Discussion Overview

The discussion revolves around the plasma-redshift cosmology and its implications for interpreting supernova data, particularly the SNLS data. Participants explore the validity of this cosmological model in contrast to established theories, including the big bang cosmology.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants note that the plasma-redshift cosmology claims to match the predictions of the magnitude-redshift relation for type Ia supernovae, suggesting no cosmic time dilation and challenging the big bang model.
  • Others express skepticism about the credibility of the paper presented, questioning its acceptance in reputable journals and the validity of the claims made by the author.
  • There are comments regarding the author's previous contributions to the forum and the perceived lack of novelty and development in the plasma cosmology idea.
  • Some participants discuss the recent changes in arXiv's submission policies, suggesting a more lenient approach towards speculative ideas, while also emphasizing the need for higher standards for such submissions.

Areas of Agreement / Disagreement

Participants generally disagree on the validity and acceptance of the plasma-redshift cosmology, with some supporting its claims and others challenging its credibility and the author's ability to publish the work.

Contextual Notes

There are unresolved questions regarding the author's claims and the implications for established astrophysical theories, as well as the standards for publication in scientific journals.

We have previously shown that the type Ia supernovae data by Riess et al. match the prediction of the magnitude-redshift relation in the plasma-redshift cosmology. In this article, we also show that the recent SNLS data, which have a slightly narrower distribution as reported by Astier et al. in 2005, match the predictions of the plasma-redshift cosmology. The standard deviation of the SNLS-magnitude from the predicted curve is only about 0.14. The data indicate that there is no cosmic time dilation. The big-bang cosmology therefore appears false. The plasma redshift, which follows from exact evaluation of photons interaction with hot sparse electron plasma, leads to a quasi-static, infinite, and everlasting universe. It does not need big bang, dark energy, or dark matter for describing the observations. It predicts intrinsic redshifts of galaxies consistent with what is observed. The Hubble constant that best fits the SNLS data is about 63 km per sec per Mpc. This corresponds to an average electron density of about 0.0002 per cubic centimeter in intergalactic space. This density together with the plasma redshift heating to an average plasma temperature in intergalactic space of about 3 million K explains the observed isotropic cosmic microwave background (CMB) and the cosmic X-ray background.

I hate to tell you this, but the 2006 APS April meeting hasn't occurred yet.

I know you copied that off the arxiv page, but (i) one doesn't present a "paper" at either the March or April meeting, so what this "paper" here is supposed to be is a mystery (ii) there are no conference proceedings at those meetings (iii) this person has a lot of explaining to do on where he intends to submit this for publication.

Zz.
 
As ZZ already implied, it's unlikely this would accepted to respectable journal. Unfortunately, there's only so much arXiv can do to filter out crackpot submissions.
 
Well hey, i can not pick (all) the good ones.:redface:
 
Ari has been 'on' PF's astronomy section before; his plasma cosmology idea (I doubt that it's sufficiently well developed to call it a model yet) is not entirely novel. The amount of 'unexplaining' he will have to do is huge - just about all of extragalactic astrophysics (and much of stellar astrophysics no doubt too).

Let's wait and see if he can even get this published.
 
Arxiv appears to have lightened up on what/who has been granted preprint priveleges over the past few months. Eric Lerner and Halton Arp, to name a couple, have graced the archive recently after rather lengthy absences. A kinder, gentler Arxiv? Some of the 'mavericks' in theoretical circles mounted a campaign against Arxiv 'censorship' last year which garnered some sympathy. And I think that is a good move. It is not good science to exclude ideas not decisively refuted - albeit I think speculative papers should be held to a higher standard than mainstream material [e.g, make reasonably falsifiable predictions]. Besides, it's great fun for us unwashed masses to have stuff upon which even we can inflict puncture wounds.
