Comments on the Quantum Vacuum and the Light Acceleration
AbstractThe recent observations on the far quasars absorption lines spectraand comparison of these lines with laboratory ones provide a frameworkfor explantation of these observations by considering a varying ﬁne struc-ture constant, over the cosmological time-scale. Also, there seems to be ananomalous acceleration in the Pioneer spacecraft 10/11 about 10 −10 m/s 2 .These matters lead Ranada to study the quantum vacuum to explain theseproblems by introducing a phenomenological model for the variation of α.In this manuscript we want to show that this model is not a quantummodel; it is a classical model that is only in accordance with mentionedobservations by adjusting some parameters and is not based on a funda-mental physical intuition. 1 Introduction The recent observations on the far quasars absorption lines spectra and com-parison with laboratory spectra show that these quasars are dimmer than thenearer ones [1]. The Webb group try to explain these observations by consid-ering a varying ﬁne structure constant [2]. The variation of the ﬁne structureconstant α = e
