    Abstract: The space-time structure of gravity mass is analyzed in this paper. It is proposed that "spin angular momentum and rotational angular momentum" are intrinsic properties of gravitational mass, and "curvature and gravitational effect" are representations of gravitational mass. The theoretical basis of the universal gravitation constant (G=1/16𝝿C) is... Show More

    Abstract: Study Aim: The problem as to whether planets, moons and planetary ring-systems are randomly or non-randomly distributed in the solar system has not been resolved. In this article, the predictions of Chime’s laws for distribution of bodies were critically examined in order to see if planets, moons and planetary ring-systems were randomly or non-rand...

    Abstract: The beginning of the formation of galaxies can be recognized in the planetary and stellar systems. The rotation speed of a galactic center determins the form of a galaxy an the ongoing processes. The forces of attraction and the rotation of stars firstly form binary systems. The objects that are locked down by their tidal forces or that posses an e... Show More
  • Lithopanspermia – The Terrestrial Input During the Past 550 Million Years

    Abstract: An estimate for the minimum amount of terrestrial material deposited into interplanetary space over the past ~550 million years is made. Using the published characteristics of known terrestrial impact craters, it is found that at least 1013 kg of potentially life-bearing matter has been ejected from the Earth’s surface into the inner solar system. ...

    Abstract: The discovery of pulsar is an exciting discovery in 1960s, it has a profound influence on the development of modern physics. Although after the discovery of the first pulsar, it is quickly confirmed that pulsars are rapidly rotating neutron stars, yet people knew little about the essential mechanism leading neutron stars to pulse electromagnetic ra...
