Gravity Model of Black Holes and Solar Planets

By considering that gravity changes at increased elevation contribute to change in velocity we can obtain timescale variation related gravity as alternative to time dilation related space-time curvature. Gravity changes around planets and black holes are revisited by introducing a gravitosphere model where gravity works inside and around planets. Resulting gravitospheres related to planets and black holes radius shows evidence for a critical Radius of a star to develop black hole structure. Internal structure based gravity and velocity variations of black holes is suggested by including captured asteroids input which results in phase transformations and release of kinetic energy. These processes may explain vibrations related radiations, an adapted volcanic style with possible escape of particles and gravitational waves from horizon zone. By assuming that gravity control velocity changes and related structures it will provide the first elements of a universal gravity model.
