The SCP Foundation has contained and encountered many forms of Alien Geometries. Spatial anomalies are so prevalent, in fact, that the Foundation has task forces that specialise in dealing with them, such as the Mole Rats
and Angle Grinders. Some of the spatial anomalies in the SCP universe are:
- SCP-001 ("Dr. Mann's Proposal"). The SCP is a gravel path in a wooded area. When traveled counter-clockwise the path is continuously uphill regardless of how far the traveler goes.He found the path did not conform to the pure geometry of Euclid.
- SCP-004 ("The 12 Rusty Keys and the Door"). Ten of the keys open the door into a dimension where the laws of physics and topology are very different from normal. Anyone entering this dimension is ripped apart, with their body parts disappearing.
- SCP-084 ("Static Tower"). The Static Tower generates a form of radiation that has a detrimental effect on the space/time reality within SCP-084's active area. This can (among other things) cause the distance between objects to instantly increase or decrease.
- SCP-167 ("Infinite Labyrinth"). The set of rooms and doors reachable through SCP-167 don't follow the rules of Euclidean geometry. If going through two separate series of doors in real life would lead to the same place, they don't in SCP-167.
- SCP-184 ("The Architect"). SCP-184 increases the interior size of buildings. After it's been working for a while things inside the expanded areas start to get so strange that it drives people insane. There's also a tale out there that suggests it's actually the true SCP-001 due to the fact that it has no upper limit. You ever wonder why the universe is constantly expanding?
- SCP-413 ("Endless Garage"). SCP-413 regularly changes its interior dimensions to cause people inside of it to become lost. Because of this, any Foundation personnel who enter SCP-413 are required to use GPS or safety lines to find their way.
- SCP-419 ("Window to the World"). A cityscape can be seen through SCP-419. The buildings are similar to those of the Victorian Era on Earth but appear to be unusually twisted or warped and based on non-Euclidean geometry.
- SCP-455 ("Cargo Ship"). In addition to the ship being Bigger on the Inside, it regularly changes its internal structure in bizarre ways to trap and harm intruders and inflicts audible and visual hallucinations on them.
- SCP-487 ("The Impossible House"). Moving or removing any of the supernatural objects inside SCP-487 has variable effects, such as changing the internal structure of the house or causing anomalous events outside of it.
- SCP-648 ("The Labyrinth"). The maze-like interior of SCP-648 changes on an unpredictable basis, often cutting off personnel inside it from the exit. Over 14 square kilometers of SCP-648 has been explored without reaching any exit or edge.
- SCP-850 ("School of Fish"). SCP-850 is a school of fish resembling herring. It is an anomaly in which space is bent, resulting in (among other things) the area inside it being larger than its actual volume.
- SCP-915 ("The Mechanotesseractic Computer"). The interior of SCP-915 has a highly non-Euclidean internal configuration, with extensive outpocketing in space and time and a locally nonflat spacetime. The interior experiences constant shifts and is mentally unsettling to anyone inside it, often causing disorientation, nausea, and fainting.
- SCP-970 ("The Recursive Room"). SCP-970 is a collection of rooms that are connected by a series of doors in a straight line. If a person walks through the doors in order, they'll end up back at their starting place.
- SCP-1130 ("A Handy Shortcut"). The areas encountered while passing through SCP-1130-2 are connected in a random fashion: for example, a hatch in a World War II German submarine leads to a room in a hospital, and a subway tunnel connects to a kitchen in a diner.
- SCP-1323 ("A County Fair"). The complex system of underground rooms and passages under the fair are topologically inconsistent: they don't follow Euclidean geometry and don't intersect with each other the way they should.
- SCP-1351 ("Moebius Cave"). The cave has one floor and one wall. Over the course of its length the floor "wraps around" to become the ceiling and the wall "wraps around" to become the other wall. Also, the direction of gravitational pull changes to match the local floor.
- SCP-1555 ("Facility"). The inside of the underground part of SCP-1555 is Bigger on the Inside and a shell fired by SCP-1555 had Clown Car qualities.
- SCP-1936 ("Daleport"). The area of SCP-1936 is filled with spatially anomalous locations that are topologically inconsistent, due to the several Cosmic Entities summoned there for a free-for-all. These include doors that lead to different places at different times and corridors that lead to multiple locations. One of the creatures summoned was "a fractal-shaped sheet of motile skin" leaping across rooftops.
- SCP-2264 ("In the Court of Alagadda"). The architecture of SCP-2264 is non-Euclidean and law of gravity isn't consistent. The city's inhabitants can be seen climbing a stairway upside-down, but as they see it gravity is normal.
- SCP-2282 ("Goat."). SCP-2282 appeared to be a normal goat. Its digestive tract was a set of non-Euclidean spacial distortions that increased its internal volume to at least 17,000 cubic meters, made up of more than 8,000 separate stomachs.
- SCP-2764 ("The Eldritch Antarctic"). The area in a radius of 50 kilometers around the Eldritch Abomination SCP-2764 is subject to alterations in time and space that cause great difficulties for mortal beings (like humans). SCP-2764 appears to decrease in size as observers approach it, and it sometimes appears to teleport from place to place within the area, indicating that its position in inherently uncertain.
- SCP-2976 ("Hall of the Last King"). When people infected with the SCP-2976 meme advance to Stage 4 they start to create the Hall of the Last King. The structure has non-Euclidean dimensions and architecture, with time and space being warped inside it.
- SCP-4001 ("Alexandria Eternal") consists of a tunnel below Alexandria, Egypt that leads down to an antechamber that connects to a staircase which then descends 15 more meters below ground. The staircase emerges from a roofless 12-meter-high tower into a large room stacked with bookshelves. The room does not conform to Euclidean geometry; it's possible to walk in any one direction and eventually return to the point of origin. The Foundation has also tried to drill into the room from the side, but has only encountered more soil instead of the expected bookshelves.
