Neville if you now doubt the OT as being the inerrant word of God, does this then mean that you no longer are certain of the geocentric position? Some time back I wrote of the impossibility of a stationary non moving platform away from our solar system to observe whether the earth rotated or not. I said at the time one would have to be with God. I am now not so sure. Around the same time we discussed the effect of the earths rotation on a satellite launched from the pole.. Remember we agreed that it would have an angular rotation of its own equal to a 24 hr period. However on a rethink, I went back to polar orbiters launched from the equator.. I previously assumed that such an object, in addition to its angular rotation pole to pole , would have as well an axial rotation equal to that imparted by the rotation of the world. counting all losses of course. Yet such would seem impossible.. A polar orbiting satellite like any rotating object would inherit the stabilising force of that of any flywheel, and would eventually and quickly lose any axial rotation given to it at launch from the alledged earth rotation. As it rotated pole to pole, it would be the proverbial static platform relative to the E-W plane of the earth. Also ditto relative to the annular movement around the sun, but that is ignored here for this discussion. From this it must be concluded that if the earth was stationary, with no daily rotation, the polar orbiter would traverse the same meridian every orbit, continuously. However if there was any rotation of the earth from west to east, and let us assume for simplicity a 120 minute period of the satellite , it would traverse a different meridian 30 degrees apart towards the west every orbit. It remains for us now to investigate any of these satellites that exist, and their plotted courses if such exist.. Here is one for you to digest. They called it sun synchronous, and I do not know exactly what that means... If they mean the plane of the orbit always points to the sun, then that for the reasons above is impossible. However they may mean it is static relative to the sun in the same way that the inclination of the earth is.. It seems from the evidence below, on the basis of normal physics the earth rotates. # http://ww2010.atmos.uiuc.edu/(Gh)/guides/rs/sat/poes/home.rxml Image provided by: Satellite Coverages and Orbits (NCAR) The POES orbit (above) relative to the Earth's surface is sun-synchronous. Its track is due to a combination of the orbital plane of the satellite coupled with the rotation of the Earth beneath the satellite. The orbit is slightly tilted towards the northwest and does not actually go over the poles. The red path follows the earth track of the satellite, the transparent overlay indicates the coverage area for the Advanced Very High Resolution Radiometer (AVHRR) imaging instrument carried by NOAA/POES satellites. This instrument scans a swath roughly 3000 kilometers wide. Philip. # Of course normal physics must be wrong as they do not accept the aether...
