The motion of Solar system round the Galaxy center is considered in this article. Joint use of geochronological and astronomical data allowed to determine parameters of galactic orbits of Solar system in the Phanerozoe. As a result of the analysis the duration of some geological periods are modified and the new geological period is entered. The future duration of the Quaternary period is calculated also and is defined more exactly duration of the first period of the Phanerozoe - Vendian.

Geomagnetic field is important to every life, forming of which has not been explained well. This paper linked lodestone on earth and distance from earth to sun to explain forming of the geomagnetic field. Finally found that key to forming the geomagnetic field is distance from earth to sun. Affected by this distance, the matter earth gets from sun is special magnetic energy particles, which promotes to form lodestone, magnetic energy from which is stored in lodestone. Much lodestone on earth makes up a huge magnet, which release unified magnetic energy to make up the geomagnetic field.

Despite casting deep doubt on dozens of theoretical papers on "elastodynamic" cloaking, the new study's authors from the Georgia Institute of Technology don't think civil engineers should completely give up on it, just on the idea of an ideal cloak. 
University of Southern Denmark researchers have conducted simulations of dark matter particles hitting the Earth. 
A global team of scientists, including two University of Mississippi physicists, has found that the same instruments used in the historic discovery of gravitational waves caused by colliding black holes could help unlock the secrets of dark matter, a mysterious and as-yet-unobserved component of the universe. 
The lack of so-called “dark photons” in electron-positron collision data rules out scenarios in which these hypothetical particles explain the muon’s magnetic moment. 
In this paper, we present the details of the proposal for definition and implementation of a unified geodetic referential for the countries of North Africa as : - the choice of the system of the referential, - the steps of the realization of the project, - the training of the geodesists working on the project.
