The discussion centers on whether a photon qualifies as a real object, with participants noting that a gamma photon can produce electron-positron pairs, suggesting its reality. However, a key point raised is the contradiction in considering a photon a real object if it lacks an inertial frame where its velocity would equal zero. This leads to questions about the definition of a real object and whether it necessitates having an inertial frame. The conversation highlights the complexities of defining reality in the context of physics. Ultimately, the nature of photons challenges traditional concepts of real objects in physics.
