The Standard Model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe.

Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model.

Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy. It is not quite a complete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do.

Gluons mediate the Strong Force. They have no mass, no electric charge and no weak charge. So depicting gluons visually is a real challenge. To begin with, there are eight of them, and each carries a combination of color charge. Secondly, there are no free gluons, they exist only virtually when two quarks interact.

Third, since the gluons have their own color charge, they generate secondary virtual gluons, and these generate other gluons, ad infinitum. This means there is such an ongoing storm of these gluons that the whole process is impossibly complicated.

But undaunted, we press on. We know that when gluons cause two quarks to interact, the quarks swap color, and since color is conserved, the gluon must have at least two colors of its own.

Next, we know that the strong force mediated by the gluons increases in strength, as the quarks get farther apart. This means the gluon field is what is called a flux tube and leads to a gluon shaped like a string.

  • love the video man

  • how trust-able is this anyway?

  • very interesting thanks

  • "Tight Borromean rings" apparenty is the best image-searchable description for the octahedrally cube-corner-dimpled object I was trying to describe. It's basically composed of 3 orthogonally-oriented interlocking donuts. I'd suggest the dimples are similar to cube-corner reflectors in that they have a influx-directing/outflux-orien­ting property capable of greatly altering gravitational binding energy conservation in nucleons. That gravitational binding may manifest itself as the strong force.

  • The eight octahedral-face-centered color-bridgover-point dimples of an octahedrally-dimpled tri-toroid knot I guess are a good basis for SU(3)-type of logic. Lines passing through one toroid, close to a dimple, by one of its three creases and through the center, pass just as close to an opposing dimple, where intersection with a different toroid (color) of the three is assured. Two directions exactly through the same dimple and the center can mix all three torii (colors), 8 independent modes.

  • All three rings touch together in each of the eight face-centered dimples of the tri-toroid, implying the dimples are locii for color-exchange couplings. The low-energy-appearing regular equilateral octahedron lattice array avoids face-to-face dimples, while the space-filling lattice array of flattened octahdra maximizes face-to-face dimples.

  • The centers and corners of a body-centered cubic lattice carry the vertices of a space-filling lattice of flattened octahedra, where every octahedral vertex is shared with five neighbors. A face-centered cubic lattice carries the vertices of a regular lattice of equilateral octahedra, where every octahedral vertex is shared with one neighbor, which seems to be a lower-energy type of configuration.

  • Many depictions of three interlocked torii show eight three-sided dimples, each of which matches the orientation of a cube-corner in the cube-corner octhadron concept I mentioned. The toroid concept seems to have a low-energy character compared to the ribbon loop concept.

  • I've seen quark triplets drawn as three interlocking torii and as the three faces of a flattened Mobius ribbon loop. I guess mesons are like two interlocking torii and the two faces of a a flattened normal ribbon loop, going further with those ideas. The torii seem like orbitals stretched in time. I like to think three is a stable configuration because there are three dimensions, which seems to give a nod to the torii concept. Seems the fermionic aspect goes well with the flattened loop concept.
