Local Scale Covariance and Its Radical Implications for Cosmology

Round 1

Reviewer 1 Report

In this paper, the author proposes a new form of scale covariance based on classical electrodynamics which is claimed to have implications for cosmology. The idea is interesting, and the paper may be considered for publication if the following points are addressed:

1. The idea of scale covariance has been around for some time now, and some history of scale covariant theories should be provided, including that of Canuto et al [e.g. PRD 16(1977)1643].
2. How does the present theory improve on previous scale covariant theories/models?
3. A theory should provide some observational tests which could verify it. What are the observational predictions of the present theory, or it it another theoretical model? How do the predictions of this theory differ from the standard LambaCDM model?

 

Author Response

In response to point #:

1. I've extended the introduction to include reference to previous work stemming from Weyl invariance.
2.  In the above discussion I further explain why my approach only superficially resembles the former and why IMHO it is conceptually deeper. 
3.  At the end of the second paragraph of the introduction I have added a note regarding novel predictions. Those indeed appear in fig.1 (see caption) despite my proposal, in its present form, clearly being only a skeleton for a comprehensive, scale covariant cosmological model. 

Reviewer 2 Report

I can not recommend this paper for publication in Galaxy as it has massive overlapping the following self manuscript:

 

Dark matter as variations in the electromagnetic zero-point-field
induced by baryonic matter

Author Response

My mentioned reference indeed appeared in tandem with the current submission as part of one massive paper, which was later split in order to ease its digestion. Hence the unavoidable partial overlap in background sections (albeit with different emphasis). Nevertheless, scale covariance plays almost no role in my previous paper, which further does not deal with cosmology. The current submission greatly extends and completes the picture of the former, and I consider it advantageous to have keep it as self-contained as possible.    

Reviewer 3 Report

In this paper, the author has studied "Scale covariance and its radical implications for cosmology". My comments are following:

1. The author have written the introduction, main body of the paper and the conclusion in an elaborative and appropriate fashion.
2. Computations and results presented in this paper are technically correct and all the interpretations of the results are presented correctly.  
3. The only flaw I have found in the reference list. The author needs to cite a sufficient number of references in this literature. There are many important citations the author did not consider in the present version. The reference list needs to be rigorously updated.

Once the reference list will be thoroughly updated I will give my final decision on this manuscript.

Author Response

I have extended the introduction to include comparisons with previous relevant work on scale covariance.

Round 2

Reviewer 2 Report

Author should upload the revised and correct version.

Reviewer 3 Report

The author has addressed the points that I have raised in my last report. I strongly recommend the publication of the present version of the paper.

Round 3

Reviewer 2 Report

The manuscript may be accepted for publication in its present form.
