Query: Curious numerical coincidence to the Pioneer anomaly   One noticed a numerical coincidence between the Pioneer spacecrafts
deceleration anomaly and $(\gamma-1)$, with $\gamma$ the Lorentz factor. The
match is not only for distances larger than 20 AU, but even for the observed
slop between 10 and 20 AU. Such numerical link may eventually lead to a
scientific hypothesis for future theoretical investigations.
