SCP-XXXX in its spherical form
Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept in a standard storage vault that is vacuum sealed1, in a location not prone to seismic disruptions such as earthquakes. SCP-XXXX should be contained in a chamber that is guaranteed not to move, since any momentum SCP-XXXX is allowed to gain is a risk to its safe containment. Transporting SCP-XXXX is a difficult task, it must be transported in the most stable possible way as to avoid making the object move within its container.
Description: SCP-XXXX can appear as different rounded shapes, notably a sphere or an
ovoid2
SCP-XXXX came to our attention after it was reported to us during incident #4886 (see addendum).
SCP-XXXX is a classified anomaly since it is a 4 dimensional sphere being projected into our three dimensions.
SCP-XXXX exists in a fourth spatial dimension, meaning that whenever it starts moving, it becomes highly unstable and is prone to changes in its physical structure, such as growing to an observed maximum diameter of 10m, and shrinking to a smallest observed diameter of 1.5pm, beyond which it vanishes from the 3d dimension, and for it to return it is a matter of pure luck as to when and where it will return to our 3 dimensional plane.
Other changes that SCP-XXXX can be subject to when moving include the sphere being warped into an oval shape, and being warped to the point where the oval appears to bend over on itself.
The largest danger with SCP-XXXX lies with its ability to change shape in a fast and unpredictable manner. If it were to disappear and reappear within a solid object or a sentient being, it could warp whatever it is inside of beyond recognition by expanding inside of it.
