Missed it by that much.

I see what looks like a vivid imagination going off on flights of fancy with contrived attempts at analogies.

Thanks Grant – so if you added the galactic centre to the 2012-12-21 picture it would not be right behind the sun?
|
Not even close. The galactic center is some 5 degrees from that intersection. See my remarks further down the page.

Thanks Hornblower. It seems the close alignment between the solstice meridian and the galactic plane may have led some to confuse them with each other. For example, on this picture of 2012, is it right that the diagonal line marked ‘galactic equator’ is close but not the same as the solstice meridian?
|
Not even close. The solstice meridian would be straight north and south, with the galactic equator inclined about 27 degrees counterclockwise.

Thanks again Grant, so this part of the theory, ie galactic core moving galactic planar hemispheres as viewed from earth, is incorrect. Yet, as I understand it in line with Hornblower’s comment, the conjunction between the solstice and the galactic core does occur in 2012, does it not?

Once again, not even close as I interpret it. First, let me remind everyone that I stand corrected by Jan Meeus's finding that the solstice crossed the plane in 1998. That picture shows the 2012 sun slightly to the right of the galactic plane. I don't know whether or not that was intentional, but it is in good agreement with Meeus.
As for conjunction with the core, I would interpret that as the minimum separation of the solstice point and the core, which is some 5 degrees south-southwest of the current solstice point. That will occur roughly two centuries from now. See this link for the coordinates of the core.

Astromark, no I am not looking for something that is not to be found. I don’t find your comment ‘those lines are not there’ easy to understand. Thank you for the lesson in existential philosophy, but the lines are there in the picture so presumably they reflect an astronomical reality? Lines such as the ecliptic and the meridian indicate how our earth stands in relation to the cosmos. Does not this indicate they are really there?
I think the significance of this event is that the luni-solar 25765 year long precession of earth’s equinox means the December solstice will precess past the galactic core in 2012. It is true that the movement of the galactic core against the galactic equator has a roughly similar cycle?

What cycle are you referring to?

If so, a fifteen year gap between the two events is fairly close.
