This article is about the gravitational anomaly in the local universe. For the generalized mass concentration concept, see galaxy filament.
Panoramic view of the entire near-infrared sky location of the Great Attractor is shown following the long blue arrow at bottom-right.
The Great Attractor is a gravity anomaly in intergalactic space within the range of the Centaurus Supercluster that reveals the existence of a localized concentration of mass equivalent to tens of thousands of galaxies, each of which is the size of the Milky Way; this mass is observable by its effect on the motion of galaxies and their associated clusters over a region hundreds of millions of light years across.
These galaxies are all redshifted, in accordance with the Hubble Flow, indicating that they are receding relative to us and to each other, but the variations in their redshift are sufficient to reveal the existence of the anomaly. The variations in their redshifts are known as peculiar velocities, and cover a range from about +700 km/s to −700 km/s, depending on the angular deviation from the direction to the Great Attractor.
Thanks for posting that info on the Great Attractor. That was new news to me and so it was very interesting. I have never been a big fan of inflation theory so anything that brings that particular idea into question is always of interest.
Actually it was both :)
If anyone here is interested in a good read explaining the physics and offering an explaination for the Great Attractor, Stephen Baxtor has a series of novels about this phenomenon: “Ring”, “Flux”, and “Vacuum Diagrams”. or “ Xeelee: An Omnibus: Raft, Timelike Infinity, Flux, Ring by Stephen Baxter (2010)” “Vacuum Diagrams” offers more detail.
