    Yes. A particle is considered an excitation of a field. And a field is an operator valued distribution, the operators being creation and annihilation operators in Fock space (for a pleasant stay...). But what is described in Fock space?

    The brain is a simulator. Every moment of your waking life, from the moment in the embryo (whose particles directly stem from the big bang, contrary to the particles of a computer) to now, the world is projected in it. By your body moving. At the same time that massively parallel projection is given shape by massively parallel free streams of patterned spike potentials (ion currents flowing from the outside of the axon inwardly and propagating (unlike the potentials in computers letting electrons flow through wires, i.e., pulling or pushing). The brain streams never stop. In your sleep they cause dreams. There are constant feedbacks between the outside, inside, and the body, the actual you. Memory, i.e., learning, is engraved by strengthening connections (widening gaps).

    Your negativity regarding science and the future of our species. Don't stagnate within your polytheist fantasies. Either you pass responsibility for your own life to gods or you claim it as your own and stop scapegoating them. What happens in your life is under natural controls not supernatural controls.

  • Logical Necessity and Physical Causation


    Well, the exact calculations I don't have. You need to calculate the bound state of three massless preons interacting by a color gauge. For 3 bound quarks thats only done approximately. On discrete space. But you can basically use the Lagrangian of QCD, with modifications. The muon just has a larger spatial extent, because it's an excitation. The electron is on that scale still point like.

    If you call the mainstream trend of thought a fantasy, then they are right to treat you like a crackpotapokrisis

    Yes. But then who's the crackpot? They do use an unobserved mechanism. A fantasy. There does exist such a spontaneous symmetry breaking in condensed matter, and from there Higgs took the idea. But for that he had to introduce some weird unexplained vacuum energy. The preon model also predicts mass of particles from massles constitutes and also a Higgs particle, which is just a state of 6 preons, as are the W and the Z. They couldn't offer true counters, except irrational response.

    If you made a well motivated case for why it is a blind alley, that would be a different matter.apokrisis

    I mentioned the advantages. Symmetry between particles and anti particles is one of them.

    Sure. They are all roped together like nervous mountaineers on an unclimbed summit. You think the prize belongs to the solo athlete with grit and flair.apokrisis

    I don't want no prize but it should belong to the true theory. There is clinging to the standard (quarks and leptons being elementary).

    The muon g2 result is explained by considering the muon a triplet of three massless Weyl particles. Each with charge -1/3.

    Coming to think about it... How big is that prize? :grin:
  • Logical Necessity and Physical Causation
    All elementary particles are composite in some sense even in the Standard Model view. Quarks mix like neutrinos. Photons are effective mixes of Bs and W3s. The electron mixes with the anti-positron. We are back to Chew’s S-matrix bootstrap as far as I can see.apokrisis

    Yes, different neutrinos mix like different quarks can do. But the effect in quarks is much smaller due to their masses. Neutrinos from different generations mix. Quarks from different generations don't. Don't know what you mean by electrons mixing with anti-positrons. Anti positrons are just electrons. In the preon model there are no W3 pre symmetry breaking gauge fields. So the photon is just the photon. The non broken gauge state has never been observed. It's a fantasy to fit the facts, like the value of the VEV, of which the origin is unknown, which is because it's just posited on purpose. The same, but real mechanism is to be seen in condensed matter. Chew's bootstrap applies partially.

    So I don’t think preons are the answer. Or at least understood as a new deeper level of concrete particles - rather than gauge degrees of freedom - would be just to recreate the old atomistic paradox of why there would be any fundamental grain of matter at all.apokrisis

    I think the model has only advantages, like I outlined. It explains quark and lepton generations, mass, matter antimatter asymmetry (namely that there is none), etc. And it explains muon g2.

    But the standard rules. I guess it has to wait until:smile: higher energies will reveal it. There is still a lot of space between 10exp-22 and 10exp-35. Although tiny. But in comparison with a particle size, 10exp-35, it's a vast distance. Enough for three to form triplets. :wink:

    But there does seem to be now broad acceptance in particle physics that all fundamental particles are composite in the fashion of a soliton or other examples of topological order in condensed matter physics.apokrisis

    No solitons or gauge degrees of freedom involved in the preon model. There is no broad acceptance, that's the point. Everyone fears to say they don't believe in the standard. Their careers... :sad:

    The original preons were considered massive. I asked Harari by email and he was kind enough to answer. Massless preons could do the trick. He wrote me not to follow the "preon path". Dunno. Seems so clear. Like quarks before their discovery. I had a long conversation on physics stack exchange with a defender of the standard but in the end he couldn't offer substantial counters. The best he was left with was asking for the field Lagrangians. Well, yes... eeeh... Anyhow, good to know there is at least one person! :grin:

    Bear in mind that the Cosmos exists to serve the second law and thus its aim is to maximise entropyapokrisis

    You got it the wrong way round. The cosmos has no aim. A gas doesn't expand in a vacuum because it has an aim, an effect to be caused. You conflate aim with effect. The cosmos doesn't exist to serve the second law. The second law exists to serve the cosmos. To serve us! Living creatures, as part of the cosmos, have aim.

