Key To The Extraterrestrial Messages

This document, published in the NSA Technical Journal (Vol. XIV, No. 1), presents an analytical attempt by H. Campaigne to decode a series of 29 messages described as originating from outer space. The author builds a systematic key to interpret the messages, which are composed of symbols representing digits (A through G and N) and operators (L, K, M, O, S, T, V, Q, JNV, NKV, NLV). Through iterative parsing and hypothesis testing, Campaigne identifies patterns that suggest the messages contain mathematical and logical structures. The author posits that the messages utilize binary operators for arithmetic, Boolean logic, and set theory. Notably, the author identifies a sequence of symbols that appears to correspond to the periodic table of chemical elements, with specific groupings of symbols representing elements or groups of elements. The author concludes that while the syntax and values of the extraterrestrial culture remain complex, the use of fundamental concepts like numbers, sets, and physical constants suggests a commonality between the sender and human civilization. The document includes an appendix listing the 29 messages in their original symbolic form.
