A proposed 8-D theory of everything
This post is the exact same post as Anamorphose Elephant-Girafes, but it warrents it's own page focusing on the physics side.
While Anamorphose Elephant-Girafes brilliantly demonstrates the significance of perspective, this video shows how that is not simply a metaphor, but possibly the fabric of reality.
Where the sculpture is creating a 2D representation of a 3D object, the 8D symmetry is creating a 3D representation of an 8D object. It's 3D simply because we are ignoring the other 5 dimensions when looking at it, just as if we were looking at a 3d shadow.
