It's actually very close to being – if you go to the north pole and look straight up, it's very close to being directly above you.

In any human timescale, it does. Over thousands and tens of thousands of years, it changes. But right now, for the next couple thousand years – so don't worry. You'll still be accurate. That is within a half a degree or so.

Well, I say it like this. The universe could end in a heat death and a big rip or whatever, but that's not for a trillion years, so everybody keep paying your taxes. So you could use it for navigation. So you could know your latitude, but measuring longitude was very difficult because you couldn't actually – to know longitude, you need to measure time relative to where Greenwich Mean Time is.

That's how Greenwich became – so important and that's why London had its huge economy. Again, these things are always related to capitalism and even how we measure latitude and longitude comes from the fact that London and Thames River, 90 percent of the world's commerce flowed through there at one point or another. It's incredible. So anyway, latitude and longitude is very important.

People started to know that, yeah, these events would occur and including this event with Columbus and he brought along with him on his voyage an astronomer. And this astronomer knew that in two days' time from when these natives had captured some of Columbus's crew that there was going to be a total solar eclipse and it was going to go through Jamaica.

And he said – he told Columbus and Columbus said to the inhabitants, if you don't give our people back, our god is going to obscure and kill your god, the sun god. They're like, F you, whatever. And then it happened and they totally believed that they were in control of these celestial events. We better give the people back and Columbus got the hell out of there. So it's an amazing story.
