If a galaxy has no real equator, why they say the poles of sun will change if sun was above or below the equa-?
If a galaxy has no real equator, why they say the poles of sun will change if sun was above or below the equator? My perception of a galaxy is a mass of stars and planets in several systems like our solar system, circling around a center. This mass is not a whole body like a planet or a star; therefore, it doesn't have magnetic poles like the sun or the earth, right?
My question is that, if the Milky Way galaxy doesn't have magnetic poles, it can't have a real equator, and north and south hemispheres like our planet. But why they say that when the sun passes the hypothetical equator of the galaxy, the poles of the sun and all other planets in our solar system will shift and become upside down?
What's the relation between the galactic equator and the magnetic poles of the sun here? I don't get it! Even if Milky Way galaxy actually had magnetic poles, I doubt if it had any effects on this particular issue. I'm neither a scientist, nor an astronomer, but logically I can't imagine any exceptional phenomenon can happen if the sun passes the galactic equator or not...
Mark G, I've heard many opposing words; some say that cycle takes millions of years, some say it takes the full period of Mayan calendar which is about a few thousand years, and you say that it happens every 22 years.
I'm really confusing these numbers...

You are right to be suspicious.
There is probably an overall galactic magnetic field, I would not actually know if it is strong or weak, it would be the sum of all the field generated by various bits and pieces in the galaxy. Stars, planets etc. Since the individual fields are pointed every which way, the overall field is likely to be small, much smaller than the local magnetric field of the Sun or the Earth.
"But why they say that when the sun passes the hypothetical equator of the galaxy, the poles of the sun and all other planets in our solar system will shift and become upside down?"
They're lying. That's all. It's part of the great 2012 rip-off of the gullible. There is no relation between the galactic equator and the magnetic field of the Sun and there is no relation between the galactic equator and the magnetic field of the galaxy, just as there is no relation between the magnetic poles of the Earth and the equator of the Earth, they are entirely separate things. And as far as it known, the solar system passed through the approximate position of the equatorial plane 3 million years ago and we will not be back for another 30 million. The entire thing is doubly, triply irrelevant.
We don't actually know exactly where the galactic equator is to within a few light years, any estimates of where it is are only estimates and it is not of any importance. The supposed galactic equator is not related to any magnetic field the galaxy may have, it is related to the distribution of stars and other stuff in the galaxy. It is just an imaginary plane through the galaxy such that the mass of material on one side is the same as the mass on the other.

This is kinda hard to explain without me having to hold the Milky Way in my hands. Let's ee how I can substitute divine powers with your imagination...,
First off, there is no truth to "If a galaxy has no real equator, why they say the poles of sun will change if sun was above or below the equator?"... That is pure nonsense. Let's break it down. The Milky Way is spiral galaxy so it assumes a form of a disk. Like every other object, you can divide it by half and since we are referring to an "equator", we should disect it in a way parallel to the disk itself. This imaginary line should be the "plane" of our galaxy. This is where the Sun traverses our galaxy. The sun traverses this orbit around the galactic center in a way that is bobs up and down from the plane. It is never always on the plane, for short. According to the 2012 hoax, if the sun crosses this plane it will align with the galactic center and according to another BS you heard the sun's poles will shift. Hahaha! You see, that is pure nonsense since there is truly nothing special while crossing the galactic plane. Like the rest of the galaxy, it just happens to be there. The sun moves up and down the galactic plane in a 3-million year span stretched over a longer 70-million year wave. If you have seen a wave or a waveform in an oscillocope, that motion can be compared to smaller waves on top of a larger yet more expanded wave. Of course, the motion looking from a vantage point above the galaxy is somehow (but not perfectly) circular. Of course, in space there is no up and down so technically, the sun can be in only one side of the disk.
Okay, next one. The Milky Way does not affect the sun changing its magnetic poles, period! The sun is basically changing its magnetic poles every 11-years which happen to coincide with the solar cycle. The solar cycle being the period of greatest magnetic activity in the sun. It happened last 2001-2002. So according to your age, you can count how many times it already happened and from that know that you are still here typing your curiosity into Yahoo! Answers.
See, there's nothing to be confused about...

Who exactly is "they"? The sober serious scientists that I read, such as David J. McComas, Eric Christian, N. A. Schwadron, M. Gillman, H. Erenler, and many others, say nothing about the poles of the sun changing just because the sun is above or below the galactic equator.
The sun changes its magnetic poles every 11 years. It crosses the equator every 35 to 40 million years.
And yes, the galaxy has a magnetic field, of about 0.5 nT. The sun's field is about 150,000 nT.

a great style of human beings have reported that that is because of the fact the earth is tilted. yet i'd could ask them if it may well be any different if the axis became into completely perpendicular to the ecliptic. The equator would get carry of *extra* photograph voltaic if that have been the case. The equator is the line on the earth the place the sunlight shines maximum quickly a great style of the time. that's halfway between the northernmost and southernmost extremes of the sunlight's obvious music in the sky. this would be real inspite of the degree of tilt. the lean isn't the main clarification for the equator receiving extra photograph voltaic. that is not because of the fact the equator is closer to the sunlight, the two. the adaptation in distance is negligible.

The really question is who is "they" and it turns out that the "they" are people who don't know what they are talking about. It doesn't happen like that.
In fact the magnetic field of the sun reverses every 22 years as part of the sunspot cycle.
