CERN language: "No matter how much energy we put into the fields, the particle never reaches the speed of light." My question: How can you expect to push a car faster than you can run? Maybe the speed limit is in the pushing ABILITY itself. A field must have a reaction limit, in spite of what Maxwell told you. Someone second-guess something. Testing your pet theory is not the same as questioning it, because a PERFECT MATH ANALOGY will FOOL YOU FOREVER just testing it!

[@utl94]

Well, nobody is expecting to push a car faster than the speed limit on running. Remember that we are not "running along" the particles "pushing" them down the accelerator. The accelerator is in place all along the acceleration path so there is absolutely no need to "keep up" with the particle being accelerated.

[@jnhrtmn]

@@utl94 You are missing the point. The speed limit may be due to a reaction limit of the field's ability to push something. Modern science is only math, so this concept in not in the math, therefore it's not a concept for anyone to realize, but I just said it, so it's really there. The field may have a reaction limit in its ability to push a particle.

[@utl94]

@@jnhrtmn I did not "miss" anything, I simply went with you saying "How can you expect to push a car faster than you can run?" This is what I responded to. Now: there may be a limiting time scale on quantum field interactions. As far as particle physics is concerned, any interaction between fields, and therefore particles, is the exchange of force carriers: the bosons. The massless ones propagate with the speed of light, the massive ones somewhat slower. From pure relativity, we have that any massive particle follows E = gamma*m_0*c^2 and this gives the velocity as u = c * sqrt(1 - m_0^2*c^4/E^2) Crank upp the energy to infinity if you like, the velocity u will not exceed c. I.e. your quoted "CERN language" is perfectly accurate as "No matter how much energy we put into the fields, the particle never reaches the speed of light." To answer your question why, I have to disappoint you. The existence of a propagation limit c is a postulate of special relativity, and, further, we have not observed any information propagate any quicker and within special relativity, such notion is frankly absurd. Also: "Modern science is only math..." Actually, moderna science is a lot more than mathematics, there are a lot of impressive experiments around. I can put on the hat that questions if mathematics is actually science.

A proton is a collection of 1836 expanding electrons and add a bouncing expanding electron makes a hydrogen atom. The electron ‘mass’ -9.11- multiplied by 1836 equals the ‘ mass ‘ of a proton. Adding 9.11 to a proton once or twice equals the ‘mass ‘ of the neutron. No energy, charge, photons, waves, spin, fields, potential, quantum,quarks, space- time, information etc. The expanding electrons do it all.

I first thought of posting this comment on the materialising of artificial intelligence part of "science", then I thought (backwards) why give any publicity to that, when "particles" can be made so "easy". The comment is this....! I just happened to finish listening to an (Etruscan) proving (with a scientific method such as DNA sequencing/biology), for over an hour that an (Etruscan) he was not, and in doing so I finally understood what science is. It basically steams up to this....! (I am, but I cannot think ((why)). Give me something to calculate, and then I can think about that, and therefore as a consequence ((be)) related to something/anything/somehow). Now that I have understood what "science" is, I am left with a more (triple component) puzzling question, (for the moment being). One of being.....! Is that very very dangerous, is that very very liberating, or is that simply very very calculating......!?!?

3:38 is wrong. Electrons do not "gravitate" around the nucleus. Gravity doesn't affect them.

[@PRG888]

Why just adding protons and neutrons, make elements have so many different properties

[@utl94]

Neutrons stabilise the charges nucleus. The charge of the nucleus determines how many electrons will bind to it to form a neutral state. Almost all properties of the different elements are chemical for everyday use and the chemical properties are determined by the number, the density, and binding energy of the electrons.

[@noisywan]

Is there really a fundamental particle? Every fundamental particle must have fundamental particles so it should be impossible to call a particle as fundamental. It's temporary for that time.

[@schmetterling4477]

There are no particles at all. There are only quanta. Quanta are irreversible energy exchanges. For the purposes of high energy physics the difference doesn't matter, which is why the majority of high energy physicists will tell you about their mental model (which is false), rather than the real scientific explanation, which is tedious to use in these limited scenarios.

[@tofu-munchingCoalition.ofChaos]

Naïvely one would think that they are elementary particles. And in a sense it's true (they are not composed of states). But they are nevertheless not strictly elementary in the way the Lagrangian is constructed. Quarks are composed of a "left handed version" and a "right handed version" without mass. But not that they are decomposed of two particles. They oscillate between these two versions by interacting with the background Higgs field. So what we call a "quark" is an interaction of osculating versions of two elementary particles and the Higgs field in the Lagrangian. The state however can't be split in the vacuum associated to our current state we are in. The same goes for the electron btw.

[@stayfocused6848]

Re: "we think gravitons will cause gravitational waves but we havent found them yet ". um... Gravity is only a description for space time curvature effect that mass causes itself so you wont find it. Spacetime is made up of the other particles.. so how do you bend a quark or an electron.. the theory is full of holes. I am sick of scientists self congratulating how clever we are. Need to be more humble. we know less than 5%

[@schmetterling4477]

We don't bend quarks and electrons. Quarks and electrons are irreversible energy exchanges between different parts of the vacuum that we call "systems". The problem with "gravity" and "the graviton" is that it interferes directly with the background that is required to define what "energy" is and "where one system begins and another one ends". Our language is a good macroscopic approximation for the classical physical vacuum that creates everything else, it is not a good approximation for the the non-classical vacuum.

They are both irreversible energy exchanges. The structure of these exchanges is predicted directly by two facts: space is three dimensional and all of physics is relative.

[@utl94]

@@schmetterling4477 "Irreversible" in what sense? I am thinking about annihilation and pair production.

[@schmetterling4477]

@@utl94 Irreversible in the sense of open systems. In an annihilation event we take two "local" massive quanta and we turn them into two massless ones. The result is that the energy in our photons is now leaving the interaction point at the speed of light. Because one can't catch a light beam those two quanta will never recombine into the two original massive quanta, again (at least not with anything resembling a macroscopic probability). This is clearly spelled out in Copenhagen, already. The Schroedinger equation describes a closed and isolated system (which is fully reversible), the Born rule an open, irreversible one.

[@utl94]

@@schmetterling4477 Well, recombination happens all the time in Quantum field theory as per the Heisenberg uncertainty principle and the path integral formulation. As for the Born rule, it may be applied to the solutions to the Schrödinger equation as well as to the solutions to the Dirac equation. The Born rule and the solutions to wave-like equations do not form a dichotomy. I don't get the "[i]Irreversible in the sense of open systems" idea.
