And even more impressive is when you take the perimeter length of the Great Pyramid and you multiply that by 43,200, you get the equatorial circumference of the earth.

Within about 300 feet, which is super interesting because it's flexible.

It changes.

So as we've always known, there's been multiple surveys since the 1800s of the Great Pyramid.

And once its base was cleared off and we got its perimeter length.

And then we've also had surveys looking at, you know, how big is the Earth?

Aristotle is in like five, 600 AD in Greece.

He was the first one to give it a go by measuring sort of the angle of the shadow in two different places over a few years.

And he got the circumference of the earth to win about 500 miles.

That was as close as we got until the 1800s.

And then the advent of modern satellite surveys in the 1970s and 1980s.

And the funny thing is, is that the more advanced we got,

as we step closer and closer and right up to the modern satellite surveys, the closer the number came to what the Great Pyramid represents at this ratio of 43,200, right up to the point where it's like the most modern, I think,

The surveys done in the 80s are still the ones we use today looking at the actual circumference of the Earth is within about 300 feet of the measure of the Great Pyramid, which makes, I mean, that's within the margin of error.

It's within the variability of the margin of the Earth, of the circumference of the Earth, because you have like the moon and the sun on one side.

You measure it every day, it's going to change about 200 or 300 feet.

just because gravitational forces are pushing on the Earth.

So that also means that what's interesting is if in two seconds of time, if you were standing on the equator, then the Earth rotates precisely the length of the perimeter of the Great Pyramid.

So in two seconds, it goes... Basically, the Earth turns the same length as the perimeter length of the Great Pyramid.

What's even crazier... And so you have this measure expressed in...
