Dear Peter,
Good to hear from you. I will reply to some of your comments below:
"Having spent a good part of my career as an instrumentation specialist watching the highly relativistic beams in RHIC, designing pickups to measure their various properties, and spending a little time thinking about just what i was actually looking at, i find your unconventional approach to the implications of SR hard to mix with my pretty much congealed worldview of how things behave relativistically."
First, I am glad that you have an awareness that your views reflect a particular worldview. Since my worldview is probably very different, it is not so easy for me to discern which of the things I mentioned you find "hard to mix" with yours:
a. Dimensional diminution is mathematically consistent with Lorentz contraction at speeds less than c, and dimensional reduction is consistent with the complete Lorentz contraction of a body characterized by v=c.
b. I am unaware that anybody had ever pointed out the invariance of absolute dimensionality or the homodimensionality of space, but I suspect that is just because it was "too obvious".
c. Probably the most novel idea in my paper is that one can assign coordinate frames to speed-of-light objects as long as they are 3D, not 4D, and I made a case that this is not only consistent with SR, but hinted at by other parts of the theory, such as the fact that null-vectors have only 3 independent components. I think the resistance to the idea does not come from SR but because this realization is genuinely foreign to the contemporary worldview; It is like a piece of a jigsaw puzzle that doesn't fit anywhere. My reaction is simply that after over a 100 years, special relativity still holds some surprises (and that is nothing compared to the analogous claim in the second paper, ha!)
d. The claim about magnetic fields being line integrals of dimensionally reduced versions of electric fields seemed visually so obvious to me that I did not bother to design diagrams directly comparing the force field of a Coulomb field and the magnetostatic force field of a current, but I am coming to regret that now because, to my shock and bafflement, apparently it does not seem obvious to others. Let me ask you as well: When you compare the direction of the forces of a Coulomb field and a magnetostatic field of a current, does this relationship not immediately jump out at you? The force field in one has spherical symmetry, and the force field of the other has circular symmetry, which, when integrated over the current, gives you just the relationship I claimed. More complicated field arrangements make this relationship a lot less obvious but that doesn't change anything because this relationship holds at a differential level. Of course, the mathematical evidence in the appendix requires that it is already recognized that v=c implies dimensional reduction. Maybe that is what you had difficulties with?
"Hard to get a sense of just how the pieces fit together, what happens to the scale invariant properties of various models,..."
I am not sure which models you are referring to, but let me say that I reject scale invariance as a fundamental principle of nature because the ratio of different powers of length changes with scale. Most relevantly to us, the relationship between surface area and volume changes with scale. For example, a ball of radius 1 meter has 100 billion times as much volume per unit surface area than a ball of Bohr radius. When you consider this together with density, this profoundly affects the behavior of objects at different scales. I consider this at bottom the reason why, for example, we don't see large rocks floating in the air or why only planet-sized or larger objects eventually turn into round balls. To paraphrase Philip Anderson, as far as I am concerned, bigger is different.
"Assumption i guess has to be that everything you're doing is consistent with SR, that the equivalence is either proven or provable."
I listed the four major claims of my paper above. Tell me please, so I have input from an outside perspective, which of the four you are skeptical about (more than one choice is of course okay)
"Will part two address the quantum? "
Absolutely! This is the reason my paper is getting delayed. I had originally intended to only touch on some quantum concepts, but then I realized that it is really hard to just try to give a brief glimpse without it being confusing. So I have kept adding details, and as the result the paper is getting longer, and I am still not done.
"Clifford algebra is the language of QM. What is missing in mainstream is the geometric interpretation of the algebra. Geometric product of Geometric Algebra mixes dimensionality. For instance the product of two lines is a point and a plane. I'm not aware of any calculations in the literature showing some sort of smooth deformation (of what? geometry of electric and magnetic fields?) during evolution of the geometric product, showing just how two lines gradually morph into point and plane during dimensional abatement or dimensional 'enhancement' (got a better word for this?)"
Although my knowledge of Clifford Algebra is very little, I tend to think that it might hold the key to some profound insights yet to be discovered. I don't know enough to be able to assess your claim that it is "the language of QM". My first reaction is that we use different mathematical languages of QM depending on our needs. Whether we use Hilbert spaces, Path integrals or Clifford algebra, it seems to me, is dictated by the physics.
As for how the geometric product of two vectors "happens", I suspect that it does not reflect a smooth deformation of the kind you wonder about, but instead reflects a system of symbolic manipulations which exhausts the ways in which two vectors can be usefully combined in a way that conceptually qualifies as a `product'. I take this `exhaustiveness' of Clifford Algebra to be its strength.
"Curious regarding how your ideas might be applied to details of the interaction of two geometric wavefunctions (comprised of point, line, plane, and volume elements)."
Well, one difficulty I see right away is that wave-functions live in configuration space, whereas my ideas apply to real space. If anything, it seems to me that it would have to be the path integral which is affected by them.
Thank you for reading my essay and your thoughtful comments. I will read your essay soon and provide feedback as well.
All the best,
Armin
