These pages describe the "hard science" behind my "science fiction." In my earlier books I spent considerable time and effort gradually leading the reader from the real world into my own creations. When I wrote about the "reality field" I threw everyone into the mysterious globular cluster without warning, and sprinkled the science in later as needed. The boundary between my fiction and your reality is not simply some new technological breakthrough, it is an exploration of the regions science has yet to study. Exactly who is this "observer" science postulates in its formulae? Where do they live? These pages paint a picture of the path to the observer's door.
