Yes, because of precession, mostly (our motion through the Galaxy is very slow, relatively). That's why the celestial (RA/Dec) system changes with "epochs." The galactic system, not so much.
While this is no doubt true as of the instant in time the page was written, those coordinates will change over time.
Were the Maya here 30 million years ago, when we passed through the actual plane of the Galaxy? Or are you talking about precession? Which has nothing to do with our location in the Milky Way.
And if that is true, would it not be possible that others may have been aware of such cyclic changes by observing them and the heavenly correlations over an extended civilization?

Actually, precession is more than a "visual phenomenon," it is a the physical movement of where the Earth's rotational axis points. But I suppose, in your terms, that the Sun crossing the galactic equator twice each year is also a "visual phenomenon only."
You seem to think the only two perturbations in the solar system's orbit in the Milky Way are due to this 30 million year cycle and precession (which is not even related; it is a visual phenomenon only). Do you have a link to show there are definitely no other perturbations in the solar system's orbit?

Are you saying that the gravitational pull of the moon is different during a full moon?

You're asking for a link for a negative? Would you like one that says there are definitely no unicorns too?
I thought it was the galactic plane. How many planes does the galaxy have, do you think? Did you mean astral plane?
I suggest that may be due to the Mayan claim of crossing a galactic plane wherein such conditions exist.
(Which it didn't, btw. It crossed the galactic equator, just like always. Twice, each year.)
But the change in the case of the Mayan calendar coincided with the exact moment the sun crossed the midpoint of the galactic plane,
How many planes does the galaxy have, do you think?
But you were talking about one, in particular, in the OP.
I don't think; I know. Any 3-D region has an infinite number of planes.
Hardly. I'm pointing out, as have others, that using the Mayan calendar and the solstice of December 2012 doesn't really add much credibility to your hypothesis. It is you who "confused the concept" by making that 2012 nonsense integral to your argument. GIGO.
You seem to be more intent on trying to confuse the concept than consider it, Phage.

I do not know when the Aztec civilization (which is where much of the Mayan calendar was derived) was here, although I would estimate they appeared less than 30 million years ago. However, the Maya do not speak of a 30 million year cycle; they speak of a 26,000 year cycle, and it is that cycle we are discussing.
