    Abstract: The pursuit for the essence of gravity brought a graphical model for radiant cold-heat versus distance and mathematical models for the planets’ axial tilt, orbital and axial period of rotation out of the Sun’s radiant heat and the distance therefrom which in turn brought the following results:- The Solar system is held and driven by cryo-thermodyna...

    Abstract: We propose another version of Black Hole information Paradox owing absence of Diffeomorphism symmetry for Black Hole Spacetime. The central idea is assumptions of semiclassical Gravity like locality, causality and diffeomorphism symmetry lead to another paradox. The paradox unlike many other recent versions of Information paradox is valid even at v... Show More

    Abstract: This paper evaluates the comparision of IRI-2020 and AfriTEC ionospheric models in predicting TEC variations during geomagnetically disturbed time over East Africa in case of Ethiopia. In equatorial places like Ethiopia, the geomagnetic disturbance of the ionosphere can cause significant changes during disturbed time, which could lead to inaccurate... Show More
