And it's basically the change in the axis of the Earth relative to the equator of the sun or the ecliptic plane.

So if you project out the equator of the sun where all the planets are orbiting, it's the change in the Earth's tilt relative to that plane, the obliquity of the ecliptic.

And so on that cycle, it's a 41,000 year cycle, turns out that he dated it using the star charts of the time at around 15,000 BC.

Now, his work was validated in the early 2000s by the Bolivian – this is a funny story – Bolivian head of archaeology in Bolivia and these astronomers that went there and said, let's check Poznanski's work using the astronomical almanac, more up-to-date information.

And they said, yes, indeed, he was correct.

Like if you assume this was an alignment –

This would have lined up right on basically 12,000 years ago, 13,000 years ago, 10,000 BC, or plus 41,000 years, I guess, for the cycle.

And the guy, Gustavo, I've forgotten his name, damn it.

But the guy who was in charge of the Bolivian Department of Archaeology at the time, once he made that announcement-

Lost his job.

And I don't think he's ever been talked of since.

Yes, the official dates for Tiwanaku haven't changed.

However, these guys also figured out that if you spun it around and you looked from... It's also aligned to the sunsets on those solstices.

So if you go on the east wall and look west, it also perfectly aligns with the sunsets.

You also get the solstices in the center.

So...

equinoxes in the center solstices being the shortest and longest day of the year where the sun's furthest north and furthest south and then equinoxes in the middle so it's perfectly aligned with that but just off kilter a little bit because of that motion of the earth the change in the obliquity of the ecliptic so it's not an accident put it that way it's not just a coincidence that it's aligned this way it was set up that way to be a solar observatory

Yeah, it is.

I mean, even within this cycle of 10,000 BC, I mean, that's the Younger Dryas period.

Like this is, you know, this is... And it's a significant marker for South America because I can tell you the Younger Dryas had a tremendous impact on South America.
