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.

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 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'.

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.

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 .

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.

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.
