In this present work SITA simulations were used to find out Theoretical star circular velocity curves in a Galaxy (star circular velocity verses star distance from the center of galaxy), depends on various initial conditions and are never half bell shaped curves as predicted by Bigbang cosmologies. Here we are presenting four main cases. In the first case A Galaxy with a huge central mass with star like masses in presence of external galaxies were taken. Theoretical prediction of circular velocities were matching with the observed velocities. In the later cases either Huge central mass was absent or external galaxies were absent or both were absent, the theoretical circular velocities did not match the observations. Hence the question of missing mass does not arise.
Large-scale structures of universe could not be explained by Big bang based theories using additional repulsive forces like ``Einstein's λ'', as it requires isotropy and homogeneity. Our universe is neither isotropic nor homogeneous. It is LUMPY. And there is no gravitational repulsive force found in the universe even after almost a century after publication of General theory of Relativity. We find that for all fringe effects, Special theory of Relativity is sufficient. Things can be explained by Newtonian gravitation. This proves Galaxy disk formation require some external forces other than self-gravitation of Galaxy it self. Here the there is universal gravitational effect at that position and time are calculated due to ALL the bodies present in the universe. This forms a repulsive force. And this force varies with time, position, structure, masses, their distances, their dynamic movement etc.
SITA (Simulation of Inter-intra-Galaxy Tautness and Attraction forces) was successful in the formation of Dynamic universe model where Blue shifted Galaxies were also present (Paper presented by SNP. Gupta, GR17, Dublin, 2004 & Presented in ICR 2005 International Conference on Relativity) , at Amravati University , India, Jan 11- 14, 2005. Testing of model and its behavior at micro sec, 1 sec, 1 month, I year , 10 year done. The pictures show a non- collapsing mass distributions and formations of orbits due to mutual gravitational attraction forces. (paper presented by SNP. Gupta, Brit Grav 4 , Oxford, 2004).
