Newly Discovered Dipole Repeller is Pushing Our Local Group of Galaxies Through Space

For decades, astronomers have known that our Milky Way galaxy, together with our companion Andromeda galaxy, are moving through space at about 1.4 million miles per hour. Scientists have generally assumed that excessive gravity from two dense regions of the universe, known as the Great Attractor and the Shapley Concentration, were responsible for this motion. But now, in a groundbreaking study, a team of researchers is reporting the discovery of a previously unknown and nearly empty region of space located in the opposite direction that is effectively exerting a repelling force and pushing our Local Group of galaxies through space. This void has been dubbed the "Dipole Repeller."
