I like Robin's approach -- perhaps there's an intrinsic process driving the sun's 11 year cycle, and it has influenced where the planets formed and how they orbit in relation to one another. Perhaps there is a very low frequency acoustic resonance at work, like the ringing of a slow bell. As a layperson watching astrophysics from a distance, I have not yet been persuaded of the need for dark matter or energy. It has always felt a little bit like an ad hoc remedy to make other assumptions work. I'm sure if one is more familiar with all of the pieces and how they fit together, it is harder to ignore these two hypotheses (dark matter and dark energy). Eric
