Because of gravitational repulsion stasis is achieve and it becomes impossible for material between the galaxies to been exchanged. [QUOTE]
Have you been able to define a mechanism that could account for the existence of a gravitational repulsive force or potential.
I believe the space-time geometry of the general theory relativity which is used to define the gravitational potential of particle does not and cannot support the existence of a negative gravitational potential you have assoicated with an antiparticle. Therefore, if the scientists at CERN do find that
anti matter particles fall up because they posse a negative gravitational potential we would be required to not only to rethink the relationship between matter and antimatter but completely revamp our understanding of the mechanism responsible for gravitational forces and the geometry of the universe.
