A Structure of Dark Matter 【Reused】

May 20, 2016  Publication

○I wish to suggest a structure for dark matter. This structure has novel features which are of considerable cosmological interest.
○A structure for particles of dark matter(:dark particles) has not been proposed yet. Only the models of large scale structure of the universe are proposed. In my opinion, these models are unsatisfactory for two reasons:
(1)I believe that the retention force which gives the dark matter halo is the structure of dark particles, not the nature of gravity. Without the structure of dark particles it is not clear what dark matter halo would hold such large structure.
(2)The models of large scale structure appear to be too large.

○Atomic structure is almost empty, however has a large volume. In Bohr model [1] the size of atom is a diffuse cloud of negatively charged electrons surrounding a small, dense, positively charged nucleus.

○I wish to put forward a new structure for dark matter. This structure is something stereoscopic based on sphere. Several models are considered. (see Figure1)
○I have made the usual quantum physical assumptions, namely, that each dark particles in close proximity are held in a single orbit by the centripetal force of gravity.
The two orbits are related by electromagnetic radiation. But such radiation is not observed.
○Each dark matter clusters pass with little affected in the collision of galaxy clusters. I have assumed the radius of the orbit is much larger than particle.
Figure1 Examples of the structure [2] [3]

○The dark matter halo surrounding the spiral galaxy appears to have 10 times huge spherical structure of the galaxy. If dark matter forms such 3-dimensional structure, then the huge structure is automatically determined. (see Figure2)

○The dark matter halo always has been suggested the existence of the particle structure.

○It has not escaped my notice that the structure of dark matter I have postulated immediately suggests a possible quest for identity of the dark matter.

I am much indebted to Internet, especially Google and Wikipedia for constant information.
I have also been stimulated by knowledge of the online course of cosmology of Dr. Brian Schmidt and Dr. Paul Francis at Australian National University [5], Hitoshi Murayama at The University of Tokyo [4].
