To provide an interpretation of Nature that makes sense, is comprehensible and unified.
Because theoretical physics doesn't make sense, is incomprehensible and has no unified theory!
Below is an example of physics incongruity.
The ambiguity of physics' space-time curvature... And a clever, yet simple solution!
Space time curvature's traditional analogy
Space-time curvature is most often compared to the deformation or curvature of a thin sheet of fabric such as a depressed trampoline in the middle of which a child just landed. In this analogy the sun creates a curvature of space-time in the same manner as the child stretches the trampoline’s fabric.
Then the earth is deviated by the curvature of space-time, as a marble would be by the slope or the curvature of the trampoline around the child.
Physics space-time curvature is not up to par!
In the analogy, the trampoline's fabric interacts with child and marble because that fabric is material.
In the solar system, unfortunately this is not the case: while earth and sun are material, man-imagined space-time is not!
How do material and immaterial interact?
In the next paragraph is an alternative to physics' hard to believe type of interaction!
Gravimotion's logical alternative
Taking the analogy that is reality at face value: all participants are of same type in the analogy!
Because the sun's induced space-time curvature is definitely the cause of earth's motion around the sun, that curvature has to interfere with earth's own surrounding space time and not with earth's mass as believed in physics. Now the participants in Nature's show, in the reality of the solar system are of same type.
In the Gravimotion interpretation of nature, gravimotion's equivalent of earth's own space-time (and NOT earth's mass) overlaps and interacts with the sun's space time equivalent.
It turns out that such a minor modification in the basic assumption we human make of the phenomenon has dire consequences on the laws of physics! In short, these laws are designed after an "unfounded" belief; another option that of gravimotion's may as well be chosen; and physics' actual choice might not reflect the "nature" of Nature
By the way, in gravimotion that equivalent to physics' space-time is not mathematical but physical!

Physics remains nevertheless true to its mission
While stating that space-time-curvature/matter interaction does not make sense catches the attention, that might be irrelevant!
Physicists as far back as Newton clearly stated that the purpose of physics is to describe and not to explain.
The primary goal of physics is to describe, not necessarily to make sense! And this is not specific to physics. Think of Picasso's description of Nature.
