Rocky little ball, isn't it?

Bro, that's crazy.

Yeah, some of those oceans are deep.

Yeah, you think?

Jeez.

That's cool.

That almost looks exaggerated to me, that a little bit.

Yeah, so it must be a little exaggerated because I think that's clearly rougher than a...

orange than the rough that's clearly thicker than the roughness of an orange skin but yes yeah that's an exact it gives us an example but it so yeah so we're a little little bulgy around the middle a little flatter on top so when you get down to latitude and longitude at the equator right so the at the equator what if you draw that cube one degree

of latitude and one degree of longitude, it's not a perfect cube, okay?

So it's a little bit further east to west than it is north to south.

So if you cut that down into like 60 seconds of latitude and longitude, it's a smaller little square, but same proportions, you have the same ratio.

And if you actually take the Great Pyramid, so the thing to understand about the Great Pyramid

is that it sits on a socle.

I don't know if I've talked about this before, but so we know because we have casing stones, we have that 51 degrees, 51 minutes angle of these casing stones.

So we were able to really act and we have a few of those still around the base from where they fell off.

So from that, we can determine the height and we also have this perimeter length using the casing stones.

pretty very accurately this survey and now those casing stones it doesn't sit direct on the bedrock the pyramid actually sits on top of a 55 centimeter socle so it's this it's this little platform that sticks it sticks out about this much and it's 55 centimeters high and it's like sticks out so you have the casing stones you have this little socle that it sits on so you have these two methods of measuring the pyramid you can measure the perimeter length around the casing stones or you can measure the perimeter length around the socle socle's slightly larger

And the funny thing is, is if you get down to one quarter of one second of latitude and longitude at the equator...

the longitude is exactly within an inch or two the perimeter length of the socle, and the latitude, the north-south, is the perimeter length of the pyramid.
