One of the issues that unfortunately hasn't come up in this discussion is the negative result of "table-top" experiments of relatively low cost, like ACME-II or that of the Boulder (Colorado) collaboration, which have measured a possible electric dipole moment of the electron (eEDM) to an extremely high precision. The zero outcome of those measurements, pushing the experimental bounds further and further, have ruled out huge classes of models beyond the Standard Model and the particles predicted by such models, in the context of CP violation and usually supersymmetry, up to energies unattainable at the LHC and possibly even at the planned next circular accelerator of CERN, with a circumference of about 91 km and a projected cost of about €20 billion.

Future Circular Collider (FCC) Feasibility Study, concludes in 2025, details are on CERN's website (where in 1990 the WWW was hosting the World's first webpage, the World Wide Web, being developed by Tim Berners-Lee, while working at CERN, was In 1999 named by Time Magazin, one of the 100 Most Important People of the 20th Century), highlighting the planned circumference of 90.7 km, an average depth of 200 m and eight surface sites for up to four experiments. The tunnel would initially house the FCC-ee, an electron-positron collider for precision measurements offering a 15-year research programme from the mid-2040s. A second machine, the FCC-hh, would then be installed in the same tunnel, reusing the existing infrastructure, similar to when the LHC replaced LEP. The FCC-hh aims to reach collision energies of 100 TeV, colliding protons and also heavy-ions, running until the end of the 21st century. Resulting in about 800 000 person-years of employment created. Projected cost is around €15 billion, spread over 15 years, significantly less than 20 as stated and the turn around on all this, should be ready to start smashing by 2030! 35 years to just get the LHC agreed and first operational, September 10, 2008. Taking only 4 years to make the breakthrough of the Higgs. I can't deny there is value in as you said, "table-top" experiments, absolutely! When you look at the fact the LHC exists, this isn't anything like going back to 1984 and spend the next 35 years waiting for the project to come online. The fundamental foundation, already exists. This simply enhances what does exist, creating new jobs, with so many other potential benefits, as pointed at with the unexpected one of the World Wide Web, having come about during a brilliant man, working at CERN, found a use case for its creation and being bright enough to do so.. my point is, there's benefits in both cases, in fact the more we have happening, the more progress should collectively become possible! 2027-2028: Decision by the CERN Member States and international partners - 2030s: Start of construction Context, physics case for LHC was made in 1984; took 10 years for the project to be approved, 25 years for the magnets to be developed and installed. 35 years and how much.. this is nothing by comparison.

@ownyourgov I think a good analogy would be writing on paper. You can plot the points, but what your writing with has filled in the line. So, if there is an infinite Cartesian plane of dimensional input, from either direction, then in any pattern or shape you could ascertain it's point of origin. Because time, as we know it, is based on revolutions of the earth around the sun. You can only follow that so far before it becomes something unrecognizable. It might be better to define time simply as distance, since in the space between two objects, or more, they can only exist within the confines of their dimensional distances together. This would be in any state they can share in the same moment. Like attracts like and all that. So I guess, the experiment would rely on what you're measuring. If, for example, all carbon shares the same state, that it has been that state of carbon, for as long as it has been in that state, then it is essentially as old as that state of carbon could have existed. Within the parameters of its existence. What your measuring is just as important as why your measuring it, I guess, so basically every experiment that can measure an input.

Although certainly the thought of building a weapon out of whatever ideas these guys have has often pushed research. See Manhattan Project. Of course we cannot do experiments, i.e. measure stuff, if we don't know how or cannot measure it. Is our "collective wealth" better spent else where? Perhaps but even CERN is not consuming a significant amount of that.

I find the discussion about “should we search for more particles” is framed in a somewhat narrow minded view. There is no doubt that there is more to find and a new particle accelerator would yield new physics but the question really should be inclusive of an economical frame: out of the finite resources (money) available, where can it be invested that would yield the greatest benefit to humankind? Is the answer a new particle accelerator or are there other areas of physics that would offer more benefit in the near future? Posing the questions to each expert as almost “is there even a point to continuing research” seems to side step the rationale behind the argument that maybe particle physics isn’t where money should be going.

