For perspective
Of all the cells in your body, all the enzymes, the molecules, the atoms, and fundamental particles; 99 percent is pure energy and of the volume 99 percent pure space.
Stevie - "do you have it in braille?"
Well if they have figured out mass is just energy I figure they have been working on time as well.
Mass is almost all a binding field
It isn't the particle that has the mass it is the field.
"quantum chromodynamics binding energy (QCD binding energy), gluon binding energy or chromodynamic binding energy is the energy binding quarks together into hadrons. It is the energy of the field of the strong force, which is mediated by gluons."
"Source of mass
Most of the mass of hadrons is actually QCD binding energy, through mass-energy equivalence. This phenomenon is related to chiral symmetry breaking. In the case of nucleons – protons and neutrons – QCD binding energy forms about 99% of the nucleon's mass. That is if assuming that the kinetic energy of the hadron's constituents, moving at near the speed of light, which contributes greatly to the hadron mass,[1] is part of QCD binding energy. For protons, the sum of the rest masses of the three valence quarks (two up quarks and one down quark) is approximately 9.4 MeV/c2, while the proton's total mass is about 938.3 MeV/c2. For neutrons, the sum of the rest masses of the three valence quarks (two down quarks and one up quark) is approximately 11.9 MeV/c2, while the neutron's total mass is about 939.6 MeV/c2. Considering that nearly all of the atom's mass is concentrated in the nucleons, this means that about 99% of the mass of everyday matter (baryonic matter) is, in fact, chromodynamic binding energy."
So most of the mass inside a nucleus is not matter it is energy.
Binding energy? A field? Or a Tensor? Or a Tensor Field?
How would that work? The particles spinning around each other very fast. why would they be spinning - deviation of axis. The energy is being used to keep the vortex open that the particles are spinning about that 'binds' them. That is what I picture.
Each force we understand has a different topology of 4D warping to create a force.
Good night
and keep in mind the universe we perceive is all based on broken symmetry (physics - look it up).
