Light has been shifted in frequency at low power by heterodyning techniques in MIM diode structures. There's abundant literature on this.

The most important thing about this article is that it shows light can be frequency shifted by shock waves in a medium. Now apply this knowledge to the big picture - specifically cosmology and the cosmological red shift. The cosmological redshift is based on the assumption that primordal light was stretched (lowered in frequency) by the initial expansion of the universe (and remaining constant in velocity for all time, despite evidence to the contrary). Of course there's exceptions, but cosmologists are fully free to ignore contradictions in their theories. Now supposed instead of the big bang, the light simply passed through shocks waves in cold gases, giving local red and blue shifts. I know this goes against astrological, I mean cosmological science because it is reproducible in the laboratory and doesn't use dark matter or hidden energy or hidden dimensions or virtual particles or unmeasurable quantities but it is worth looking at by scientists.

That wouldn't give you the continuous emission spectrum we see in the CMBR. Where's the light coming from in the first place?

Ok Gary, you hooked me.
Does this imply that cosmology has just taken a big hit, and dimensionality a big boost?

Don't get me wrong, I'm not a scientist...Just interested.

The cosmological redshift

Good point. This one has potential.

Now apply this knowledge to the big picture - specifically cosmology and the cosmological red shift.

And latest studies seem to indicate that the "doppler" red shift is quantisized... that it jumps in values rather than a steady variation. This would tend to show that some thing like this shifting is caused by something other than mere distance.
