The only acceptablle,do you hear this,the only acceptable view of the event is that the faster orbital motion of Venus overetakes the slower orbital motion of the Earth with the central stationary Sun as the backdrop. The reason astronomy does not exist for the rest of humanity is that very feebleminded people who treat astronomy solely as an exercise in magnification cannot rise to the level of intutive intelligence which was present in astronomers 500 years ago.The event where the faster orbital motion of Mercury overtook the slower orbital motion of the Earth last November barely was heard as a news item because the only authority availible describes it as a planet passing against the Sun with no mention of the Earth's orbital motion.

It will be a once in a lifetime event for people insofar as that orbital event in 2012 will be the first time it will be presented as an affirmation of Copernican reasoning based on orbital comparisons.The faster orbital motion of the Earth accounts for the slower forward motion of the outer planets in our common heliocentric orbits while the contemporary affirmation of a common heliocentric orbit using the inner planets should have been these 'transit' events.Neither Copernicus or Kepler would have telescopes to affirm heliocentricity this way but modern imaging can. The truly horrific destruction of Western astronomy is due to the inability to correctly identify that the faster orbital motion of the Earth overtaking the slower outer planets accounts for a common heliocentric orbital motion - http://antwrp.gsfc.nasa.gov/apod/ima...2000_tezel.gif " For to the earth planetary motions appear sometimes direct, sometimes stationary, nay, and sometimes retrograde. But from the sun they are always seen direct," Newton Looking to the outer planets Copernicus accounedt for heliocentricity that way and using the faster orbital motion of the inner planets and the transits the modern viewer can now account for heliocentric orbits by this means.The dominant and useless contemporary view you originating with and only with Newton,you can do nothing with - " For to the earth planetary motions appear sometimes direct, sometimes stationary, nay, and sometimes retrograde. But from the sun they are always seen direct," Newton Go ahead and try and defend the stupidity of Newton,it means that another generation will be denied the appreciation of Copernican reasoning. |
