Abstract

If an observational effect induces an apparent spatial compression of galaxies, it may account for the discrepancies in their observed orbital speeds. This study investigates whether the flat rotation curve arise from such an observational effect rather than requiring dark matter or modifications to gravity. Using an inverse problem approach, we demonstrate that Newtonian dynamics remain consistent with observed rotation curves when incorporating a radially dependent space scale factor that maps true spatial dimensions to observed ones. Analyzing 175 galaxies from the SPARC dataset, we find that the intrinsic curvature associated with this apparent compression exhibits a strong correlation with the Ricci curvature derived from the baryonic mass distribution.

  Publication Timeline

As of June 2025, this work has been submitted to a few journals and has received the following feedback so far:

  • Editor-in-Chief, Journal of Computational Physics: "Thank you for your submission. I have carefully examined it, but I regret to inform you that I do not believe that it is suitable for the Journal of Computational Physics. The Journal generally publishes articles on new or improved numerical methods, with examples showing the utility of the proposed approach. We have not published much in the subject area of your manuscript recently and the manuscript is therefore unlikely to reach its target audience in the Journal. Instead of going through the full review cycle, which is likely to take several months and probably results in the rejection of your manuscript, I have decided to return it to you so you can submit it to a more suitable journal. Please note that my decision in no way reflects a judgment on my part about the quality of your manuscript, only its suitability for the Journal of Computational Physics. I am sorry I cannot accept your manuscript in the Journal of Computational Physics, and I hope your work will be published in an appropriate journal where it will reach the audience it deserves. "
  • Scientific Handling Editor, Physics of the Dark Universe: "Although the problems being addressed are potentially of interest to our readership, your manuscript does not meet the required quality standards to be considered for publication."
  • Editor, Astronomy and Computing: "While your results are of potential interest, the topic of your manuscript falls outside of the scope of this journal. For an overview of the Aims & Scope, please have a look at the journals’ homepage. We hope you will consider the journal for publication of future studies within the scope."
