Delusion
Basic problems with the knowledge of the solar system deal with what makes the planets rotate and orbit, what makes them do so in the same direction and what makes them do so on a plane horizontal to the axis of rotation.
No theory of solar system movement takes into effect the movement of the sun. Proponents of the big bang hypothesis that substitutes incomprehensible beginnings for an incomprehensible god are ignorant of the effects of the movement expansion requires on the dynamics of the solar system because if the sun moved at the rates required by the big bang, the sun would be going faster through space than the planets move around the sun.
The matter of solar system movement is complicated by the fact that the planets move with the sun and therefore have to be connected to the sun by a current force, something for which no theory presently accounts.
The sun's speed and direction, however, can easily be determined by a high school student using homemade measurements or measurements obtained from an almanac. The reason it is not done is because the mass/gravity concept, and its add-on, the space/time conundrum, and the belief that the planets speed up and slow down as they move around the sun obscures simple, measurable reality.
The belief that the planets speed up and slow down without a current force affecting them is based on kepler's belief that tycho brahe's observation that the moon sped up in the summer and slowed down in the winter was based on the conclusion that the distance over which the moon traveled during both periods was equal. Because the distances are not equal, the sun's motion changes the distance in summer and winter, the speed differential is simply an optical illusion based on the mathematical reality that, with equal distances, the rate had to be changing.
The reality is that, because it takes longer for the earth, the only planet whose movement we can accurately measure, to move between the summer and winter solstices than it does to move between the winter and summer solstices, and because the distances over which it is doing so are not equal as a result of the sun's movement, we can easily compute the speed at which the sun is moving as well as the direction in which it is moving.
The objections to the proof are that the sun is stationary in space, universally thought to be an absurdity, and that some unknown force is affecting the movement of the sun and planets so as to neutralize the computation.
Adding unknown forces to explain a reality that doesn't exist based on a theory that has no explanation for current force is the common practice of a system of knowledge-seeking that has become so corrupt as to create a delusional system for which proof is nonessential, a system in which belief has to be maintained at all costs.
The fact remains, however, that the measurements contained in the proofs, even though they negate mass/gravity, and all of the empirical structure of unfounded beliefs that have been mindlessly built upon it, remain unchallenged.
