Now we can return from physical cosmologies to pure geometry. The combined "tree of life" (antipode hypercube) and "tree of death" (antipode hypertetrahedron) is the tesseract at antipode. A tesseract is another form of depiction of the hypercube, just as is the torus of the hypersphere. When the tesseract is seen from above one of its faces, it forms the shape of the cube within-within-a-cube, or hypercube, of a cube over time. When the tesseract is seen from above one of its edges, it appears at "antipode" as the combined trees of life and death, whose fruits are longevity and fore-knowledge. When the tesseract is seen from above one of its corners, it appears as a 3-dimensional form of a Moebius strip or Gordian knot, where, by the Pythagorean theorem, a flat, 2-d pattern can be twisted into a 3-dimensional shape. The shadow itself becomes an object.
