Modified Newtonian dynamics with inverse dissipation function as an alternative to dark matter and dark energy
This paper introduces an inverse dissipation function into the Newtonian Dynamics and studies the motion equations of the objects in the isolated gravitational system. It is found that at large scales it can simultaneously deduce the dynamical equation of cosmic expansion similar to the Adiabatic Cold Dark Matter (ACDM) model and yield the flat rotation curves for spiral galaxy. Different from the usual dark matter models, the derived flat rotation curve is the result of time accumulation rather than the direct action of mechanics. And the Tully-Fisher relationship is also discussed. It is found that the empirical constant a 0 in the Modified Newtonian Dynamics (MOND) model proposed by Milgrom and the form of the function μ are shown a clear corresponding physical significance in the model of this paper.
