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… 
Dispersive property of the quantum vacuum and the speed of light
We want to study the influence of the quantum vacuum on light propagation. At first, by working in the standard linear quantum theory of the electromagnetic fields, it is shown that the electric
Intrinsic measurement errors for the speed of light in vacuum
The speed of light in vacuum, one of the most important and precisely measured natural constants, is fixed by convention to c=299792458 m s−1. Advanced theories predict possible deviations from this
How vacuum fluctuations determine the properties of the vacuum
Particle-antiparticle pairs are predicted by quantum field theory to appear as vacuum fluctuations. The model of the vacuum used here is postulated to have the following properties: To minimize the
Reply to the Comment on: The quantum vacuum as the origin of the speed of light
We reply to the comment by Schiller on our paper “The quantum vacuum as the origin of the speed of light” [M. Urban et al., Eur. Phys. J. D 67, 58 (2013)]. We further detail our model and explain why
Comment on: The quantum vacuum as the origin of the speed of light
In a recent paper, Urban et al. [Eur. Phys. J. D 67, 58 (2013)] propose a model of the vacuum that predicts a fluctuating speed of light. Here, it is pointed out that under certain assumptions, past
Polarization of Vacuum Fluctuations: Source of the Vacuum Permittivity and Speed of Light
There are two types of fluctuations in the quantum vacuum: type 1 vacuum fluctuations are on shell and can interact with matter in specific, limited ways that have observable consequences; type 2
On the carrier of inertia
A change in momentum will inevitably perturb the all-embracing vacuum, whose reaction we understand as inertia. Since the vacuum’s physical properties relate to light, we propose that the vacuum
The Electron as a Composition of Two Vacuum Polarization Confined Photons
In a previous paper “A Physical Electron-Positron Model”[1] an electron model was developed in a geometrical algebra (GA) construct developed by Doran [2] The model shows the mathematical
Physical mechanisms underpinning the vacuum permittivity
Debate about the emptiness of the space goes back to the prehistory of science and is epitomized by the Aristotelian horror vacui, which can be seen as the precursor of the ether, whose modern


Quantum-Gravitational Diffusion and Stochastic Fluctuations in the Velocity of Light
We argue that quantum-gravitational fluctuations in the space-time background give the vacuum non-trivial optical properties that include diffusion and consequent uncertainties in the arrival times
A limit on the variation of the speed of light arising from quantum gravity effects
The detection of emission up to ∼31 GeV from the distant and short GRB, and no evidence for the violation of Lorentz invariance is found, which disfavour quantum-gravity theories in which the quantum nature of space–time on a very small scale linearly alters the speed of light.
Our high-time-resolution observations reveal that individual main pulses from the Crab pulsar contain one or more short-lived microbursts. Both the energy and duration of bursts measured above 1 GHz

Interferometers as probes of Planckian quantum geometry
A theory of position of massive bodies is proposed that results in an observable quantum behavior of geometry at the Planck scale, ${t}_{P}$. Departures from classical world lines in flat spacetime
