Ok, so here's a question. The energy of say photons is frame-dependent. Photons are blue-shifted or red-shifted depending on my velocity towards or away from the source. However, what happens when I apply this to pair-production? For example, if my photons are energetic enough, they may create a positron-electron pair. If my photons are NOT energetic enough they don't create the pair.
However, since the energy is frame-dependent, it would seem to suggest that whether a pair is created or not is frame-dependent. The existence of particles, however, should not be frame dependent. Paradox! Obviously my logic is faulty somewhere.
Please resolve this for me. Thanks. =)
