Not really a prediction anymore, because it has already been verified, but still...
In an earlier version I (oktober/novermber 2019) I had not seen the data from 2019, quoted on the modeling page.
My model already predicted that (roughly) from 8 kpc onward the tangential speed would decrease slowly. (and it also explained why this is the case)
This feature is not being predicted by either the models that postulate 'dark matter', nor does it follow from MOND.
My model predicts this slope, and it predicts that in other milky ways, (with a similar structure) there will also be a slow but steady decrease
in tangential speed.
As for the empirical data I used to corroborate the validity of my model, I do not have any data concerning the placement of the
individual stars in relation to the disk. I predict that (in general) the stars with the highest velocity are closest to the eq-plane,
and the stars with the lowest velocity are furthest away from the eq-plane. As far as I can see, the other two theories don't contradict this.
However, in principle I could calculate the relationship between the height and the velocity.
Even if the other theories can make such a calculation, I am pretty sure they will not be the
same value. So here we can compare theories.
The calculations made here, can be made for other similar galaxys as well. I can predict the tangential velocity of the disk (and the way it diminishes with distance).
All that needs to be known is a) mass of the bulge b) mass of the disk c) half-distance of density.
As far as I know, only MOND makes similar predictions, but it seems that in some cases the value of a0 has to be altered slightly to obtain optimal results. Since a0 has to be a constant
this is not very satisfying.
