In this work we try a new approach for dealing with the discrepancy between observed galaxy rotation curves and theoretical predictions. This new approach does not involve any changes in the current fundamental laws of nature or the addition of dark halos. Rather, it is based on the following single assumption: the observed velocities presented in rotation curves are not given relative to the galaxies' local inertial frames. Another way of putting it down: fictitious forces, which arise in non-inertial frames, should be taken into account when constructing a theoretical rotation curve. It turns out that this single assumption is sufficient in order to establish a robust model for fitting rotation curves. Applying the new model on a sample of more than 30 galaxies provides very promising results.

Comment: Hello Roy and Tomer. Thanks for your fascinating paper. I wonder if the angular velocity you invoke relates to an idea developed by Kurt Godel from General Relativity but nowadays generally discarded: -
Matter everywhere rotates relative to the compass of inertia at twice the square root of pi times G times density.

I have obtained some interesting results by applying this to the entire universe and some mixed results by trying to apply it to galaxies.

Regards, Pete Carroll.
