SUMMARY
The forum discussion centers on the relationship between electrostatic fields and photons within the framework of Quantum Electrodynamics (QED). Participants assert that electrostatic fields cannot be accurately described as being composed of photons, whether real or virtual. The conversation highlights the complexities of modeling static charges and electromagnetic fields, emphasizing that the Coulomb field is not represented by a single photon but rather through a series of soft-photon ladder diagrams. Key references include Weinberg's "Quantum Theory of Fields," which provides a comprehensive treatment of these concepts.
