Description
A field flux picture with generalized Integral Gauss’s law of gravity is proposed for an alternative solution for mass discrepancy problem of disk galaxies. The flat rotation curve of disk galaxies is modeled by a cylindrical distribution of the gravitational field flux along the disk surface and the radius dependence of the field strength becomes 1/r, instead of Newtonian 1/r^2.
Below a critical field ~10^(−10) 𝑁/𝐾𝑔(which is considered as a minimum area density for flux lines to maintain spherical distribution, the gravitational flux distribution turns from spherical to cylindrical. The Tully-Fisher relation can be obtained from this transition.
From radial acceleration relation of disk galaxies, with or without bulge, a structural-dynamical correlation can be explained by a flux distribution transition across the critical field.
In addition, the Faber-Jackson relation of non-disk galaxies can be considered as a transition off the spherical distribution of the gravitational field flux. It is suggested that at the same of finding dark matter particles, physicists may also consider finding some non-Newtonian gravity as a low field limit of the theories of gravity.
