   Propagation and Wave Characteristics
   In free space, electromagnetic waves travel at the speed of light, $c$. The absence of dissipative media means that such propagation is lossless, provided the wave frequency does not approach the theoretical "Chroniton Resonance Band" (approximately $4.8 \times 10^{35} \ \text{Hz}$), where vacuum polarization is predicted to become highly non-linear 4.
