Time is the 4th dimension in the theory of relativity and physics.
This is the 5th dimension
In mathematics the dimension of a space is roughly defined as the mimimum number of coordinates needed to specify every point within it.
so a line is one dimensional.
a square is two dimensional.
a cube is three dimensional.
a tesseract is four dimensional.
a penteract is five dimensional.
a hexeract is six dimensional.
a hepteract is seven dimensional.
an octeract is eight dimensional.
an enneract is nine dimensional.
a 10-cube is ten dimensional.
The two are not mutually exclusive.

in the first few seconds you will see a four dimensional object in a three dimensional world. From threshold.
Also a shadow is not a two dimensional object it is a three dimensional object. For a shadow to exist on a surface it must also exist on every plane between the casting object and the blocking surface, even if our perception does not register this . Thus a shadow is a grouping of rays of darkness, (contrasted by rays of light).
