The Baldwin effect! The propensity for spectral line width to get smaller with increasing redshift distance. This effect is present is every reshift survey that is not comparing apples and oranges. Why should spectral line widths get smaller with increasing distance? Line widths should not evolve, even if luminosity does. They don’t.

I know that you will all accuse me of trying to hijack this thread but this was one of the very first things that started me off on my theory (so tuff!). My equivalent love to Physics is photography and i knew that things further away are
always less distinct than things closer. In the seventies which I remember too well (60's as well if we are honest) there were always these pictures of redshifts (Kibbles book or something like that??) and the absorption lines were always more distinct the further away the galaxy!
So, what gets better the bigger the sample? Statistics thats what. I explain redshifts in terms of photons being constantly absorbed and re-emitted. I work it out in terms of probabilities. The further away the galaxy, the more the collisions the more distinct the effect.
Sorry about this but I will keep quiet now (maybe).
