Special Containment Procedures: Although presently impossible to contain, predictive models suggest no active containment measures are needed. SCP-XXXX poses no threat to Earth nor will it be visible with current publicly available telescope technology for at least 1,800 years. An O5 meeting is scheduled for 1/21/2059 (4 years, 303 days from today) to determine whether an update to SCP-XXXX containment procedures is necessary as optical technology advances.

The ATAs¹ will continue to autonomously search for appearances of SCP-XXXX. If an instance is detected that does not align with predictions, notify Dr. ABCD to rework models and elevate the global surveillance level to 4.

Description: SCP-XXXX designates a series of spatial phenomena. The consistent patterns across occurrences suggest that these phenomena are all closely related. Each observed instance will be detailed separately and ordered by date of detection.

First Detection
Date Discovered: 5/18/1971
Description: An approximately 8 meter in diameter sphere of unknown composition was spotted near Jupiter, five days after the completion of the first ATA. It was initially thought to be an error. While the seemingly “perfect” roundness of the object made it notable, the low resolution of the first ATA gave little data to work with and the event was only given a short description in the Extranormal Events document.

Second Detection
Date Discovered: 4/6/1999
Description: An approximately 5 meter in diameter sphere of unknown composition was spotted 0.5 LY from Earth by the third ATA. A high fidelity measurement taken 1.5 minutes later corrected the diameter to be 3 meters. After this, the object became increasingly difficult to track until it no longer appeared on region scans.

Third Detection
Date Discovered: 10/10/2017
Description: An initially 1.1 meter in diameter sphere of unknown composition was spotted 6.55 LY from Earth by the fourth ATA. As it was observed, it grew to a maximum diameter of 12.6 meters before shrinking back down. It was no longer detectable after shrinking below a size of 0.1 meters.

Fourth Detection
Date Discovered: 2/11/2020
Description: An initially 0.5 meter in diameter sphere of unknown composition was spotted 4.21 LY from Earth by the fourth ATA. As it was observed, it grew to a maximum diameter of 12.6 meters before shrinking back down. It was no longer detectable after shrinking below a size of 0.1 meters. The dates and locations of the four detections were given to an AI, which produced a model aiming to predict the next detectable appearance of SCP-XXXX. The model suggests that the appearances follow regular intervals, both spatially and temporally.

Fifth Detection
Date Discovered: 6/5/2025
Description: The fifth ATA was set to focus on a region of space predicted by an AI generated model, 9.551 LY from Earth. An instance of SCP-XXXX was detected, and grew and shrank in accordance with previously gathered data.

Sixth through Eleventh Detections
Date(s) Discovered: 11/1/2027, 9/6/2029, 4/10/2032, 5/5/2036, 6/4/2038, 2/22/2041
Description: The fifth and sixth ATAs found instances of SCP-XXXX at each predicted location. All followed established patterns. One detection done by the sixth ATA seemed to suggest a small object launched off of a shrinking SCP-XXXX instance. After the ninth detection, a high speed probe was launched in the direction of a future SCP-XXXX instance predicted to be 0.41 LY from Earth. It will arrive and make observations on 7/5/2049.

Twelfth Detection
Date Discovered: 7/5/2049
Description: A high speed probe arrived at a location 0.41 LY from Earth where a SCP-XXXX instance was predicted to appear. Before the appearance, four reflective spheroids converged on the predicted location, each eventually arriving and merging into a suddenly appearing SCP-XXXX instance as it grew. The instance did not have an atomic structure, but rather acted as a force field that reflected all tested wavelengths of electromagnetic radiation, and prevented matter from passing through. This gave the object the appearance of a spherical mirror. It produced a gravitational field that changed with the size of the sphere, which suggests a density of 9,007 kg/m3. Forces applied to the sphere did not result in any measurable change in acceleration, suggesting incredibly high inertia, despite the object's relatively weak effect on the gravitational field. As the sphere shrunk down, four spheroids flew out following a path normal to the sphere's surface, each in different directions and velocities. Eventually the sphere shrunk to a point of undetectability, likely disappearing altogether.

Zeroth Detection
Date Discovered: 10/30/1961
Description: Upon the detonation of the Tsar Bomb in 1961, the Foundation’s ASG² found an irregular column of stone within Earth's mantle, which suggested the impact of a small (<15 meter diameter) but incredibly heavy extraterrestrial object. All available dating methods suggest it struck around 2 million BCE. A recent revistiation found that the ends of the column have a shape consistent with the shrinking and growing of SCP-XXXX instances.

In order to cause such a feature, a SCP-XXXX instance would have to maintain its velocity and structure while pushing through hundreds of kilometers of rock.

The Nature of SCP-XXXX
A theory describing the mechanisms behind SCP-XXXX must account for the following:

• The changing size of instances, and the pattern followed
• The constant intervals in both space and time that instances follow
• The high inertia of instances, in contrast with the low gravitational effect
• The four spheroids that converge and diverge from appearing and disappearing instances

A study done by Dr. ABCD, available in the Foundation library with proper clearance, suggests that SCP-XXXX is a four-dimensional honeycomb made of tetracube cells. Each vertex is a hypersphere and each edge is a spherinder. Hyperspheres passing through our three-dimensional space produce the effect of a sphere changing in size. Spherinders passing through our three-dimensional space produce spheroids whose eccentricity and velocity depend upon each spherinder’s angle.

The high inertia of SCP-XXXX instances is a result of the total mass of the entirety of SCP-XXXX. While the connections are not apparent in three-dimensional space, they are always present in four-dimensional space and are almost perfectly rigid.

SCP-XXXX is likely artificial, although its purpose is unknown. Determining the function of the object could lead to unprecedented scientific advancement.

A radio transmission bounced off of a SCP-XXXX instance and into the sixth ATA with exact precision. While it appears to follow linguistic patterns, it has not yet been translated to readable text. The LSAN-6 Pattern and Language AI is currently processing the message for translation. See the remote console below.

Footnotes

1. Anomalous Telescope Array. Similar to conventional telescope arrays, the Foundation's ATA(s) make use of anomalous items and effects to achieve resolution far greater than that of conventional telescopes. The seventh ATA is currently being planned. The fourth, fifth, and sixth are still in use today while the first, second, and third have been disassembled.

2. Anomalous Seismograph Grid. The Foundation's ASG used anomalous items and properties in 80 seismographs located around the world. Combining high precision mesaurements from the seismographs, detailed models of Earth's crust and mantle were created when earthquakes occured. The ASG has since been replaced with systems not limited by timing of Earth's geological activity.
