The Variable-c Cosmology as a Solution to Pioneer Anomaly

Cosmology and Nongalactic Astrophysics 2012-03-09 v2 General Relativity and Quantum Cosmology

Abstract

It is shown that the Pioneer anomaly is a natural consequence of variable speed of light cosmological models wherein the speed of light is assumed to be a power-law function of the scale factor (or cosmic time). In other words, the Pioneer anomaly can be regarded as a non-gravitational effect of the continuously decreasing speed of light which indicates itself as an anomalous light propagation time delay in local frames. This time delay is accordingly interpreted as an additional Doppler blue shift.
