we have discovered that any body in motion creates a virtual
by drawing its numerous positions extended ​through time.
Even though we have added time into the drawing, the image
produced still represents a three dimensional figure, although
greatly transformed.


By taking this process in reverse, it becomes possible to
produce a moving object from any volume, simply by
substituting time for one of its three special dimensions.
