Nothing That Matters

Analysis of past Telemetry data of Voyager I and II show that they are about 8000 miles short of their calculated positions. What gives? Who is shortchanging Voyager Scientists? Scientists say that there are many possibilities:
1. There is a theory that in far out spaces, speed of light has a miniscule acceleration. Therefore the Voyager is in fact at correct position as per calculations, but the radio signals are covering that distance at a faster than uniform speed of light would warrant.
2. Newton's laws of gravity, duly modified for relativity, still require further modification.
3. Something else like action of dark matter in intervening space or curvature in space-time.
Gotcha! What gives, is that we loose our certainty of knowing the laws of physics. There is lot to be still learnt when scale of distance and time is too large or too small.
Oh! I have a better exlanation: Please read my following post Square The Cube