    So even without the inherent quantum uncertainty, the Cosmos is committed to the production of uncertainty at every turn.

    Just measure angles of triangles. Or the circumference of a circle and it's radius. If you're on a 2d spherical shell, the ratio is less than 2pi because the radius is larger. The difference between the two is a measure of curvature. If the sum of angles is less than pi than curvature is negative, and masses fly apart, repulsive gravity, dark energy. :cool:

    Yes. The Big Bang theory caused cosmologists, such as Einstein, to reconsider their presumption that the physical world was eternal, hence unconditional. So some, including Krauss, began to look beyond the BB -- pre-phenomenal domain -- for a First & Final Cause of our contingent universe. But most of those pre-BB causes -- Many Worlds ; Multiverses ; Inflation -- are still assumed to obey the same physical laws as our Real world. So, the question of the (noumenal??) Lawmaker is still openGnomon

    There is the possibility that there inflate two spatially 3d universes into existence around the mouth of a spatially 4d wormhole. If matter is confined to 3d and gravity spreads in full 4d, the two universes, once accelerated to infinity, can cause two new universes (one with lefhanded matter, the other with righthanded antimatter) to inflate from the virtuality into existence again. After which the cycle repeats. Dark energy solved!

Theories are not self-verifying but always remain hypothetical constructs, subject to the next round of possible verification or falsification from the data. — Neil Ormerod

    The standard Model is low energy approximation. I think it's pretty obvious that the basis particles are not basic at all. I asked the question about preons on several physics forums and even a philosophy part of a forum. I asked the question why the model is not more popular. But the questions were deleted and one banned me. It was against the standard. Quarks and leptons ARE fundamental. The preon theory has a different mass mechanism, but still predicts the Higgs particle. But not a Higgs VEV and associated Mexican hat. The weak interaction is not fundamental in the preon model. There's simply to much at stake for the defenders of the status quo. And its runners along. ‍♂️ There were no rational arguments against the model given, except the fact that no preons are observed. Which is a ridiculous argument since the collision energies are simply not high enough yet. But dont tellem that... There was another argument to be honest. The mass paradox, which can easily be solved by assuming the preons to be massless, giving massive triplets! So, only advantages. No matter antimatter asymmetry, explanation of particle families and explanation of mass, and only two basic fields! And an explanation of the muon g2 experiment. No preons used to explain that one.

    What surprises me every time is why a point is called an event.

    Is causality more fundamental than time? If time is reversed effect becomes cause and cause effect. Instead of acting from the inside we seem to be acted upon from outside. We would feel like a clockwork unwinding.

  • Atheism
    Subjectivity is truth." Discuss.Hanover

    In sincere humbleness I can do no other than agree. If we truly love the human being and want to fully explore our humanity we have to admit that all objective truths, and I mean all of them, are basically subjective stories. Which doesn't mean denying the absolute truth as independent of us, an idea initiated in ancient Greece (Xenophanes) which propagated in history to find a climax in the world of science, trying to land on this independent true reality but without actually touching it. An idea embraced by oldies like Plato (the mathematical realm, approximated by mathematical expressions) or youngsters like Sir Karl PimplePopper, claiming indeed we never will actually touch upon reality as we should always nervously try to falsify.

    No. We don't have to deny that idea. But what we do have to deny, is that, self-contradictory (paradoxically) as it might sound, the uniqueness of that absolute objective reality. It depends on who, or which cultural ensemble, or even which creature existing besides of us (which are created by the gods just as us) it's asked. They all have their objective stories. None of these stories should be given an advantage over the others. If we want to be truly human we have to admit that and let them all be part of humanity. For the benefit of all.

    It's the subjective truth!

    So, while I think gods exists independently of us, for all people and creatures, the atheist's objective reality is one of matter only. Or whatever other image. A tesseract reality maybe. Or a mathematical. Or a dreamtime reality. Take your pick. Why is so hard to concede? Because of that old Greek initiative still echoing today? And pretty strongly, I might add...

If the particles form a rigid solid, they are in tight formation. The information content, the entropy, is minimal. The interesting in formation is in between.

    So:
