Undergrad Expanding universe or tired light in a static universe?

Click For Summary
SUMMARY

The discussion centers around the concept of "tired light" as proposed by Lyndon Ashmore and its implications in the context of redshift and blueshift phenomena. Participants reference Ashmore's publication and a peer-reviewed paper by C.S. Chen, highlighting a contradiction regarding the presence of blue shift in Chen's findings. The consensus leans towards skepticism about the validity of the tired light theory, as it fails to align with observed Doppler shifts in wavelength. Overall, the dialogue underscores the scientific community's rejection of tired light as a credible explanation for redshift.

PREREQUISITES
  • Understanding of redshift and blueshift in astrophysics
  • Familiarity with the tired light theory
  • Knowledge of peer-reviewed scientific literature
  • Basic principles of Doppler effect in wave phenomena
NEXT STEPS
  • Research "Doppler effect in astrophysics" for a deeper understanding of wavelength shifts
  • Explore "tired light theory" critiques and alternative explanations for redshift
  • Read C.S. Chen's peer-reviewed paper for insights into the blue shift phenomenon
  • Investigate current astrophysical models that explain cosmic expansion
USEFUL FOR

Astronomers, astrophysics students, and researchers interested in cosmological theories and the debate surrounding redshift explanations.

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.

Here you can find his publication to download. I have bought and read the book: really interesting

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
If red shift is called "tired" then blue shift would have to be "wakeful". No wonder those ideas have no credence these days.

Tired light in a static universe predicts a constant shift in wavelength - while what is observed are doppler shifts, change in wavelength increasing with wavelength...
