Dear Ian,
Thank you for your message. I am reposting part of a message I wrote today to Jason, because, I think it is relevant to your topic. That is, unless I am wrong in the example I give below:
....I think its too early to judge who has the truth. I think relativity theory is clearly wrong. I think many other ideas carried along by theoretical physics are also wrong. Why should anyone care what I think? My conclusions will certainly not win any respect by themselves. There is only one place for me to participate and that is at the fundamental level. That is where the changes, as I see them, must begin to be made. I think it is the only place where I have any chance of scoring points. So, I mentioned elsewhere, in another message, the idea that defining mass in f=ma as being a unique fundamental property requiring its own unique indefinable units of measurement was a guess, and, I add now that it was a wrong guess.
Why should anyone care? The equation f=ma is long established newtonian physics. It is very successful up to the point where Einstein's theory corrects it. The success of the two of them together make the original theoretical interpretation of f=ma appear to be truth. That is a very big hill for any challenger to climb.
You (Jason) said: "In an earlier entry, I asked: what causes gravity? I still think the question deserves an answer."
I missed seeing this. I have looked back and could not find a previous message where you asked about the cause of gravity. But, now to my point for bringing this up now. The answer, as I see it, to the cause of gravity lies in reinterpreting mass in f=ma. Mass should not have indefinable units of measurement. It should have units of some combination of distance and time. When this change is made, then a possible answer for what causes gravity appears immediately. Again, why should anyone care about this viewpoint? If we mess around with mass then almost everything will change. Why change that which has worked so wonderfully well in practice?
I will offer a possible reason. The universal gravitational constant is equal in magnitude to a physical event. Consider two ideal, simple protons at a distance of separation equal to the radius of the hydrogen atom. I am using protons instead of neutrons because I want to avoid getting into a discussion about the nature of neutrons. Completely disregard electric effects. I am speaking only about gravitational effects.
An observer on one of the protons believes himself to be stationary. He sees the other proton approaching his proton due to the force of gravity. I will refer to this as the local acceleration of gravity. Now the point: The magnitude of the fundamental gravitational constant is equal in magnitude to the square of the local acceleration due to gravity of one proton toward the observer's proton multiplied by the square of the distance between them at the instant that that distance is equal to the radius of the hydrogen atom.
I have to refer only to the magnitudes because, the units do not match. Now I refer anyone interested back to my point regarding f=ma. If the units of mass are corrected back at the beginning of theory, then the units in the above conclusion match and I do not have to refer only to their magnitudes.
