This (hard) question we still try to answer with the discussion in the previous papers The Moon Creation And Motion (IV) The Moon Creation And Motion ( V) The Moon Creation And Motion (VI) The paper provides a clear question let's consider it for a while -The moon data shows that, the moon diameter is created based on geometrical calculations- We have seen many proves for this fact in that papers -So –Why AND How? Should be the questions -Why the moon diameter is created based on geometrical calculations? Because The Earth moon mass is created relative to Jupiter Mass! This proportionality between Jupiter Mass and the Earth Moon Mass causes the geometrical calculations! Such answer can be acceptable?! -(First) Why does Jupiter Mass define the Earth Moon Mass?! and (Second) Why the proportionality between Jupiter and Earth Moon Masses causes the geometrical calculations?! -Jupiter defines the Earth Moon mass because Jupiter is the inner planets Parent – means – Jupiter defines all inner planets masses and the Earth moon isn't different from the other inner planets! This is my answer! How to prove? -Why does the proportionality between Jupiter mass and the Earth Moon mass produce geometrical calculations? -Spite the idea is hard – it's clear in this abstract perfectly – So we need to move logically with it inside the paper step by step – (1st step) I provide data proves that the moon diameter is created based on geometrical calculation (2nd step) we will review the answer of the question why does Jupiter define the Earth Moon mass (this question we have answered in that papers) – (3rd step) we will try to understand why the proportionality between Jupiter and the moon masses can produce any geometrical calculations or rules (and this is the new part of discussion) Gerges Francis Tawdrous +201022532292
