Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

Later in the novel, two interstellar ships enter a four-dimensional fragment of space. While within this fragment, the crew of the ships can enter the fourth dimension. From the fourth dimension, they can see the interior and all sides of any 3D object, much like how humans can see every aspect of a 2D shape from the third dimension.
Greene offers up a garden hose as a good example of what the fourth dimension looks like. From far away, this garden hose may look one-dimensional to the naked eye. From a distance, we simply can ...
A temporal dimension, or time dimension, is a dimension of time. Time is often referred to as the " fourth dimension " for this reason, but that is not to imply that it is a spatial dimension [ citation needed ] .
An illustration from Jouffret's Traité élémentaire de géométrie à quatre dimensions.The book, which influenced Picasso, was given to him by Princet. New possibilities opened up by the concept of four-dimensional space (and difficulties involved in trying to visualize it) helped inspire many modern artists in the first half of the twentieth century.
In four-dimensional spacetime, the analog to distance is the interval. Although time comes in as a fourth dimension, it is treated differently than the spatial dimensions. Minkowski space hence differs in important respects from four-dimensional Euclidean space.
Extra rare is another temperature category and means a steak is only cooked to 115 degrees - which isn't as worrisome as eating raw beef, but is still far from being considered safe to eat.
