Welcome to the Reciprocal System

This site is dedicated to Dewey B. Larson's Reciprocal System of physical theory, a Theory of Everything that is based on the concept of motion, rather than matter. With only two, fundamental postulates, Larson was able to construct a theoretical universe based on just the inverse relation between space and time, that he called "motion." (It has nothing to do with something moving--"motion" is just a ratio between space and time that causes change.)

Larson's universe, referred to as the Universe of Motion, has some different premises than conventional theory:

  • Because mathematical relations are based on the multiplicative inverse (not the additive inverse), the condition of rest is unity--not zero. Larson calls this motion the natural datum, and is the speed of light. In Larson's universe, change is measured as a displacement from unity (the speed of light). A simple analogy to understand this concept is the see-saw, where the fulcrum is unity and distances are measured outward from the center, towards the far edges. Conventional science starts at the edges, measuring towards the center.
  • Because of this inverse, see-saw relationship of space and time, Larson's universe also contains two "halves" that he calls sectors. The first is the material sector, the one of our everyday experience, consisting of 3-dimensional space and clock time. Because of the reciprocal relation flipping across unity, he discovered the cosmic sector, the realm of 3-dimensional time and clock space. These two halves of the universe sit in opposition to each other, and are connected through his concept of motion.

As a result of this structure, the Universe of Motion tends to look inside-out to those with a conventional, scientific background--whom are usually the first to ask, "How can you have motion, without something moving?" Larson describes this as the "actors on the stage" approach, where you have things in a setting, and the two are entirely different from each other. Conventional science has "atoms" playing parts on the space/time stage of the Universe. In the Reciprocal System, however, the actors and stage are the same stuff--motion--acting in relative relation to each other. As such, the only fixed reference in a universe of motion is a speed--the speed of light, which Larson refers to as the "progression of the natural reference system."

If you wish to explore Larson's universe of motion, the following links are available, as tabbed sections:

  • RS theory: The main page of the Reciprocal System of theory web site, where announcements and site information is presented.
  • Library: Books, articles, audio recordings and videos about the Reciprocal System of theory. Material is added here as time and OCR skill permits.
  • Forum: A discussion forum concerning RS concepts. (We used to have an active phpBB forum, but having been hacked a number of times, eventually got damaged beyond useability.)
  • DB Larson: Biographical information on Dewey Larson, including photos and interviews.
  • ISUS: The International Society of Unified Science, a non-profit, scientific, educational corporation based in Utah in the United States that continues to keep the RS alive.
  • Store: On-line store where books on the Reciprocal System can be purchased. Some of these books are also available on Amazon, at a higher cost due to Amazon's fees.
  • RS2: Continuing research and development of the Reciprocal System, based on a correlation between Larson's theory and artificial realities used in computer simulations. RS2 has a wider scope than Larson's original work, and includes many extensions into the biological, psychological and metaphysical fields that Larson just started to address in his last book, Beyond Space and Time.
