SUMMARY
Quarks are indeed smaller than electrons, as established in particle physics. When an electron transitions from a higher to a lower energy level, it emits a photon, not a quark. Quarks are fundamental constituents of protons and neutrons, while photons serve as force carriers in electromagnetic interactions. The discussion clarifies that quarks are real particles, whereas virtual particles, such as virtual photons, are used to describe interactions in quantum field theory.