The direction of physics should (perhaps) be modified substantially. There is a difference between knowing and understanding. Knowing could be defined as detecting patterns and then building a model based on those patterns. While, understanding is linked to a sort of answer which covers all the "whys" you could possibly pose. To give you a better description of what I'm talking about, we physicists have been thinking towards many things so far, but no one is asking what is 'we' or what it means by 'thinking'! What are we actually doing when we say that 'we think'? We probably need to go in a direction to 'understand' beyond modeling. It's like that now, we're using something (i.e., 'us') to understand things without knowing what 'we' is in the first place. That's why I think we need a much greater picture of reality, and upon that, we can go exploring further.

In the late 1960s, my philosophy professor, Thomas K. Seung, mentioned to our class that the Standard Model seemed to resemble the Ptolemaic model of the cosmos. Over time, Ptolemaic cosmologists had to add more and more cycles and epicycles to make their model agree with observations. It "worked" (could predict astronomical events), but it became exceedingly complicated. And then Copernicus and Galileo came along with a radically simpler explanation of the same phenomena. The same seems true of the Standard Model, adding more and more particles, sub-particles, and quirkily named properties (spin, charm, etc.). It works -- nuclear reactors and bombs are proof enough of that. But perhaps a new Galileo or Copernicus will come along to show us a simpler model, based on radically different concepts, that explains the phenomena in other terms ... and can be experimentally validated! (Lots of alternatives have been proposed, but none I know of have been validated by experiment.)

I'm a total amateur and don't grasp some of the nuances of this debate but, to me, physics has always been the search for "truth." How do things work? How do you explain that? What makes it tick? I don't think the question should be "Are we done with particle physics?", it should be "Is there something there that we can't explain yet?" If the answer is "yes", then explore it because you aren't done. It may be that the problem presents itself in the field of particle physics but the solution lies in some other discipline. In the end, aren't we looking for a "theory of everything?" I don't think that will be found until the rabbit holes of all disciplines have been explored because, by definition, a "theory of everything" would necessitate cross-disciplinary study. As for whether or not bigger colliders and accelerators are necessary, I just have to shrug on that one. That's not so much a question about physics as it is a question about finances and fiscal priorities.

I did my PhD in particle physics as a member of the ATLAS Collaboration. Sabine is right. We should stop running expensive collisions (in terms of energy, money and human time), as we don't have enough theoretical reasons to go down that path (not anymore, and that has been falsified by particle physicists since 2012). I can understand the great inertia present in large scientific collaborations to change path, but we should be flexible and do honest science, because in the end that is how science works, on the basis of accepting our failures. Otherwise we would still be looking for the aether.

I don't think any one particular "particle" is the keystone to anything other than a bit more understanding on the 'particle' level. Its a very isolated focused view in respect to overall field complexity ( which is undoubtedly where the forces reside and are influenced) I am positive that studying overall field dynamics is where we should be , including what we view as electromagnetic fields, gravity and the interaction of the forces described between time and size scales... you know the micro, macro and "standard "dimension which we reside in. Neutrino research as well as interest in the concept of Muons also seem important for me. Technology is advancing at such a rapid pace these days. Once we are able to simulate fields and better understand their interactions more holistically , I think we will gain much insight. It's all energy folks, even what seems to be "matter". Its all a matter of perspective and relativity. ( no pun intended). Just my 2 cents. 🤓🙏✨

What do you mean by "medium" exactly? My impression is that fields are mathematical objects which are useful for predicting experimental results. They assign a vector to each point in space and time and that's it. A mathematical abstraction. What we really can measure are things like currents, movements, forces etc. Smart physicists came up with mathematical abstractions which have certain properties and obey different laws, and can make sense of observed relationships between currents, charges, movement. And allow for theoretical derivation of results due to the fundamental laws of these fields being very consistent. But I have not yet studied quantum field theory (only electrodynamics & quantum mechanics) so there may be something deeper I don't know about.

