| May 16, 2022 at 4:36 | comment | added | Triatticus | @GedankenExperimentalist I believe then the wavelength becomes too long that it extends beyond our cosmological horizon. | |
| May 16, 2022 at 4:03 | comment | added | tobalt | perhaps when the energy density due to the photon becomes so high that electroweak symmetry is restored ? That would make electromagnetism obsolete. | |
