" ... the asinine effort by Tom to discredit my work."
James, your attitude makes me wary of saying anything at all to you. If you don't subject your work to criticism, and instead advise your critics to read everything you've ever written and ignore the contradictions, the work ends up being of use to no one but yourself. Which is fine, if that is all you want.
In any case, if your conclusions are true, nothing that I or anyone else does or says can discredit them. However, when you make statements like "Mass is the inverse of acceleration ..." and then go one to say that therefore relativity must be wrong, you betray a profound innocence of relativity -- Einstein already accounted for that possibility when he derived special relativity in the first place. Einstein's equation for rest energy, E_0 = mc^2, follows from E^2 = m^2c^4 (pc)^2, where p represents momentum. A massive particle of zero momentum must therefore have negative mass. No problem there -- physicists, particularly cosmologists, have plenty of uses for the idea of negative mass.
If as you claim, though, mass is undefined (it isn't) -- then defining mass as the inverse of acceleration only compounds the problem because it defines mass as existing only in negative form. Of course, we know this isn't true.
Edwin quoted Smolin's latest book (which I am also reading), "In general relativity mass can only be defined globally. ...as measured from far, far away (from infinity actually). In the case of local mass [...] there is no clear definition yet. [And] mass density is a similarly ill-defined concept in general relativity." These facts have long been known -- which is what led to the conclusion of my last essay that the source of all information is a point at infinity. (This is no "pi in the sky" claim, either; the mathematics, if not the physics, is rigorous and mostly understood.)
Now, how would you react if I accused you of making an asinine effort to discredit Einstein? (I don't think I've ever said such a thing to you -- though I might have said something similar to Pentcho Valev, and if not, I should have.)
Let's meet facts with facts, and forget the bluster.
I'm sorry to hear you were ill, and glad to hear that you are feeling better.
Tom
