Title: Relativistic Insight Into Dynamic Structure of Spiral Galaxies: Gravity, Fluid-lorentz-force, and Dark Matter Effect
Abstarct: This is a novel approach based on general relativity and applied to the galactic dark-matter effect observed
in rotating galaxies. Dynamical unfolding within galaxies has been investigated to find a possible physical
mechanism producing the flat rotation curve in outer parts of galaxies. Dynamical structures are studied for
galaxies surrounded with abundant gas clouds, based on fluid dynamics extended to the relativistic theory.
The present results show an excellent match with the observed finding by McGaugh, Lelli & Schombert
(2016). This matching implies that the present approach has captured an essential aspect of the galactic darkmatter
effect. Concerning the physical mechanism, this study implies that the orbital hyper-speed of 40 ∼
200 km/sec observed in the halos is maintained by a new force of fluid-Lorentz-force working in galactic
space. Existence of the fluid-Lorentz-force is not contradicting with the concept of the theory of general
relativity.
