Hey everyone, Fraser here. This is a special bonus episode that I did with Dr. Paul Sutter

when we were on our Astritur's trip in Costa Rica. Paul and I got a chance to sit down and talk

about the nature of dust and and what impact it played on the the bicep to claim of discovering

give you an idea that this is sort of the kind of content, the kinds of things that we do during

Skylius, John Michael Goede and it goes from June 26 to the 30th. And we're going to be staying in

this really fancy hotel. We're going to be looking at the stars every night and we're going to be

going on all kinds of interesting trips around the area. So if you're interested, go to astritururs.co

there can only be one best friend. You can't have many. You have better friend that I did.

Okay, never mind, never mind. But the purpose of this of course is whenever Paul and I are on one

of the astritururs, this one in Costa Rica I like to corner him and grill him on a bunch of

astronomy questions. And this is no exception. And so the topic that I wanted to talk about today,
