Discussion Overview

The discussion revolves around the nature of the smallest known particles in the universe, focusing on the structure of matter, particularly atoms, neutrons, protons, and quarks. Participants explore theoretical concepts, speculative ideas about subatomic particles, and the implications of these ideas on our understanding of matter.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants assert that matter is composed of atoms, which consist of neutrons and protons, with electrons orbiting them, while others challenge the classical picture of particle structure.
  • There is uncertainty about the internal structure of particles, with some suggesting that quarks might be made of even smaller particles, leading to a potentially infinite regression of subatomic structures.
  • One participant emphasizes that quarks do not orbit but are arranged in specific configurations within baryons, and that the concept of "free space" in atoms is unclear.
  • Another participant expresses that imaginative speculation can lead to scientific discoveries, referencing historical examples of paradigm shifts in scientific understanding.
  • A later reply warns against unsubstantiated theories and encourages adherence to established physics, indicating a preference for discussions grounded in current scientific understanding.

Areas of Agreement / Disagreement

Participants exhibit a mix of agreement on the basic structure of matter while disagreeing on the implications and interpretations of subatomic particle behavior and the validity of speculative ideas. The discussion remains unresolved regarding the existence and nature of particles smaller than quarks.

Contextual Notes

Participants express varying degrees of certainty about the size and structure of subatomic particles, with some claims depending on specific theoretical frameworks. The discussion includes speculative ideas that are not universally accepted or proven.

Matter is made up of atoms. Basic. :smile: Atoms are made up of nuetrons and protrons with orbiting electrons. Also basic. :smile: Protrons and nuetrons are made up of orbiting quarks (not sure about the electrons for they have wave-like properties and I have not found anything saying they are made up of quarks.) Not so basic any more. :confused:

So far an atom is mostly made up of protrons and nuetrons. Since they are made up of orbitng quarks (UP and DOWN type) they are mostly free space. this means the quarks weigh a lot for there size (atoms are also mostly free space.)

A pattern also forms here. Everything is made up of smaller particles starting at the atomic level. So maybe quarks are also made up of smaller particles. These sub-sub-sub (super-sub) atomic particles could also be made up of sub-sub-sub-sub atomic particles. This could continue indefinnetly. If this was true the maybe at the sub-sub-sub-sub *10^100 level, particles of this level could shrink the distance between them by 1/10 of origianal. This could cause an effect that X number of levels up could shrink the distance between patcles of each level by 1/10 then matter that soud be on our size level actualy exsist in the space inside a nuetron. :eek:
Nothing says this is imposible!

So far,so good,the classical picture is okay.

Not exactly.Quarks don't orbit anything...The classical picture doesn't hold inside a nucleon.Electrons are fundamental particles.They don't seem to have internal structure.All particles have wave-like behavior:electrons,nucleons,photons,mesons,neutrinos,etc.

We don't know how big subatomic particles are.We don't know the exact internal structure of nucleons.We know there are 3 quarks inside and gluons mediate interactions between quarks."Free space" is something unclear.

This is the part where your imagination runs wild.There's unclear whether there are particles which make up the ones considered fundamental at this very moment.So anyone may imagine whatever he/she wants.You included.

Well, this is not entirely correct. I have written about this in my journal (entry 3 : on gluons and pions :https://www.physicsforums.com/journal.php?s=&action=view&journalid=13790&perpage=10&page=3 ) so it would be stupid to rewrite all that inhere. Quarks are positioned on a tringle or Y-shape in baryons, depending on the interquarkdista,ces at hand and therefore, depending on the energyscale...these properties are proven in the dual abelian higgs model.

Yes, i did let my imaginenation run wild, but so far a lot of discovories took some imagination to think up and then people used science to prove. When people first started to say the world was round, many others said they were really runing wild with there imagination.

As far as the quarks are concerned, orbitting was really just a guess but they have to have some way of giving a protron a 'edge'. Also they are not (unless i misread) 1/3 the size of a protron or electron, which means there is 'free space', and if there is not free space something must take it up the space or else we have a problem.

This was ment to be a 'what if' idea to get others to think on it.
 
lawtonfogle,

Welcome to PF. This site is not the appropriate place to let your imagination run wild -- personal or unsubstantiated theories are not welcome here, per site guidelines. We prefer to keep our discussion here on real physics. Please try to keep your imagination in check here.

- Warren
