What Medium Does Light Travel Through in Space?

I'm confused

My goof - wrong paper. Now fixed. The correct paper (by Demystifier who often posts here) is:

Sorry

Okay, I'll read what you referred to, but what about the Casimir effect, the Lamb shift, spontaneous emission, etc.? Surely these are real, yes?

For spontaneous emission, the issue is that, according to ordinary QM, the energy levels are stationary and remain the same. The solution is that, due to the electric field of electrons, they are coupled to the Quantum EM field permeating all space. This coupling means they are not stationary.

Thanks
