Because it lands on irrational grounds the quantum theory doesn’t make sense. The results of the mathematically rational theory are "irrational". The theory for instance cannot predict through which one of two slots a particle will travel.
Now the question is: Is the irrationality of the theoretical results due to the nature of Nature or due to an unsuspected fault within the alleged "rational" theory?
The fact that physics laws (due to the results of the theories) make no sense drove this writer into distinguishing these laws from reality. Reality has to make sense.
The conclusion is that somewhere a "fault" (or more than one) lies within the theory.
This in spite of the fact that the theory is "faultless"!
Amazingly there is a solution to this dilemma!
This writer discovered an arbitrary assumption at the very base of physics' theory!
That arbitrary assumption, being "assumed" or "taken for granted" before any equation of physics is introduced doesn't in any way jeopardize the validity of the mathematics of the theory!
Physics mathematics remain "fautless"!
Yet, because the starting point is questionable, in spite of the fact that the theory is fautless, the results of the theory are questionable!
Then one has to start over and lay down an alternate theory; this writer offers an alternate called the gravimotion mechanism or theory.
In the eyes of this writer, there is another split, now specifically between Nature and the quantum theory, that mandates an alternate.
