The Structuring Force of Galaxies

Authors: Jin He
Comments: 45 pages (the final 28 pages are c++ program source file)

The concept of rational structure was suggested in 2000. A flat material distribution is called the rational structure if there exists a special net of orthogonal curves on the plane, and the ratio of mass density at one side of a curve (from the net) to the one at the other side is constant along the curve. Such curve is called a proportion curve. Such net of curves is called an orthogonal net of proportion curves. Eleven years have passed and a rational sufficient condition for given material distribution is finally obtained. This completes the mathematical basis for the study of rational structure and its galaxy application. People can fit the stellar distribution of a barred spiral galaxy with exponential disk and dual-hand structure by varying their parameter values. If the conjecture is proved that barred galaxies satisfy a rational suffcient condition then the assumption of galaxy rational origin will be established.

Astrophysics at Home. Further Hunting for Possible Micrometeorites.

Authors: Giuliano Bettini
Comments: 11 pages. In English

This paper follows "Astrophysics at home. Micrometeorites" posted in Vixra on 15 Feb 2011. As Jon Larsen says: "Up until now splendid research on MMs has been executed at secure localities (the South Pole well, prehistoric layers beneath the Indian Ocean, at the Greenland ice cap, etc), but consistent research in order to identify the similar objects found for instance in our populated areas, is practically absent". I present here a lot of new specimens found in a city environment, photos, a lot of questions and few answers.

The Structuring Force of Natural World

Authors: Jin He
Comments: 13 pages. In chinese

The assumption that the mass distribution of spiral galaxies is rational was suggested 11 years ago. The rationality means that on any spiral galaxy disk plane there exists a special net of orthogonal curves. The ratio of mass density at one side of a curve (from the net) to the one at the other side is constant along the curve. Such curve is called a proportion curve. Such net of curves is called an orthogonal net of proportion curves. I also suggested that the arms and rings are the disturbance to the rational structure. To achieve the minimal disturbance, the disturbing waves trace the orthogonal or non-orthogonal proportion curves. I proved 6 years ago that exponential disks and dual-handle structures are rational. Recently, I have also proved that rational structure satisfies a cubic algebraic equation. Based on these results, this paper ultimately demonstrates visually what the orthogonal net of proportion curves looks like if the superposition of a disk and dual-handle structures is still rational. That is, based on the natural solution of the equation, the rate of variance along the 'radial' direction of the logarithmic mass density is obtained. Its image is called the 'basket graph'. The myth of galaxy structure will possibly be resolved based the further study of 'basket graphs'.

"Aspin Bubbles" and the Force of Gravity

Authors: Yoël Lana-Renault
Comments: 9 pages

Based on the "Aspin Bubbles" theory, we will demonstrate that the force of gravity between two neutral matters is always a residue of the electrical forces that act among their elementary particles.

"Aspin Bubbles" and Gravitational Deflection

Authors: Yoël Lana-Renault
Comments: 10 pages with 4 figures

Based on the "Aspin Bubbles" theory, we propose a velocity function v(r) for light that is exclusively dependent on the gravity g(r) that exists at each point P(r) of space, and with which, by applying the laws of refraction, the gravitational deflections of light measured up to this point are obtained .

A Possible Alternative to Dark Matter

Authors: I. V. Grossu
Comments: 2 pages.

Inspired by existing theories that consider modifications of Newton's law for extragalactic systems, I propose, as an alternative to dark matter, the existence of a new force, constructed in an analog way with the magnetic field. In this context, an encouraging qualitative agreement with the rotation curves of disk galaxies was obtained. It is important to emphasis on the very basic level of the treatment presented in this paper. Further analyses along those lines are currently in progress.

Two Gravitational Singularities

Authors: Javier Bootello
Comments: 3 pages.

This article presents a virtual gravitational potential, which could explain some recent astronomical singularities: the secular increase of the eccentricity of the orbit of the Moon and the increase of the Astronomical Unit. Anyway, it is a theoretical potential without any proof of its physical reality.