Dark matter and Dark Energy, are very likely to be explained by Quantum Field Theory, also possibly changing perceptions of the "primeval atom" hypothesis, of Georges Lamatre. The muon collider can be viewed as an electroweak vector boson collider, emphasizing its potential to study electroweak interactions comprehensively, similar to how the LHC is often seen as a gluon collider due to strong interaction studies. Future accelerators are seen as essential, not only for further studying the Higgs boson but also for potentially discovering new particles that may be beyond the reach of current experiments. There are reasons to anticipate the discovery of new physics beyond the Higgs. The standard model, is not complete and the periodic table, an absolute shambles. Intresting that it would of course be Sabine making these statements. I disagree with many of her views and have laughed out loud at somethings she has previously said but nobody is perfect, even if they think they are.

The Poincaré group is a fundamental symmetry group that describes the spacetime symmetries of special relativity. It combines both translations (due to spacetime position changes) and Lorentz transformations (due to boosts and rotations). In theoretical physics, the space of physical states in a system with Minkowski spacetime (the underlying spacetime of special relativity) is typically a representation of the Poincaré group. More generally, it may be a projective representation (which amounts to a representation of the double cover of the group). In classical field theory, physical states are sections of a Poincaré-equivariant vector bundle over Minkowski space. The equivariance condition ensures that the group acts on the total space of the vector bundle, and the projection to Minkowski space is an equivariant map. Representations arising from the above construction (and their subquotients) are called covariant field representations. These representations are not usually unitary. For unitary representations, we turn to Wigner’s classification. QFT or quantum field theory, extends quantum mechanics to a relativistic framework. It involves solving relativistic wave equations (Lorentz/Poincaré invariant) and working with a Hilbert space composed of "Fock States". - No.. Fock... There are no finite unitary representations of the full Lorentz (and thus Poincaré) transformations due to the non-compact nature of Lorentz boosts (rotations in Minkowski space along space and time axes). However, finite non-unitary indecomposable representations of the Poincaré algebra can be used to model unstable particles. For spin-1/2 particles, a construction includes both a finite-dimensional representation and a scalar product preserved by this representation. Each particle is associated with a 4-component Dirac spinor that transforms under Lorentz transformations generated by gamma matrices. The irreducible unitary representation of the Poincaré group is characterized by mass and spin. These representations are given by two Casimir operators: the square of the total momentum operator (P2) and the square of the Pauli-Lubanski operator (W2). Interestingly, electrons and positrons have the same mass and spin but, are distinct as particles.

But since the Higgs was a profound summit in theoretical physics in the 70's, and physicists dreamed of the day when we would be able to detect its existance indisputably, and then we did detect, it to all intents and purposes, indisputably, I think we need to be looking for something like a Higgs theoretical profundity, by which we may re-aim efforts in the experimental reality - ie. The Higgs drove the enormous effort to build a LHC capable of detecting it. But that drive started in the theoretical. I think that is what Sabine is saying. There needs to be motive, or conflagration in the theoretical world toward a new profound physics goal, which may not necessarily be LHC based. Perhaps it is quantum computing based - necessary to discover a new mathematical summit or equation. Although partical collision has an addictive effect since discovery of the Higgs, you can just as easily say, well... we need a larger one if were to arrive at any new observable data with which to begin looking for a new particle physics summit.

In it's simpler form: SPACE: Unfolded Matter, emergent from rates of motion.

That kind of requires me to assume different subjective beliefs within my mind so that it paints a reality and geometry based upon that belief. A kind of reprogramming of the minds subjective paradigm to visit the different human realities that paint over the problem. > Not easy to do, but I am seeing some potential for some subjective human bias that may have taken past geometry and painted over (or tried to mush it into) the description of space-time. As if Albert and mates had to bring along something from the past to appease the gods of the physics jungle back in the day :) > P.S. I did attempt to bring in the concept of gravity between to points of small mass, but every geometry so far breaks the speed of light (gravitational fields must transfer information instantly). Kind of falling into that gravity issue there atm. > The thought experiments are quite revealing even if ultimately wrong in the end :)

I am certainly no physicist, but I'm thinking particles are just part of the wave; how can we measure the wave? Open to constructive criticism. :) @6Min. Would anyone in General Systems theory be helpful? Could you accelerate neutrinos? Perhaps those detected by Ice Cube? (I know, I'm showing my ignorance here, but I am the curious sort.)

