This may be because they are built on different foundation, Relativity on the foundations of space-time and quantum mechanics on the spatial foundations of momentum and position. On the other hand, Shadows demonstrates that these two theories have a common foundation by redefining the space-time geometry of relativity in terms of the geometry of four spatial dimensions. By redefining the relativistic concepts of space-time in terms of a spatial framework that is more compatible with the spatial framework associated with Quantum theory Shadows may provide one of the keys required to unite these two great theories. Shadows demonstrates the power that changing one perspective on the physical structure of the universe can have in helping humankind understand the mechanisms responsible for the physical laws and forces of nature. I am enough of an artist to draw freely on my imagination.
Imagination is more important than knowledge.
Knowledge is limited. Imagination circles the world.
