There appears to be a lot of evidence that gas flows outward in Galaxies. I've been trying to parse through the available data and am unable to get a clear answer to this question: is there any evidence for an average flow of stellar material in our galaxy? That is, do we know if stars are falling in, falling out, in a perfectly stable orbit (or do we just not have enough data yet)?
