stefan r said:He sites a peer reviewed paper by C.S. Chen. I do not have access to the full article. The abstract clearly says "blue shift" and "red shift". Lyndon Ashmore's https://www.researchgate.net/publication/228730621_Intrinsic_Plasma_Redshifts_Now_Reproduced_In_The_Laboratory-a_Discussion_in_Terms_of_New_Tired_Light (page 2, left column, second paragraph) claims Chen's research shows no blue shift. That looks like a contradiction.
Well if he is writing about "tired light", I wouldn't take his writings too seriously because tired light is not a correct idea/theoryEnnio said:Here you can find his publication to download. I have bought and read the book: really interesting

If red shift is called "tired" then blue shift would have to be "wakeful". No wonder those ideas have no credence these days.davenn said:Well if he is writing about "tired light", I wouldn't take his writings too seriously because tired light is not a correct idea/theory
The expanding universe theory, also known as the Big Bang theory, states that the universe began as a single point and has been expanding ever since. This expansion is supported by observations of the redshift of galaxies, which indicates that they are moving away from each other.
The tired light theory suggests that the redshift of light from distant galaxies is not due to their motion away from us, but instead is caused by the light losing energy as it travels through space. This would imply that the universe is not expanding and is in a static state.
We know that the universe is expanding because of the observations of the redshift of galaxies. This redshift is consistent with the idea that the galaxies are moving away from us and from each other. Additionally, the cosmic microwave background radiation, which is leftover radiation from the Big Bang, also supports the expanding universe theory.
The tired light theory has been largely discredited by modern observational evidence. The redshift of galaxies is not the only piece of evidence used to support the expanding universe theory. Other evidence, such as the abundance of light elements in the universe and the large-scale structure of the universe, also point towards an expanding universe.
At this time, there is no definitive way to prove which theory is correct. However, the expanding universe theory is currently the most widely accepted and supported by observational evidence. Future advancements in technology and observational techniques may provide more insight into the nature of the universe and help us better understand which theory is correct.
