Reciprocal System Research Society

The Reciprocal System Research Society (RS2), formerly the International Society of Unified Science, is a 501(c)(3) non-profit, educational, scientific institution dedicated to promoting and extending the Reciprocal System of theory originally published by Dewey B. Larson in his 1959 book, The Structure of the Physical Universe. The society is based in Salt Lake City, Utah, USA.

The Reciprocal System of theory

The more complete understanding of physical existence opens the door to an exploration of existence as a whole, including those non-physical areas that have hitherto had to be left to religion and related branches of thought. It is now evident that our familiar material world is not the whole of existence, as modern science would have us believe. It is only a part—perhaps a very small part—of a greater whole.

—Dewey B. Larson, Universe of Motion, 1984

The Reciprocal System of theory (RS theory) was created by engineer Dewey B. Larson in the 1950s, where he proposed a model of the universe based on the concept of motion as primary to matter. It did not get much, if any, recognition simply because researchers could not adjust to the concept of motion without something actually moving.

Larson did discover something quite remarkable: the precise, dimensional relationship between space and time. By using that relationship, he was able to build a theoretical universe based on two postulates that closely resembles the observed universe, at both small (subatomic) and large (galactic) scales. Larson predicted some events that must exist as a logical consequence of his postulates, which had not yet been discovered, from new forms of atomic disintegration to quasi-stellar objects.

The Reciprocal System was, however, just a really good first draft of a generalized theory of everything (TOE), and does have its problems. Two of the members of the International Society of Unified science, Prof. KVK Nehru of India and Dr. Bruce Peret of the United States, discovered that research done in the areas of alternative science and philosophy had found solutions to these problem areas and took it upon themselves to do a reevaluation of Larson's original concepts, merge them with these other understandings, and see what resulted. The result is RS2—an updated version of Larson's Reciprocal System that provides integrated solutions to the problems discovered with Larson's original system.

RS2 is, by no means, purported to be the ultimate answer to life, the universe and everything. It is nothing more than a second draft of Larson's Reciprocal System (hence the name, RS2). We are constantly updating and revising it as other problem areas are found, or better solutions become evident.

We don't expect it to ever be accepted as a mainstream "theory of everything" and don't even promote it as anything but theoretical research, particularly since it scares conventional scientists with its references to mathematical concepts such as projective geometry, and philosophical concepts such as Theosophy and Anthroposophy. But what we are after is the truth behind the design of the Universe. We are making our research available here for the benefit of those who are interested in seeking this kind of truth.

This site presents a summary of some of our ongoing research and includes material introduced in the RS2 Theory discussion forums. Please visit the forum for recent developments.
