# The quantum vacuum as the origin of the speed of light

@article{Urban2013TheQV, title={The quantum vacuum as the origin of the speed of light}, author={Marcel Urban and François Couchot and Xavier Sarazin and Arache Djannati-Atai}, journal={The European Physical Journal D}, year={2013}, volume={67}, pages={1-6} }

We show that the vacuum permeability μ0 and permittivity ε0 may originate from the magnetization and the polarization of continuously appearing and disappearing fermion pairs. We then show that if we simply model the propagation of the photon in vacuum as a series of transient captures within these ephemeral pairs, we can derive a finite photon velocity. Requiring that this velocity is equal to the speed of light constrains our model of vacuum. Within this approach, the propagation of a photon…
