Discussion Overview

The discussion revolves around the implications of μ¨ based cosmologies on galaxy evolution, particularly in light of recent observations from the James Webb Space Telescope (JWST). Participants explore the divergence between high and low redshift observations and introduce speculative concepts such as the Primordial Bovine Herd (PBH) and its relation to dark energy.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants present findings from a study that suggests μ¨ based cosmologies align with JWST observations of massive galaxies at high redshifts, while diverging from low redshift cosmic star formation rates.
  • One participant humorously critiques the notion of a "Primordial Bovine Herd" as a source of dark matter/energy, implying skepticism about the validity of such claims.
  • Several participants share links to additional arXiv papers, indicating a broader interest in related topics, though the relevance to the main discussion is not explicitly stated.
  • Another participant references an older paper as an example of humorous or non-serious contributions to the field, suggesting a light-hearted tone in parts of the discussion.
  • There is a playful exchange about the nature of the PBH concept, with one participant suggesting a humorous take on dark matter.
  • Participants signal a return to serious discussion after a light-hearted interlude, indicating a mix of humor and serious inquiry in the thread.

Areas of Agreement / Disagreement

The discussion contains a mix of serious exploration of μ¨ based cosmologies and humorous commentary. There is no clear consensus on the validity or implications of the PBH concept, and skepticism is expressed regarding the more whimsical aspects of the discussion.

Contextual Notes

The discussion includes speculative ideas that lack detailed mechanisms or empirical support, particularly regarding the decay process of the proposed PBH and its implications for dark energy.

We present the first study of galaxy evolution in μ¨ based cosmologies. We find that recent JWST observations of massive galaxies at extremely high redshifts are consistent with such a cosmology. However, the low redshift Universe is entirely divergent from the μ¨ cosmic star formation rate density. We thus propose that our Universe was at one point dominated by a Primordial Bovine Herd (PBH) which later decayed producing dark energy. Note that we do not detail the mechanisms by which this decay process takes place. Despite its vanishingly small probability for existence, a μ¨ based cosmological model marries the disparate findings in the high and low redshift Universe.

N.B. μ¨ would be pronounced approximately as "moo". The PBH acronym is a reference to "Primordial Black Holes" which have the same acronym.

...and I hope no one would be so rude as to suggest that the immense volume of dark matter/energy spontaneously created on the arxiv every day has its origins in a primordial bovine herd. :oldruck:

And a steaming pile of dark(ish) matter?

And now we have had our April Fools fun (aka April 1st, 2023) we return to our regularly schedule posting of peer reviewed non April-Fools-Joke-articles.

We leave you with a simple message: Klatu Barada Nikto!
