Constant Acceleration in Fractal Structures with Fractal Dimension D = 2

An unexplained acceleration on the order of 10–8 cm s–2, which is close to cH, where c speed light and H Hubble constant, detected in gravitationally bound systems different scales, from solar system clusters galaxies. We found that any test body located inside a fractal structure with dimension D = 2 experiences same confirmed previous work photons propagating through this decrease frequency owing gravitational redshift. The can be directed against movement body. distribution matter should at scales least hundreds megaparsecs few gigaparsecs for existence acceleration.
