The difference is just in how you lay down the coordinate system on the space. If you use coordinates that are expanding with the stars, you'd say space stretches. If you use cooordinates that maintain a fixed distance from some reference point, then the stars are moving with respect to those coordinates. GR tells us that the 'real' physics is the coordinate invariant stuff, and the two ways of thinking about it give the same redshift result.

I'll go try that out on my PC. Added the link to the story and, thanks to all Oli's other plugs, this calls for a separate item. Sorry I just deleted the link from your comment; those are still screwing up the template. One of the MANY things that will be fixed when we move the official site over to our in-development CDM 2.0 in WordPress! Can't wait! Peter Thanks, Afro. I’ll go try that out on my PC.
