Summary

By analyzing the pottery from an archaeological dig near Jerusalem, scientists have learned that the geomagnetic field around the earth fluctuated wildly during early human civilizations —and the news isn't good for a world that depends on electrical grids and high-tech devices. Jeff and Anthony discuss magnetic fields, scientific sleuths, and Santa Claus.

0:10.0	you can head to patreon.com slash we have concerns.
0:13.2	I don't know, so you might as well burn them. Burn all your comics. This is we have concerns.
0:31.1	I Jeff can I have the neat car boning concern citizens. This, this is an interesting story. This
0:37.9	was sent to us by Jean man 67 on the subreddit. Jean man. Jean man. I wonder if his name is just
0:45.5	Jean. And it's like, Hey, Jean man, this is a story about the geomagnetic field that wraps around
0:52.0	planet earth. I'm sure you're aware of it. Yep. It protects us from solar winds and high energy
0:58.7	particles from space. Yep. It's there to protect us, but you know, we don't really know much about
1:03.8	it. We don't know how it works. Why it works. What it's constant state is it fluctuates. And in fact,
1:10.6	this new article or this new study, this new evidence points to what could have been a massive
1:19.2	geomagnetic spike that took place in the first millennium BC. So just a huge, a huge fluctuation of
1:28.2	a massive magnetic energy, a massive spike in geomagnetic energy. And how they figured this out,
1:34.0	how they came to believe that this happened is absolutely fascinating to me. What they did
1:40.4	was they took a bunch of pottery from Judah, the ruins of Judah. And they analyzed it. And what they
1:48.0	analyzed was traces of iron in in clay. Okay. And they checked out what the positioning of the iron
1:57.1	in the clay was in the handles. Oh, that's dope. That's some Batman level shit. See, what happens is
2:04.8	when you heat up iron in a kiln, what happens is if it's above its curie temperature, which is
2:12.2	770 degrees Celsius, it becomes non-magnetic. And when fire, when clay is fired in a kiln, it's
2:20.2	well above the curie temperature. And so, wait, so then as it cools, it's like it would form
2:28.8	back into being magnetic and orient itself. So the north and south pole goes where the geomagnetic
2:36.0	energy is coming from. Right. So it becomes liquidy, right? Like the clay. Exactly. And then as it
