  1. I try to gnaw away at the ignorance I spot in other people up to the point where it's at equilibrium with my own ignorance. Once that point is reached, I can help them no further. The Grapes of Wrath. Saluting the brand new theory of everything that will some day supersede the current model, and a hunch tells me it's going to happen here, probably by someone whose name is something like an amalgam of Latin words roughly equivalent to "the powerful and truthful one".
  2. Hello. Welcome to the Forums. As I understand, you should make your point clear without people having to click on any links. But the mods will tell you in more detail. At some point in you pre-print, you say "we arrive at the closed-form Lorentz-covariant expression:" (my emphasis). And said expression happens to be, \[ C_{ij}\left(x,x’\right)=\frac{\hbar}{\pi²\varepsilon_{0}c³}\partial_{t}\partial_{t’}\left[\frac{\delta_{ij}\left(ct-ct’\right)²-\left(x_{i}-x’_{i}\right)\left(x_{j}-x’_{j}\right)}{\left[\left(ct-ct’\right)²-\left|\boldsymbol{x}-\boldsymbol{x}’\right|²\right]²}\right] \] Then you say, "This expression is manifestly Lorentz-invariant and[...]" (again my emphasis). So what is it, Lorentz-covariant or Lorentz invariant? Those are different things. An invariant is a zeroth-order Lorentz tensor, while a covariant quantity is a 1st (or higher-order) Lorentz tensor. Another concern of mine is : How can a state like the vacuum, of which you know virtually nothing (pun intended) be in a pure state (which in quantum mechanics means "a maximally determined state"). IOW: How is the most undetermined thing in the world in a state that is maximally determined in the quantum formalism?
  3. How local what is? Properties of a manifold can be local or global. An evolution law or differential equation can be local or non-local. There's not such concept as being 'a little local'... Locality Say what?
  4. Exactly. Thank you. I think most people who try to come up with their own 'theory' miss this first and foremost.
  5. No. New physics doesn't do that. Example: So the old theory is but a particular case of the new theory. An approximation on the new theory. AKA: asymptotics. The old theory is alive and well, forever breathing, well protected in the guts of the new theory. Pristine. Untouched. Loved by all who know. Finally really understood. No observations re-defined. No harm done. No replacement. No ideological cleansing. Analytic continuation through and through.
  6. For a flat manifold "locally" and "globally" carry no significant difference. You may have non-vanishing Christoffel symbols as a consequence of your choice of coordinates (like picking polar coordinates to describe the plane R²), but nothing's going on as concerns curvature and topology, as calculating the Riemann tensor will tell you. I, among others, fail to see what you're getting at. Every smooth manifold is locally flat. I'm even more at a loss as to what any of this has to do with a theory of all the parametrics of elementary particles, AKA TOE. Actually not true. Flat manifolds can have non-trivial topology. But the rest of my comment is quite alright. I can feel @KJW breathing down my neck... 😅
  7. Really? You've been mentioning the Lie derivative, and the Riemann tensor, and manifolds, curvature, etc, for quite a while now. What are those about if not mathematics? Thai cuisine? Seems to me you're going in circles around the rabbit hole of mathematics without quite venturing to stick your head in it. Ok. So what's up with that? There's no limit to how small one can be for any pairing of variables, while the other leads to a combined uncertainty (for the non-commuting variables) of approx. h-bar. Where do we go from there and how does it relate to a theory of all free parameters of the standard model + gravity, which is what TOE means?
  8. "Periodic-Table experts"... Hmm How does that go? Call 911(1/2) for a periodic-table expert?
  9. So what we're getting here is nothing but a cluster of last-ditch attempts to get saved just in cosmologically-plausible time --in a manner of speaking. That knowing --if those civilisations are in any way intelligent-- that the farther away you are, the least likely you are of being of any help? One problem with your theory (by no means the only one) is that it's based on a number of extremes (and I'd need a double emphasis on the word 'number"): The chances of something very unlikely happening is, say, 0.01 (one in a hundred). The chances of another (independent) very unlikely thing happening is, say, another 0.01. (one in a hundred again). The chances of both happening, then, is 0.01x0.01 = 0.0001 (one in a ten thousand). You get my drift: Not bloody likely!!
  10. Transforming lead into gold (as found out in the LHC) is not about re-arranging electrons, but about re-arranging nucleons (protons and neutrons). BTW, it's an extremely low-efficiency process (requiring billions of years just to produce a pair of earrings).
  11. Exactly!! That's the reason why she loves aardvarks but has no regard for anteaters.

    Very interesting. Thank you. I remember having thought time ago something along the lines of "what if the honest-to-business symmetry group of GR is not as humongous as the group of all differentiable transformations of the coordinates, but something smaller and in a sense less unwieldy"? The diffeomorphisms would be a mathematical convenience, but the physical group, being rather about classes of valid systems of accelerated observers. Not sure if the starting point of this proposal stems from a similar motivation, but it seems to go in a similar direction.
  13. This is interesting.
  14. So how does your idea involve fractal dimensions? I'm every bit as intrigued as I was before. Fractals involve boundaries that are not measurable. Every answer that you give me is more and more profusely worded and farther and farther off-target wrt my question.
  15. There are infinitely many time scales. But that doesn't involve fractal dimension necessarily. How does your idea involve Haussdorff dimension? I'm intrigued.
  16. Just an innocent question, before I become acquainted with the finer points of the discussion: How is this thing 'fractal'?
  17. I've emphasised where you started to go wrong: This looks like that, so basically that's what it is. You were as good as lost from there.
  18. How can I be part of a problem? What problem? What is it that's wrong with physics that you set out to put right? OTOH, this doesn't look like a discussion on classical physics. It seems more like a speculation to me. And you didn't address any of my criticism. It's not about 'disparaging' anything. It's about stating clearly what it is that you're addressing. And then addressing any possible criticism.
  19. So what's the point to be discussed? You talk about photons in terms of "inertia in transit" which does not single out photons in any way. All energy moving from A to B would be inertia in transit. You also say that dark matter is without inertia, which is sure to be doomed as a useful physical concept. Not that anybody has tried to accelerate a galactic halo, though. Anything containing energy must possess inertia. Dimensional analysis only gives you a zeroth-order approach to physics. It weeds out lots of possible silly mistakes and allows you to qualitatively predict the parametrics of physical problems. But trying to guess the whole of physics from dimensional analysis is akin to figure out global economics by counting beads.
  20. You're not making sense. You need a then and a there. Force is not an attribute of mass. Nor are either of them (force or mass) space-time references.
  21. I agree with the criticism. Also, whenever you write down t (for time) or d (for distance), you should immediately ask yourself: Time and distance with respect to what? That these concepts are mere references that require coordinatisation was first realised at least in 1632.
  22. Read the comments on Stackexchange. Then read about "Zeno's paradox". And then go for the real thing "the quantum Zeno effect", which is no paradox, but an actual effect.
  23. Supporting? Yes!! Endorsing? Never!! That's Mrs Tilly's way.
  24. Loves soot, hates coal. She likes a dribble, but dislikes a trickle. Go figure.
