End of the world in 2012?

Revelation 1: “Galactic Alignment”

The Mayans predicted that on December 21, 2012 the Sun will receive a strong synchronizing beam coming from the center of the galaxy, which will change its polarization and produce a gigantic radiant flare»
* extracted from the supposed 7 Mayan prophecies.

This scenario predicts that the Earth will will align with the center of the galaxy on 12/21/2012, an event that only happens every 26,000 years andqthat will trigger a catastrophic event. Well: 26,000 years (more precisely 25,800) is the time it takes for the Earth's poles to describe an entire circumference in a movement of precession. The effect What this has is that every 2,150 years (1/12 of 25,800) a zodiacal constellation moves with respect to the ecliptic, until after 25,800 years the cycle is repeated. So, the only thing that the phrase "means"Every 26,000 years the Earth aligns with the center of the galaxy", is that every that amount of time the Sun passes through Sagittarius again (where the galactic center is located), in the same specific period (in this case, between mid-December and mid-January).

But, since the precession is slow, both in December 2009, 2010, 2011, 2012, 2013, 2014, etc., the Sun will continue to "aligning with the center of the galaxy"because it will continue to pass through Sagittarius. And if we go back to before 2,150 years, the Sun will continue to "aligning with the center of the galaxy» at some point, one or more months behind December-January, depending on how far back we go.

I took the trouble to make a sequence of diagrams (figure on the right, click to enlarge) showing the positions of the Sun on 12/21, between 2009 and 2014. The first noticeable detail is that the apparent position of the Sun on 12/21/2012 is not exactly "aligned" with the galactic center (located at coordinates A.R. 17h 45m 40s and DEC -29º 00' 28'‘ [Epoch J 2000.0]), but by about 6º, and 2012 is not even the year of smallest angular distance from that center, but 2021, according to the described trajectory. This shows how absurd it is to look for alignments based on something as insignificant as angular distance, which is nothing more than a game of perspective depending on the position of the observer. If we omit this factor, "aligning ourselves with the galaxy" would be as simple as pointing a line to the galactic center, on any date we want.
