Nature 477, 567-569 (29 September 2011), Gravitational redshift of galaxies in clusters as predicted by general relativity, Radoslaw Wojtak, Steen H. Hansen, Jens Hjorth: "According to the theory of general relativity, light emitted from galaxies moving in the gravitational potential well of galaxy clusters is expected to be redshifted proportionally to the difference in gravitational potential phi between the clusters and an observer, i.e., z_gr = (delta phi)/c^2, where c is the velocity of light in vacuum."
Einsteinians couldn't be more excited. Light loses frequency as it is escaping a gravitational field, just as predicted by Divine Albert, yes we all believe in relativity relativity relativity, and then the observer on the Earth gloriously measures this decreased frequency, yes we all believe in relativity relativity relativity. And even more excitingly, Divine Albert has predicted the same effect for the speed of light: Light loses speed as it is escaping a gravitational field, yes we all believe in relativity relativity relativity, and then the observer on the Earth gloriously measures this decreased speed, yes we all believe in relativity relativity relativity:
"Specifically, Einstein wrote in 1911 that the speed of light at a place with the gravitational potential phi would be c(1+phi/c^2), where c is the nominal speed of light in the absence of gravity. In geometrical units we define c=1, so Einstein's 1911 formula can be written simply as c'=1+phi. However, this formula for the speed of light (not to mention this whole approach to gravity) turned out to be incorrect, as Einstein realized during the years leading up to 1915 and the completion of the general theory. (...) ...we have c_r =1+2phi, which corresponds to Einstein's 1911 equation, except that we have a factor of 2 instead of 1 on the potential term."
"Einstein wrote this paper in 1911 in German. It predated the full formal development of general relativity by about four years. You can find an English translation of this paper in the Dover book 'The Principle of Relativity' beginning on page 99; you will find in section 3 of that paper Einstein's derivation of the variable speed of light in a gravitational potential, eqn (3). The result is: c'=c0(1+phi/c^2) where phi is the gravitational potential relative to the point where the speed of light co is measured......You can find a more sophisticated derivation later by Einstein (1955) from the full theory of general relativity in the weak field approximation....For the 1955 results but not in coordinates see page 93, eqn (6.28): c(r)=[1+2phi(r)/c^2]c. Namely the 1955 approximation shows a variation in km/sec twice as much as first predicted in 1911."
Wait wait... Slow light reaches the Earth? But this... No this is by no means a glorious confirmation of Divine Albert's Divine Theory... This is rather... contradicts special rela... Help! Help! Divine Einstein! Help! Yes we all believe in relativity, relativity, relativity!
No help is coming and in the end Einsteinians sing, in despair, "Lasciatemi morire":
Lasciatemi morire! Let me die! Let me die! And how can I possibly be consoled? In this cruel fate? In this great suffering? Let me die!
