#608495 — Galactic Precession would explain Asymmetrical Rotation Curves

The construction of Galactic Rotation Curves
is done by averaging data from
opposite sides of the disc. The curves
from opposite sides are asymmetric. Why?

This would be the observation if
galaxies were precessing, as well as
rotating.

What else could cause this?

Asymmetric distribution of matter in the galaxy, of course.

No, it's not.  We'd see, for galaxies seen face on, one edge redshifted
relative to the center, and the other edge blueshifted. We don't see that,
so precessing can be ruled out (as if all the other reasons weren't 
enough).

Why are you still so obsessed with retarded precessing spinny things?

Asymmetric distribution of matter in the galaxy.

They use redshift to get the rotation curves.
For any particular disc, measurement 
of opposite sides yields asymmetric curves,
which- when combined- give the general
curve for the galaxy.
If there were more matter on one side
than the other, there would:
a. have to be perfect ANTISYMMETRY
b. be places where the two curves are
    very similar both to each other and to the
    general curve.

Quite true.  But we still don't see face-on galaxies with one edge relatively
blueshifted (therefore approaching us) and the other edge receding (therefore
moving away). Thus no retarded precession.

What we do see is more edge-on galaxies with those characteristics. One edge
approaches and the other moves away. Thus we can see the galaxy is rotating.
And we see they aren't quite symmetric, indicating an uneven distribution of
mass.

So, you think galactic discs are
"uniformly lopsided"?
Odd will love that concept- very much
like an "unstructured structure ". :)

Not all spiral galaxies are "uniformly lopsided", but many are...

So Michael is saying
that face-on galaxies have been
analyzed in this same way
and found to be NOT red shifted
on any particular side?
Or, because they are lopsided,
they WOULD be?
Or what

Correct.

Since the rotation is perpendicular to our line of sight, we would not see
redshift or blueshift from the rotation.  If there was such thing as
precession, we'd see one side redshifted and the other blueshifted.  But
we don't.  So retarded precessing galaxies are only part of your dreams
(or hallucinations), not reality.

there are all sorts of anamolous shifts,
apparently having nothing to do with velocity per se;
see Halton arP etc.  of course, a)
there is no absolute or pascalian vacuum, and b)

I still think that John has confused his kooky thinking with the observed M-sigma relationship between galactic smbh and the galactic hub.

I'm trying to give him the benefit of the doubt here.
