According to Quantum FFF Theory, Empty space is filled with a fast oscillating lattice of massless Axion-Higgs field particles as a part of our opposing dipole pressure Axion-Higgs-graviton gravity on earth. Now prof. Yehuda Hoffman shows us a support for an extra hypothesis of an extra gravity effect between dark energy overdensity push from material voids and dark matter pull from Black hole and material concentrations.

The dipole repeller is a center of effective repulsion in the large-scale flow of galaxies in the neighborhood of the Milky Way, first detected in 2017.[1][2][3]
The Local Group of galaxies is moving relative to the cosmic microwave background (CMB) at 631±20 km/s.
There is also a pattern of bulk flow in the motion of neighboring galaxies extending to distances of over 250 megaparsecs (Mpc). There is a known overdensity – the Shapley Supercluster – creating an attraction in the flow of galaxies. That single center of attraction along with a roughly equal single repeller appear to be the most significant contributors to the CMB dipole.
The repeller appears to be located at a distance of about 220 Mpc and is anticipated to coincide with a void in galaxy density.
Fundamentally gravitation is always attractive, but if there is an underdense region it effectively acts as a gravitational repeller. That's because there is less attraction in the direction of the underdensity, and the greater attraction due to the higher density in other directions acts to pull objects away from the underdensity[4]