The next step is not discovering new particles but studying particle production. What are the materials and processes required to produce a particle and particle properties? This and similar questions need answers not how many more particles are out there to be discovered.

@@clay-tw5gc From a physicist's perspective it is. The remainder is basically electrical engineering. Accelerators differ very little from other electrical power facilities. The core elements are similar to what's in your microwave, just far more powerful, and then there are lots and lots of high voltage power supplies. None of that is rocket science. The physics is really just energy input and empty space. You would be surprised how few people are employed worldwide to develop these technologies. It's a handful here and there at high energy physics facilities around the world. That's all it takes. ;-)

@@lepidoptera9337 The question is how did the first particle get produced in the first 20 seconds? However, before the first particle could be produced, charge, spin, color etc must pre-exist. How do these properties form a particle? Furthermore, how was the first charge, the first spin, the first color produced? And from what were they produced? What were the materials required in their production? By definition, there are no particles in a pre-particle universe. Thus a particle accelerator cannot be used to answer those questions. These questions need to be researched and answered somehow, someway.

@@clay-tw5gc There are no particles. There are only quanta of energy. We have been teaching this in high school for over 40 years now. All the properties of these energy exchanges are inherent in the Poincare group, which is the symmetry of empty space. Some of this was already known like 90 years ago, with the entire picture emerging about 60 years ago. You are asking questions of the deep past, scientifically speaking. ;-)

Particles are excitations in the quantum fields. The end of the line for finding smaller particles is the Planck length.
@lepidoptera93374 ай бұрын
Only if gravity is a conventional force, which it doesn't seem to be. People need to stop talking about the Planck length as some miraculous solution to all the problems they don't understand. It's not. It's not even a solution to the most trivial problems we have in quantum field theory, right now.

@@lepidoptera9337 Ok, well I think a trivial QFT problem, followed by your proposed solution, which ignores the Planck length, is called for.
@lepidoptera93373 ай бұрын
@@ZigSputnik A trivial problem of QFT is that all of its predictions are asymptotic, interaction-free plane waves at infinity, i.e. elements of the free theory. If we turn interaction on, then scattering happens everywhere, i.e. there are no free states, at all. Over an infinite distance the universe is always completely opaque. You can't solve that with some high energy cutoff scale because it doesn't happen at high energy. It happens at all energies and at all scales.

There are none so blind as those that will not see. Energy is defined in observer space and E = mc^2 shows mass is a phenonemon in a spacetime c^2 dimensionally remote from observer spacetime, i.e. mass = E/c^2. So Newtons gravity equation wherein G is a natural constant, F = Gm^2/r^2, is logically invalid and G should contain a c^4 term in the cgs units in which it was first measured, about 8.1 x 10^44. This means all old physics equations containing G must be revisited. Including the Dirac large number (5.7 x 10^44), and the Planck mass scale at 1.2 x 10^44 MeV/c^2. Correcting this error shows the Planck notion of a scale where all forces are equal is met by the electron which is in dynqmic equilibrium between an electrostatic force and a mass based central force, mv^2/r = e^2/r^2, with v very close to c, where e^2 = alpha.hbar.c introduces alpha as a relativistic factor. So dreams of a huge new supercollider are pointless, and the old Hierarchy problem of a large gap between the standard particles and the Plank scale is now gone. FYI, New Physics shows a derived value, G = 6.674273033 x 10^-11 SI units PS, there is lots more to tell. I have not yet found an e-mail address for Sabine so I cannot send her a 2 page analysis.

Gavin Salam is brilliant, but he’s also part of the business of science that Sabine left behind. He must take this point of view, because there are billions at stake. I’m sure he’s also a true believer, but the money and power that goes with his viewpoint shouldn’t be underestimated.
