning particles absorbing smaller particles polarly via external pressure and shooting them out equatorially via centrifugal force makes the most sense to me to explain repulsion, I mean besides collisions also explaining it. What's more explanatory than that?
