OK... I'm sure I'm going to be kind of yelled at for this, but my dad went and watched some ridiculous documentary on the History Channel about 2012 and a galactic alignment thingamajig and proceeded to freak me out.
I read through a bunch of the topics listed here in previous posts and while I'm mostly feeling much better, I'm a little confused about a few things: Firstly, the Mayan calendar: some posts say that it simply rolls over like an odometer from 12.19.19.17.19 to 13.0.0.0.1 and the '13' can go as high as '19', others say that it 'resets' and the 13 is actually the same as saying '0' and that the cycle of numbers in the '13' position is 12, 13, 1 or 12, 0, 1 depending on your preferred method of display. Which one is correct? :\ Secondly... I've gotten to where all the terms are mixing up in my head, I remember hearing something about the winter solstice lining up with the galactic or celestial equator/plane/longitude/centre. There's some talk in this post of two different alignments - one the z-axis and happening every 30 million years, and one the sun lining up with the galactic plane during the winter solstice (here), and this seems to have happened in 2000 according to other posts. Then other posts talked about a third precession-based alignment that cycles every 26,000 years. And then there's a fourth one that happens twice a year (is this the same as the one from 2000?) Are some or all of these the same and are any of them happening in 2012 (this post seems to indicate that something is?) There's a galactic center, a plane, a longitude... I really can't figure it out. Is ANYTHING close happening at all? Sorry, I know you must get a lot of this (and I have read through the lists and am prepared to be added to it lol!) but I am a bit confused heh. Thanks ![]() |

The long count calendar was used by a number of cultures (so it isn't really correct to call it the Mayan calendar any more than it is to refer to the calendar we use as the Canadian calendar) and over a number of eras. Different people used slightly different conventions when reckoning dates with the calendar. In some examples archaeologists have seen the a piktun is 13 baktun long, so the day after 12.19.17.19.19 would be 1.0.0.0.0.0. In others, it rolls over at 20 so the day after 12.19.17.19.19 would be 13.0.0.0.0. Incidentally, we know this because there are inscriptions that discuss dates well beyond our year 2012, which strongly suggests that the Maya did not believe that the world would end after 13 baktun. |

Bad Astronomy Blog: 2012, the year nothing will happen Universe Today: 2012: No Planet X Universe Today: 2012: Planet X is not Nibiru Universe Today: 2012: No Killer Solar Flare Universe Today: 2012: No Geomagnetic Reversal Whew. That's getting heavy. They've probably all been claimed. Charlatans and fearmongers don't need to focus on accuracy. That's why there are so many versions. Nothing exciting alignment-wise is happening in 2012. Any alignment is the sort that happens every year. Further, alignments don't have any effect other than that 3 moving features happen to lie on, or sloppily close to, an imaginary line, or one moving object passes through an imaginary plane, for an instant. Nothing happens anyway.

If anyone else happens across this thread and decides to start their own anyway--please don't. Please add to an existing thread. Necromancy, in my opinion, is to be preferred to thread overload. Besides, it's not as though all of them are old enough for a revival to be called thread necromancy!

I agree with Gillianren, but only to a point.
We need to seperate the woo threads from the valid information threads. Now; I'm not saying that it's even possible to do that, but there's always hope. And; maybe in 2013 we can close all these threads with a "see? we're still here" post.

Thanks for all the replies and the clarification on the calendar.
01101001 - I did indeed look at the other threads. Most of the time I concluded that nothing was happening, but then I'd run across a couple of posts such as these - Quote:

Maybe a sticky FAQ as has been suggested in many topics would be really helpful... if it just stated whatever alignment you've heard about is nonsense! and started with that, it would take care of a lot of questions perhaps Nevertheless, I am honoured to be added to The List. :P |

That way, the next time someone comes in and says [whatever], we can just say "post #x, here". Of course these would be locked threads to keep them from getting cluttered. Now; the issue is the mods' time.

