SUMMARY

The discussion centers on the potential for discovering new physics through the re-evaluation of cosmic redshifts, as highlighted in a recent article titled "LCDM Tensions: Localising Missing Physics Through Consistency Checks" (February 2024). The conversation references an earlier paper from 2011, "The New Physics of Cosmic Redshift," which suggests limited new insights from redshift analysis. Participants express skepticism about the novelty of findings in this area, yet acknowledge the passage of time since the earlier study, indicating that new methodologies or data could yield different results.

PREREQUISITES
  • Understanding of cosmic redshift and its implications in astrophysics.
  • Familiarity with the Lambda Cold Dark Matter (LCDM) model.
  • Knowledge of scientific literature review and analysis techniques.
  • Basic grasp of physics concepts related to cosmology.
NEXT STEPS
  • Research the latest findings in cosmic redshift analysis and their implications for physics.
  • Explore methodologies used in the 2024 paper on LCDM tensions.
  • Review the 2011 paper "The New Physics of Cosmic Redshift" for historical context.
  • Investigate advancements in observational techniques for measuring redshifts.
USEFUL FOR

Astronomers, physicists, and researchers in cosmology who are interested in the implications of redshift analysis and the search for new physics in the universe.

(arxiv, Feb, 2024) LCDM Tensions: Localising Missing Physics Through Consistency Checks.

So, another article which - to me - looks intriguing but sadly passes pretty far over my head. I'm always a little sceptic about articles whose authors start out with a poetry quote - or, as is "often" the case - a Doglas Adams quote.

It seems to make a case for new physics to be found re-evaluating redshifts.

I then found this old paper: (arxiv, 2011) The New Physics of Cosmic Redshift which seems to say that there's nothing, or at least not much, new knowledge to be found there, but, ofcourse a lot of time has passed between the two.

I guess I can't expect anyone to read through all this just to give me their opinion, so I'll settle for an answer to this "simple" question:

Is it conceivable that there's new physics to be found hiding in the re-analysis of the redshifts of the objects out there?

I'll understand if my question is too naive or vague to merit a serious answer (much less one I can actually understand), It just seemed to me that they're talking about a relatively "simple" approach.

Regards.
