Redshift Caused by Tired Light (Nov, 1932)

To think, I’d always believed that redshift was caused by the doppler effect. How silly of me. Actually the light just gets really tired! (You would too if you’d traveled for 13 billion light years without a single vacation day). And of course blueshift occurs when the light is really happy or excited, like when it wins a race against… well anything really.

According to Wikipedia redshift was first used to measure the velocity of a star moving away from the Earth in 1868 so they really don’t have an excuse for not getting the memo. My only guess is that they couldn’t accept the fact that practically everything in the Universe is moving away from us and that the farther away it is, the faster it’s going. This of course leads to crazy ideas like the big bang.

Light Gets Tired and Turns Red
THAT light rays get tired as they travel for millions of years through space, fritter away a little of themselves century by century and end by changing color so that rays which started as blue ones may finish by becoming red is suggested by scientists. Astronomers have discovered that light rays coming to the earth from the most distant nebulae actually show what is called the “red shift,” which means the light from these nebulae is shifted a little toward the red end of the spectrum. What may be happening is that each tiny bit of each light ray may lose a small fraction of its substance as it moves through space.

  1. [...] While some people might try to tell you that light is subject to the doppler effect, the authors of this article from the November 1932 issue of Modern Mechanix magazine know otherwise. The reality is, after travelling for centuries and centuries to reach earth, the light is tired, and slows down as a result. My theory is the light just wants to stop and smell the roses, seeing how Earth is the only planet around that has roses. Now I can’t confirm that Earth is the only nearby planet with roses, but I’ve got a pretty strong conviction on this. [...]
