"why and how spiral motion causes precession". |
Hello bojan,
Bojan,
Yes we can see that the protection of the medieval perpetual solar system notion has got deeper and deeper and more complex since the 17th century . I take it this is your reply to my question, that “if you consider there is no such thing as spiral planetary motion, what do you think the motion is? Then your response now is that, there is such a thing as spiral planetary motion, “open and closed” spirals but that spiral motion, is a highly complex motion. Well at least you have answered the question, you believe there is such a thing as spiral planetary motion.
Your question to me was for an explanation.
I have posted the first part of my explanation to you and will continue probably today.
As I see it, the situation at the moment has advanced, most agree that there is such a thing as spiral planetary motion. The difference of opinion now lies in whether it is a relatively simple movement of our spheres or; is a highly complex movement, a movement that prevents science discerning whether our planet is moving progressively and continuously, albeit slowly changing our angle of obliquity.
That then is your task, to maintain this situation of no advance beyond the medieval notion of an ‘invariable’ solar system; that our axis is merely wobbling back and forth over a 2.4 degrees cycle over 14 thousand years. Over the past 360 years there has built up a vast array of ‘proof’ to defend this. You have plenty of ammunition, we know.
I do wonder how any modern astronomer can be happy with the accepted theory of the ‘invariable’ solar system without question
Can you explain what a ‘closed spiral’ looks like please. A simple sketch would be better.
