Do they just store them somewhere? Do the photons get formed from energy?
In: Physics
If you believe fields have physical reality, then there are no particles per se – there are fields, and excitations in those fields *are* particles. The electron field and photon field affect each other, and one of the things they can do is allow the electron excitation lose energy while a photon excitation is formed in the photon field.
If you want to talk purely in particle terms, then the photon is just plucked from the vacuum. We don’t really need an underlying physical model for *where* it comes from to make accurate physical predictions.
