It deduces from a proposed graviton that v^4= G.M.Ho.c where M is the total barionic mass, and Ho is the Hubble constant

Tully-Fisher relation is not a method for measuring distances to spiral galaxies. The method is analyses of doppler shifting, and the Tully-Fisher relation is a relation between instrinsic brightness and the speed at which galaxies are rotating. Analyses of the doppler shifting allows determination of the radial velocity (speed at which it is rotating) and hence the Intrinsic brightness via the relation. This is then compared with the apparent magnitude to extrapolate a distance. This article needs completely re-wording in the immediate future. Jazzygm 16:38, 31 October 2006 (UTC)
Tully-Fisher relation links as a reference to a PowerPoint file whence I found a specific fact (the T â V^4 formula) that I didn't find in my other two sources. Because PPT is proprietary and Wikipedia is open-source / intended to be free and Free to all / has a significant non-Windows readership, I mentioned that the file works in OpenOffice.org. Is this statement POV, or fair notice for those without PowerPoint? --Geoffrey 02:16, 21 Apr 2004 (UTC)
There is more on the tully-fisher relation on scholarpeida [1], I don't really have much time, so could someone please write more about it using that article as a source? Pseudoanonymous ( talk) 07:34, 8 February 2009 (UTC)
Shouldn't the article mention dark matter as a possible explanation and not just MOND? Dmcq ( talk) 14:32, 5 January 2013 (UTC)
Overall the graph shown does not seem good evidence of a useful relationship since the slope is so poorly constrained ? Velocity scatter seems to have a range of about 3x ? graph has no explanation of 'h', or where the data comes from. Could we have a better/sourced graph ? The one at TFR by Tully is better described. - Rod57 ( talk) 13:08, 9 January 2017 (UTC)

There should be a disclaimer that clearly states the method may NOT be accurate, since it is based upon redshift to obtain the rotational velocity of galaxies. REDSHIFT is highly questionable as the basis of distance measurement. â Preceding unsigned comment added by 97.73.100.18 ( talk) 15:24, 22 June 2024 (UTC)
