Supernova Distance Debate: New Evidence from Astrophysics Research by H. Arp"

AI Thread Summary
The discussion centers on a recent supernova that reportedly outshines typical supernovae by a factor of at least 100, located in a minor galaxy within the Perseus Cluster. H. Arp presents evidence suggesting that this supernova may be significantly closer than its redshift distance indicates, proposing a tenfold reduction in distance. The implications of this finding challenge existing astrophysical models and raise questions about the accuracy of distance measurements in cosmology. Participants express curiosity about the ongoing research and the potential impact of Arp's conclusions on the understanding of supernovae and cosmic distances. The conversation highlights the need for further examination of Arp's claims and the relevance of his work in contemporary astrophysics.

How certain is the distance to the most luminous supernova?
Authors: H. Arp
Comments: 5 pages, 3 figures
Subjects: Astrophysics (astro-ph)
A recent supernova has been reported as exceeding ``the light output of an ordinary supernova by at least two orders of magnitude''. It is noted that it falls in a minor galaxy in the Perseus Cluster. Some evidence indicating a ten times closer distance for the Perseus Cluster than its redshift distance is discussed here.

Is anyone listening to HA?

I wrote here about another interpretation.
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
