SUMMARY

Quantum Electrodynamics (QED) explains the interaction of photons with electrons, establishing the foundation for understanding the electromagnetic field. The discussion highlights the role of virtual photons in mediating electromagnetic interactions and raises questions about their implications for gravitational forces. While many theorists propose that virtual gravitons are responsible for gravity, the absence of empirical evidence for gravitons complicates this theory. The uncertainty surrounding the second quantization of the gravitational field further emphasizes the complexities of these fundamental forces.

Quantum Electro Dynamics, the quantum theory of the photon, describes the photons interaction with electrons and this is what I beleived created the electromagnetic field. However recently I've heard a disscusion that virtual photons and their interaction with electrons and the polarization of virtual particles conveys electromagnetism, in fact it was said that virtual particles communicate all the forces through spacetime, but this doesn't sound right in gravity's case. I want to know if this is true, and if anyone can shed some light on this topic, thanks.

Many people believe that the gravitational force is due to the exchange of virtual gravitons, but gravitons have never been found. So far, we don't even know whether the gravitational field admits second quantization.
