Regner T I do not support Geocentrism -- I do support Heliocentrism. These two theories are mutually exclusive -- if you prove one, you disprove the other. Note however that disproof of one does not prove the other. I offer five propositions which suggest to me that the Heliocentric model offers the more accurate explanation. 1. Kepler's three planetary laws explain how the Solar System works and satisfy observation; 2. Newtonian physics explains why Kepler's Laws work; 3. The observed behaviour of gyroscopes et al is adequate demonstration that the Earth rotates on its axis; 4. The observed six monthly variation between red and blue shift of stellar spectra is adequate demonstration that the Earth revolves around the Sun; 5. When appropriate allowance is made for the Earth's rotation and revolution, various endeavours succeed. These include - a. Fuel estimates for satellite launches are adequate; b. Ballistic missiles and artillery shells hit their intended targets; c. The exquisite precision required for successful inter planetary navigation is achieved. Paul D Sick of deleting your inbox?
