Are there issues with Conformal Gravity as a DM solution?

[QUOTE="strangerep, post: 6108257, member: 70760"] Did you perhaps miss the sign on the "cm" exponent? ##\kappa## has dimensions of inverse area, not area. Also, compare ##\kappa = 9.54 \times 10^{-54}## vs ##\Lambda \approx 1.6 \times 10^{-56}## (both in cm##^{-2}##). [B]Edit:[/B] It might be a while before I feel confident enough to post the next installment. I've realized I need to understand the papers of McGaugh et al quite thoroughly in order to relate their work on the generic, phenomenological RAR (Radial Acceleration Relation) with the somewhat different Conformal Gravity formulas of Mannheim, O'Brien, et al. See: [URL]https://arxiv.org/abs/1609.05917[/URL] and [URL]https://arxiv.org/abs/1610.08981[/URL] [/QUOTE]
