BIG BIG DIFFERENCE in that you can examine the ENTIRE behavior of
objects in trajectories on Earth, and thus fit the limited view
you have of any given trajectory into a known pattern. There is
NO comparison here, as the turnaround of comets out in space,
outside of your view, is a COMPLETE UNKNOWN!
We beat this to death over a year ago on this message board, in the Re: Ephemerides - the Zetas Explain thread. Bottom line, you have the comet entering at point A, circling around the Sun and leaving at point B, then going out into space and SOMEHOW, magically, moving from point B to point A again for a re-entry into the Solar System. The explanation given is that it forms an ellipse, which is a DESCRIPTION of what you are viewing during the limited time it is in the Solar System, not an explanation. The fact that planets or objects orbiting the Sun form circles or ellipses does NOT translate, as at all times these bodies have the Sun to their side. The comet, shooting AWAY from the Sun, has more pull backwards than sideways, in the extreme. So why would it move to the side, dramatically, from point B back to point A?
The current explanation for comet behavior doesn't even take
into consideration recent evidence that comet orbits form more of
an ice cream cone shape that an elliptical shape. This gets
published and promptly forgotten, as the adjustment in thinking
give astronomers a headache. So much more comfortable to cling to
the old and familiar, and then there's the issue of challenging
your gods. So logic goes out the window, and pig-headedness
reigns.
