Extra gas giants

LB, If the problem is models how would replacing them with other models be helpful? We have a fundamental error that needs fixing. No one even sees the error which is not even that difficult to grasp. It has to do with where mass centers and gravity are located in the real world vs where models locate these two centers. This effects almost everything theory predicts. A simple statement I have made many times for at least 15 years about this has been lost in the drivel I assume. Anyway, if you properly locate these two centers a lot of confusion is removed.

OK.

Q1) Where do the models say they are?
Q2) Where are they in reality?

The model says they are the same thing. It is the Kepler model as designed by Newton 300 years ago. It works wonderfully for predicting everything about a gravity system as long as most on the of the mass of the system can be assumed to be located at one point such as the center of the sun. In reality this assumption leads to error because the mass of any system is always distributed throughout the system such as a sphere like Earth or disk like the Milky Way. When the two centers are seen as different and not located at the same place the model changes radically and a lot of new information comes into view much like a lifting of the fog in the morning.

There is more than one model. (Kepler, Newton, Klum, Ptolemy, Brinkley, Einstein, Brahe ...)

Some models are more detailed, more ... intricate ... than other models. And each model is typically used under different circumstances than the other models.

Some of them assume that the mass of an object has a non-spherical distribution. Some even allow for an object to have a totally arbitrary mass distribution. But the most useful models take advantage of symmetry as much as possible to reduce the cost of calculation.
