All the assumptions and axioms
made so far can be considered as first
assumptions or first approaches,
such as statements about life or evolution, or the same
probabilities in nonsunlike star systems, etc. For more
precise future data, these assumptions can be further
differentiated, depending on requirements and
possibilities. As with any falsifiable model, newer data can be used to modify or even revise individual statements, although the overall structure and also the content of the present model remain valid. . MWith all equations, definitions, probability factors, axioms and propositions available to date, an approach is now available which is based on experimental and empirical data, allows differentiations at any time through future data and can therefore serve as a working hypothesis for probability considerations of extraterrestrial civilizations. . If, through future investigations, an ever better significance of the previous probability values is achieved (according to sentence 6.1.2 within the next two centuries), the probabilities of probability factors change into simple distribution or frequency values. This also transforms the probability model into a simple, empirical distribution model of planets, life, intelligence and civilizations in our galaxy.
