My memory fails me, I have a distinct memory of reading an artice not to long ago, Thought it was NYTimes but did a search without results. The thesis was something to the effect that the expanding universe was steadily decreasing the overall electrical potential of the universe. This was having the effect of changing the interior distance of electron shells in all matter. The result, it was claimed, would skew the spectra we were observing and alter the frequencies in a way that is now explained solely by redshift. Presumably an electron falling down a shell -releasing a photon of fixed frequency-would issue a photon of uniformly shifted frequency if all those shells were altered on a macro level.
I won't even go so far as to say "it's just crazy enough to be true" but just want to know if anyone else recalls the article. (If not I solemnly swear I will never read another Science Fiction novel based on Velikovsky's work again)
Seems to me though that if it is true it might partly explain galaxies spinning too slowly, (since we measure their rotation by redshift)
