Influence of global cosmological expansion on NASA Pioneer Spacecraft local dynamics and kinematics

This, in my opinion, is more direct evidence for a finite hologram universe in the sense of P.C.W. Davies - Landauer et-al with the proviso that the world hologram is not our past particle horizon but our future dark energy event horizon.

Attempts to estimate the influence of global cosmological expansion on local systems are reviewed.

Here “local” is taken to mean that the sizes of the considered systems are much smaller than

cosmologically relevant scales. For example, such influences can affect orbital motions as well as

configurations of compact objects, like black holes. Also discussed are how measurements based on

the exchange of electromagnetic signals of distances, velocities, etc. of moving objects are influenced.

As an application, orders of magnitude of such effects are compared with the scale set by the

apparently anomalous acceleration of the Pioneer 10 and 11 spacecrafts, which is 10−9 m/s2. There is

no reason to believe that the latter is of cosmological origin. However, the general problem of gaining

a qualitative and quantitative understanding of how the cosmological dynamics influences local

systems remains challenging, with only partial clues being so far provided by exact solutions to the

field equations of general relativity.
