As per the scientists, Milky Way is being pushed through space by cosmic dead zone. It is known that our galaxy is being pulled through space, but cosmologists suspected it was being pushed as well.The constellation is loacated on the farthest side of Lacerta, the Lizard, the vast patch of nothingness appears to have a striking dearth of galaxies compared to the rest of its cosmic neighbourhood.
The Shapely attracter being the attracting obstacle, pulling the Wilky Way galaxy, but research showed the pushing force by a Dipole repeller. A 3D map of the nesrest galaxies show a steady flow of galaxies towards the Shapley attractor and away from another region of space almost directly behind the Milky Way on the same axis. The movement of Milky Way depend on the gravitational attraction attraction of the galaxies around. With increased distance from Wilky Way, the attracting force diminishes and at regions devoid of galaxies, give rise to repelling force
So from the studies done at Imperial College London even shows that with increased voids in space, lack of galaxies at a particular direction, leads to a pushing force ,with an attracting force from the distant and closely spaced galaxies around Milky Way.
