History Main / MoreThanThreeDimensions

* ''Series/TheGoodPlace'' implies that reality has nine dimensions. Humans just can't see them, hence why Michael apologises for the mess in his office despite it looking spotless.

* ''Fanfic/ChildOfTheStorm: The Spirit of the Fallen Fortress, being a minor EldritchAbomination, enjoys playing with physics [[DomainHolder in its domain]]. When it [[DemonicPossession possesses]] [[spoiler: Hermione]] and unleashes her full [[RealityWarper reality-warping]]] potential as [[spoiler: a wielder of Chaos Magic and an Omega Class space-manipulating mutant]] filtered through its own sadism, the result is the kind of fractal based physics warping that requires either multiple PhDs or some serious drugs to understand. Then it goes [[WorldGoneMad full]] [[AlienGeometries Escher]].

* ''VideoGame/{{4D Toys}}'' is an early demo using the same engine that was designed for Miegakure.

* ''VideoGame/HalfLife2'': In a very arcane (and [[FreezeFrameBonus Blink And You Miss It]]) GeniusBonus, Dr. Judith Mossman quips about the resistance's superior, if somewhat [[FlawedPrototype unstable and homebrew]], [[TeleportersAndTransporters teleporter technology]]:

* "No-Sided Professor" by Martin Gardner is about a mathematician who discovers a topological shape which doesn't have ''any'' sides (in the same way that a Möbius strip only has one). Folding something into this shape causes it to disappear into a higher-dimensional space.

* Played straight (in the "time is a fourth dimension" variant) and extensively explored in ''Discworld/{{Pyramids}}''. The shape of a pyramid allows it to be a dam in the flow of time, which causes the dimensions to get flipped around in strange ways in their vicinity; for example, one unlucky man becomes thinner than a sheet and begins to move continually to the right. All his dimensions have been shifted, so time became breadth. (They stop him aging by putting a large rock in front of him.)

* ''TabletopGame/GURPS Powers:The Weird'' has rules for 4 dimensional beings and [[CrazyAwesome 4D martial arts]].

* A tesseract is a classic example. It's a cube with four spatial dimensions. The name even means "four rays" because at the corners of the tesseract there would be four lines all at right angles to each other. [[SchmuckBait try and visualize that.]]

* ''WesternAnimation/TheSimpsons'' parodies this trope in "Treehouse of Horror VI", where Homer ends up in a seeming EldritchLocation... one that renders everything, including himself, in ConspicuousCG. When people try to rescue Homer and figure out what happened to him, Dr. Frink explains that Homer is trapped in "the third dimension", something baffling to the people of the two-dimensional Springfield.

Frequently found overlapping with AlienGeometries. The distinction between the two is that under normal circumstances (well, as normal as this sort of thing can be anyway) an object occupying more than four dimensions will still follow all standard rules of normal euclidian geometry [[note]]perpendicular angles are 90 degrees, parallel lines never intersect, squares have straight edges, the angles of a triangle add to 180 degrees, ect.[[/note]]. If the additional dimensions are ''curved'', however, normal geometry points to Creator/MCEscher and [[PassThePopcorn grabs a bucket of popcorn]].

* 4D and above variations of ''VideoGame/{{2048}}'' can also be found online.

** Mxy's realm has always been referred to as "the Fifth Dimension," but is usually depicted just as a typically weird comic bookity alternate universe (usually as a cartoon-style {{Wackyland}}. Occasionally, though, a writer will explore the [[AnotherDimension implications of the name.]] One time, Superman had to rescue one of Mxy's people from a [[AlwaysABiggerFish cosmic threat]] that was reducing him to only three dimensions. The entity attacks Superman, stripping away one of his dimensions and briefly turning him into a flat, two-dimensional image.

* The goddesses and other heavenly beings in [[AhMyGoddess]] are 10-dimensional entities (in the "string theory" sense), not that it comes up very often. This means that, ostensibly, [[FridgeLogic Keiichi can only perceive and interact with three dimensions of his ten-dimensional love interest.]]
