   The _Titius–Bode_ law (1766/1772) was proposed much later than Kepler (16th   
   century), obviously.  And to date nobody understands why it approximately   
   works for the Sol System:

   Yes, Kepler's idea was that the "harmonics of the world" would be   
   represented by inscribed Platonic solids to determine the distances between   
   the orbits of the Planets.  However, he was scientist enough to accept   
   eventually that, given Tycho Brahe's detailed observations, the circular   
   orbits that resulted from that would not work: ellipses were required.

   Doubtful.  Kepler was a devout Christian who sought to discover/understand   
   "God's design of the Universe".

   What is that supposed to mean?

   Only approximately, and that is where General Relativity fills the gap in   
   our understanding.  So far, only GR can explain, and predict very precisely,   
   the additional motion of the perihelion of orbits as, 200 years after   
   Newton, eventually become measurable with the orbit of Mercury.

   Nonsense.

   Pseudo-scientific word salad.   
      
   Sadly, your mind is still very confused.
