Paper Question -How The Earth Moon Is Created? -The Giant –Impact Hypothesis provides a good description about How the Earth Moon was Created… -I have suggested Mars Migration Theory which can solve many difficulties faces The Giant- Impact Theory and provides a very good answer for the question how the Moon was created? -Mars Migration Theory is reviewed in this paper introduction Now -Mars Migration Theory tells that – the Earth Moon was created by Mars Collisions With Venus & Earth and from these Collisions debris the Earth Moon was created in addition to Mars moons and the Asteroid belt But -If the Earth Moon is created from the collisions debris – why the moon diameter is created based on geometrical rules?! How to do that? Let's consider this question in more details… for example -The earth Moon diameter x the sun diameter = Jupiter orbital circumference – Why? this data is one of similar hundreds – for example – the moon diameter x the moon orbital motion distance (from perigee to apogee 43000 km) = Earth orbital distance…! I want to say… that -The Earth Moon Diameter was not created by any random process - Some Geometrical Power is found behind and forced the moon to have this (Specific Diameter & Circumference) which will be in harmony with all planets data as we have seen…! -What's this Geometrical Power? Is it the gravity force? can the gravity produce a complex geometrical effect? What Mass the Earth should have to produce its moon with another diameter? Based on what equation? Let's to consider this question as deep as possible in this paper Gerges Francis Tawdrous +201022532292
