SCP-XXXX's gravitational effect1.

Item #: SCP-XXXX - "The Greatest Attractor"

Object Class: Keter

Special Containment Procedures: Due to SCP-XXXX's distance, mass and size, any physical means of containing SCP-XXXX using technology currently at the Foundation’s disposal is impossible. Implanted Foundation agents in major observatories and space programs are to contain images of SCP-XXXX, research data of its gravimetric effect2, as well as scientific theories which would cast doubt on the ongoing cover story. An ongoing misinformation campaign is in effect, currently aimed at perpetuating the existence of the Norma Cluster to ease compliance with current physics models. This campaign has thus far been able to completely suppress any knowledge pertaining to SCP-XXXX from public awareness.

The Foundation’s DEep spaCE anoMalous oBservER (DECEMBER) satellite is to monitor SCP-XXXX from an Earth-trailing orbit and report all sudden activity regarding SCP-XXXX to Foundation Observation Sites

Description: SCP-XXXX is an intergalactic gravitational anomaly located at the center of the Laniakea Supercluster3. The anomaly’s position on Earth’s celestial sphere resides within the area of the sky which is obscured by the Zone of Avoidance. This makes SCP-XXXX currently impossible to directly observe due to the obscuring effects of the Milky Way’s galactic plane. As such, the properties of this anomaly were determined by noting its measurable effect on galactic clusters across a region of several hundred million light-years.

Measurements taken of SCP-XXXX suggest that it is a highly localized concentration of mass many thousands of times more massive than the Milky Way galaxy. Current physics models place such a mass-heavy physical structure as an impossibility. In addition, current gravitational models using data recorded by the Foundation’s ‘DECEMBER’ satellite suggest that SCP-XXXX is attracting the Milky Way’s galactic cluster towards it at a rate of 7.1 Mm/s.

Galactic clusters determined to be opposite SCP-XXXX from the Milky Way’s are all blueshifted, in accordance with Hubble’s Law, indicating not only that they are approaching SCP-XXXX relative to the Milky Way’s and to each other, but the variations in their blueshift are sufficient to reveal the existence of the anomaly. The variations in their blueshifts cover a range of velocities from about +700 km/s to +100 km/s, depending on the angular deviation from the direction to SCP-XXXX. Variation in velocity was also dependent on distance from SCP-XXXX, with a range covering ███ █m/s to 5.1 Mm/s. Should the Milky Way follow this velocity trend, galactic ██████████████ as a result of SCP-XXXX’s gravitational influence is expected to occur in ███ million years.

SCP-XXXX was first discovered by civilian astronomers in 198█ following a series of observations by X-Ray astronomer Dr. ████ █████ in █████,█████████, the target of which appeared to violate the idea of uniform universal expansion. SCP-XXXX has only continued to display properties which place it in stark opposition to conventional astrophysical theory.

Following Event-XXXX-20██-09, it is imperative that the Norma Cluster cover story is upheld with the utmost priority. Efforts of Sites tasked with observing SCP-XXXX is to be focused on recording any similar incidents, discern how SCP-XXXX was able to ██████████████ an entire galaxy in just █ hours and develop methods to stop the proccess.
