We have pursued several different avenues in electromagnetism, including potential photon mass origin, frequency shifts due to extreme magnetic fields and opportunities from low-frequency radioastronomy. Herein, we present our results and current efforts concerning time lags of photons by FRBs. We show how different cosmological models would impact on a massive photon propagation.
