However, it will take 36 years for the December solstice sun to completely move past the Galactic equator during the precession. The first part of the 36 years of the earth's precession on it's axis, will be the 18 years before when the sun begins the journey across the galactic equator to reach the point where it's center is on the galactic equator. In , the precise alignment of the solstice point the precise center-point of the body of the sun as viewed from earth with the Galactic equator had occurred.
Then, the remainder of the 36 years will be the 18 years of precession after , i. So at the moment, part of the sun during December is still on the galactic equator. It takes 36 years from to for the winter solstice sun to move past the galactic equator during the earth's precession on its axis.
Every year, precession pushes the Sun's position a little way further through the Milky Way. Since the width of the Sun causes an imprecise alignment to still be a visual alignment, there is a Galactic Alignment "zone" from to The galactic alignment in question does not exclusively happen on December It takes place over a 36 year period, corresponding to the diameter of the Sun, with the most precise convergence having already occurred in Therefore, it is being said that after , we will be seeing the last part of the galactic alignment until Scientists say we may not actually experience the effects of the galactic alignment until later, during the end part of the galactic alignment from to Researchers are giving another 3 years until or for the destructive events to happen and for the possibilities that it might take that long to really come out of the effects of the galactic alignment.
It is being said that it would be after 21st December that earth might be badly affected because:. The place where the alignment takes place is where the 'nuclear bulge' of the Galactic Center is located. Astronomers refer to the 'nuclear bulge' of the Galactic Center as the center of our Milky Way galaxy.
The Milky Way galaxy looks round from the top. However, from the earth, we always have a view of it's side where the centre is thick and the edges are thin and long.
Thus, it can also be said that the alignment in is an alignment between the December Solstice Sun and the Galactic Center. However, since the nuclear bulge is quite large, it is more precise to say that the alignment of the December solstice sun is with the Galactic equator. Thus it is being said that the point of the December 21 crossing is not at the center but is only close to another point in the Milky Way galaxy called the "galactic center". The sun is not going to go through the black hole which is in the exact center.
The sun never gets any closer than about 6 degrees away from the galactic center. Six degrees is roughly 12 times the diameter of the sun as seen in the sky. Some say that this is not close while others say that it is considered close when the earth' axis is also near the galactic equator at that time with it's axis pointing to the center of the black hole as during Some scientists say that being near the black hole of the Milky Way with the earth's axis situated near there is by itself also a dangerous situation to be in.
There is another aspect to the galactic alignment where another very different kind of galactic alignment is proposed by some scientists. The is said that the solar system moves above and below the plane of the galaxy very slowly vertical oscillations while the sun obits around the galactic center. The Precession of the equinoxes: The earth wobbles very slowly on its axis and this causes the position of the equinox to shift backwards, or precess, through the signs of the ecliptic at the rate of one degree every The full precessional wobble is complete in roughly 25, years.
The vernal equinox point is defined by the intersection of the ecliptic and the celestial equator. The Celestial Equator: The earth's equator projected into the stars. It is the plane of the earth's rotation. The Cross formed by the Milky Way and the ecliptic: Exactly as stated. There are two of these, one in early Sagittarius, the other in early Gemini.
The former cross has the virtue of being located within the nuclear bulge of the Galactic Center. The more precise and abstract center-point of the nuclear bulge is the precise Galactic Center, located at about 6 degrees Sagittarius sidereal and 27 degrees in the tropical zodiac. Additional Glossary of Mayan Calendar terms. We can have a more general discussion of galactic alignments in history if we consider that the solstice axis aligns with the galactic equator every half precession cycle.

Note that the claims are not being made by Maya people themselves. The Sun is but one of a few hundred billion stars that make up the Milky Way Galaxy.
The Milky Way Galaxy is shaped like a disk with a bulge in the center. The disk is about , light-years across and 1, light-years thick. Remember, a light-year is the distance that light travels in one year it is not a measurement of time, but of distance. The Sun is located about 30, light-years from the center about halfway out. The Sun moves in a roughly circular orbit about the center of the Galaxy the fine details of the orbit are pretty messy , taking about million years to complete one trip.
Since we are located inside the disk of the Milky Way, we do not have that outsider view of it. Here on Earth, we see it as a band of hazy light running through the sky with dark rifts inside it.
From this perspective and using only the unaided eye, it is difficult to discern its center. But with modern tools like telescopes that can see infrared and radio light, we now know that the center is located in the constellation of Sagittarius which is most prominent in the summertime sky in the Northern hemisphere. At the center of the Milky Way Galaxy lies a black hole with the mass of millions of Suns. Note that this model is stuck to a stand and viewed at two different angles: mostly face-on top and edge-on bottom.
This image was constructed from infrared data collected by the 2MASS project. Infrared light passes through much of the dust in the Galaxy allowing us to see more of its structure than we can with our eyes. Alignment With the Galactic Center.
When people talk about alignments we need to be clear.
