The helical model - our solar system is a vortex (our Galaxy, too)

22. But there are things like the 2nd video's invocation of 'precession', which is totally wrong

Precession is about the change in direction of the earth's rotational axis (which is what has a 26,000 year period, a figure the video gives, but for a non-existent spiralling of the sun in its path around the galaxy - as if there's a large concentrated mass the sun is orbiting, but which itself orbits the centre of the galaxy); or the change in the direction of perihelion/aphelion - again, for the Earth.

'Spiral' can mean a path going closer to a centre, as well as away from it.

My GGG-father relied mainly on the bible for his 'proofs'; occasionally a misunderstanding, and sometimes pure fantasy; such as a 'fact' that it's more than twice as far to go round the Earth at 50 degrees south as at 50 degrees north - he though the earth was a circle, with the north pole at the centre. No-one had reached the south pole when he wrote it, but presumably he would have accused them of lying if he had heard the claim; as he had to believe navigators had been doing for several centuries. And that's rather like this case - there are many astronomers who have been checking the movement of the sun in the galaxy for decades, and it's really not the kind of thing they could all be getting wrong without reputable astronomers having figures to disprove them.
