Voyager 1 Spotted from Earth with radio antennas

[Phil]

Ah, always the referencing problem! I read about it a few years in a well-referenced book of essays on "unsolved scientific problems" (not just a sensationalist journalist's collection of thought-provoking nonsense). As always, my memory is unfortunately poorly archived and I will have to track down the book and the relevant references. I'll do my best.

There is (was?) a small NASA-funded research group trying to find 'other' causes for the Pioneer positional anomalies, but up to a few years ago, they had not been successful. The errors are very small, but then, the Pioneers and Voyagers are astronomically still on our doorstep.

The small error could be explained easily if Newton's theory of gravitation were to be modified with a small second-order component. The significance of this is that, if it were accepted that Newton's Law is merely a (very good) approximation, the need to find the the so-far undetectable "dark matter" in the Universe goes away - we don't need the extra mass to explain our astronomical observations. It astonishes me that the vast majority of scientists still insist that Newton's Law of Universal Gravitation is absolute and exact.
