Default Galaxies without dark matter halos?

Your theory of the origin of galactic rotation curves fails to account for
recent measurements of the dark matter haloes by means of weak

gravitational
lensing.


I belive you've gone circular, here. Without "dark matter" the big bang's
current incarnation is dead. The "measurement" of distance used in those
"lensing" studies assumes the big bang (pure doppler for the Hubble
constant). Hence your mass estimates are worthless for the purpose of
discriminating between dark matter and non-dark matter.

[Mod. note: of course, the distance-redshift conversion for distant
objects is not `pure Doppler', but it does assume that the universe is
expanding -- mjh.]
