The geocentric model, or Ptolemaic system, placed Earth at the center of the cosmos, with the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn, outwards in that order, as planets ("wanderers") orbiting our world.  Claudius Ptolemy, a second century A.D. scientist and writer from Alexandria in the Roman province of Aegyptus (modern Egypt), worked on and presented a model of the universe's structure which lasted as an accepted viewpoint among the educated until the Renaissance.  That a brilliant man could be so wrong attests less to his greatness as a thinker, and more to the lack of proper equipment with which to observe the sky.  In 1610, Galileo Galilei pointed his (by modern standards) low power telescope at Jupiter and saw points of light moving around the planet that had, even then, an oval spot.  Concluding he was looking at four moons orbiting another world, he saw that Planet 6 (Jupiter, in the Ptolemaic system) had its own moon system, making the universe far more complicated than Catholic officials, for reasons of integrity, could admit, as they, according to the popular story, refused to look through Galileo's telescope at worlds we now call Io, Europa, Ganymede, and Callisto.
     "Nevertheless," Galileo reportedly remarked, "they are there."
     Orthodox views often shut out the new.  I'm amazed by how the vastness of the Christian universal viewpoint (God created everything) will at times refuse to learn or care about what the universe really is, how it's about 13.8 billion years old, how it expanded outwards in a cataclysmic explosion from a single point smaller than an atom.  That there are neutron stars, gamma ray bursts, black holes, colliding galaxies, another possible planet in our Solar System not known about before this year.     Ptolemy's model has been overruled, and even most Christians don't believe there are just seven planets in our system.  Discovery of gravitational waves resulting from a collision of two black holes 1.3 billion light years away (1.3 billion years ago, in other words) have verified Einstein's equations on the matter.  We're inhabiting an alive, moving system of universal proportions.  Applying static theories to it makes for interesting-looking models, like the brass articulated sculptures of the Ptolemaic system--beautifully made, shiny, but hard, stuck in a past set of views no longer relevant.
     If God created everything, surely that being could contain all current human knowledge and what will come of our development beyond now.  God is what we haven't yet thought about.
