   Classical radiation reaction was predicted in the early 20th century. I think that quantum theories for radiation reaction in with non-relativistic particles in weak fields has been around since the 1960s. The “hard” bit, that is currentl

   I do think there is a difference, but they are aspects of the same thing. One significant difference is that in the classical limit (ie taking the limit hbar -> 0) non-linear Compton scattering doesn’t produce energy loss for the elect

   Radiation reaction is related to Compton scattering. In Compton scattering, the interaction is between one electron and one photon producing one photon at a new energy, with the electron changing energy. Non-linear Compton is one electron

   I think a better way would be to make a mini magnetosphere around the space craft - most of the radiation that’s dangerous in space is high speed protons in the solar wind. By surrounding the space craft with a magnetised plasma you can m

   Good question! In radiation pressure the fact that the charges radiate energy isn’t included, it’s just the change in momentum due to to radiation being absorbed or reflected that produces a force. In radiation reaction the charges are acc

   I’d say that the main conclusion is the observation of a statistically significant (> 3 sigma) radiation reaction effect which is pretty consistent with both the classical model and the quantum model. The data “hints” that the quantum
