 Gravitational Theory and Resonance 
  For example, a parameter that defines the direction of the long axis of the Earth's orbit, called the line of apsides, is known due to Fourier Analysis to currently be very slowly revolving eastward at a rate that would take it about 108,000 years to entirely circle the orbit. 
  By applying standard forced vibration theory and resonance theory reasoning and equations to the explanation of the perturbations of these several situations, it seems that a logical theoretical basis may exist for explaining the phenomena. 
  I believe that, given the equation of standard Newtonian gravitation and the ones for forced vibration, and applying them to the group of the four large moons of Jupiter, a longterm computer simulation, beginning with four random distance moons, would eventually result in, and therefore "predict" the currently seen metastable periods for each of them.
