John Archibald Wheeler and Richard Phillips Feynman propose that radiation arises from the interaction with an absorber, not directly from the accelerated charge. They argue that the traditional concept of action at a distance, while mathematically consistent, fails to explain the mechanism of radiation due to difficulties in accounting for the radiative reaction force. The force of radiative reaction is a result of the interaction between the source and the absorber, with the absorber's half-advanced fields contributing to the force experienced by the source. This mechanism explains the observed damping force on an accelerated charge, which is simultaneous with the acceleration. The absorber's response leads to a field that combines with the source's field to produce the full retarded field, consistent with experimental observations. The authors derive the radiative reaction force using different approaches, showing that it arises from the interaction between the source and the absorber. The force is shown to be proportional to the acceleration and its time derivative, and is consistent with both classical and relativistic treatments. The absorber theory provides a unified explanation for the radiative reaction, reconciling the apparent contradiction between the retarded and advanced fields. The results demonstrate that the radiative reaction force is a consequence of the absorber's response, not the direct action of the charge on itself. The theory is consistent with the observed behavior of radiation and provides a framework for understanding the interaction between charged particles and the absorber in the context of field theory.John Archibald Wheeler and Richard Phillips Feynman propose that radiation arises from the interaction with an absorber, not directly from the accelerated charge.
