I'm wondering something, when a body emits a photon, that photon has a specific energy (if it emits it at UV frequencies of 10^15 Hz, it's got a rather "low" energy. If it emits it at gamma frequencies of 10^23 Hz, it's got significantly more energy, but still rather "low" when we're talking about "massive" bodies emitting them (like anything the size of a bowling ball wouldn't even "feel" an "equal and opposite reaction").
The question is, is there an opposite force "felt" by the object when it emits a photon? I'm thinking no, because it's not a transfer of kinetic energy, its emitting already present energy.
Matter of fact, if it does make an equal and opposite reaction, then I think perpetual motion would exist from it, but I may be wrong there, I dunno...
Now I'm wondering because, if in theory something emitted a photon at 10^40 Hz, there is 16 million joules of energy in that photon (that's a lot, over 4 megawatt hours). Now, if that happened, if there was in fact an "equal and opposite" reaction being felt by that object, that object would *move*... fast...