I am still curious about the longitudinal thing, though (see my prev post) - has that been debunked too or is that what happens every year lol? (just for my peace of mind) |

In reality the sun is NOT moving across the galactic plane. It is the earth moving and near the time of the winter solstice, the earth is in such a place that the sun appears directly in your line of sight toward the galactic plane. The solar system is a long way from literally, physically crossing the galactic plane as it orbits the milky-way. It won't happen for millions of years. |

The explanation is simplified but hopefully not confusing:
The line which marks the galactic plane completely encircles the solar system after all it follows the center of the milky-way and we see some part of the milky-way practically all year around as we revolve around the sun on our yearly voyage (we would see it 365 days of the year if we could see stars during the daylight hours). So, looking out toward the sun and beyond, it would appear that sun crosses the galactic plane not once, but twice each year; every year; as it has for millions of years. Our solar system is not physically passing through the plane, it appears to cross over due to our position with respect to the sun and the plane of the galaxy. ![]() (Image 1: As earth orbits the sun, the sun appears to pass across the line of the galactic center on a certain date) ![]() (Image 2: Six months later, the sun again appears to cross the galactic center, but this time 180 degrees from the first crossing point) As you can see, the sun is not moving with respect to the galactic center, but rather the earth is moving and so appears the sun is moving. The illusion of alignment between earth, sun and galactic center occurs twice per year. Notes: 1. The galactic plane is tilted a little more than 60 degrees from the ecliptic plane. |

I have no idea what is meant by "galactic longitude". The circle of the earth is divided into longitudinal lines (meridians) with zero degrees being the imaginary line that passes through Greenwich, England. The eclipic is divided into longitudinal measures, with zero degrees being the line which passes through the spring (vernal) equinox. The galactic plane is divided into longitudinal measures with zero degrees being located in Sagittarius (the center of the galaxy). Maybe they are making a big deal because the sun appears to cross the galactic plane very close to the galactic zero longitude. All of these lines are more or less arbitrary - agreed upon by astronomers and navigators as points of reference.

Sorry, I promise this will be the last clarification needed, I'm just trying to figure this out. I can't quite get my head around all these planes and things (the scale is too big. I work better with lattice planes... :P) |

It happens every year. In fact in some years past, the alignment with the galactic zero longitude has been even closer to the exact date of the winter solstice than it will be in 2012. The timing of the crossing varies slightly year by year.
As for visualizing it - download a good planetarium program that will let you turn on the line of the galactic equator and the line of the ecliptic. For example, here is a screenshot from one such free program available on the internet: ![]() (The plane of the galaxy - line seen slicing through the center of the milky way - is being crossed by the sun as it travels along the line of the ecliptic. date 21 Dec 2012 - approx 10:30AM) The program is Cartes du Ceil (Sky Charts). I only recommend it because it is accurate and free, there are others that work as well. Download Cartes du Ceil here: http://www.stargazing.net/astropc/ Signing off for the night, kabutar |

OK, I've gotta admit the star charts mostly go over my head and I'm still confused as to what exactly is what, but thanks for the visual, it does help a bit. I think the most important thing is that no alignment - equator, ecliptic, longitude, center, plane, etcetera! is happening in 2012 as mentioned above, lol.
Thanks again for the help ![]() |

Well then how about thinking about it this way.
The galactic plane is simply a description of a geometric thing. It is fundamentally no different than the equator of earth. What happens to you if you cross the Equator? Nothing much. Similarly, for the galactic plane. What happens when you cross it, nothing much. These are lines which we simply make up to give a frame of reference to reality. Since they are geometric constructs, crossing them has no 'meaning' as such apart from describing our position relative to other objects.

By sheer coincidence this date also happens to be when the Mayan calender rolls over, or whatever it does. There exists no known physical process which could affect the Earth in any meaningful way on this date. If something does happen, it would be, for lack of a better word ... magic. If you believe in magic, you should probably stock up on bottled water and canned goods. Otherwise, don't sweat it. |

formulaterp - yes, sorry, that too, but if it happens every year it's nothing to worry about. Hence my meaning that there's no 'special alignment' in 2012. The only reason I kept posting was coz I was trying to understand what they meant by 'galactic longitude', which seems to be the sun between Earth and the center... so all good.

http://en.wikipedia.org/wiki/Image:2...-annotated.jpg You will see that 0 deg longitude points toward the center of the galaxy. This is of course an arbitrary choice, like 0 deg longitude on Earth runs through the Greenwich observatory in England. |
