So first off, thank you to everyone for sticking through that multi-part epic saga of general relativity.

It was like for me, for me, I know it's not the longest podcast in the world, but for me that was like the

Iliad of podcast. It was just this

giant poem of, of this crazy battle of grappling with gravity and Einstein's struggle. It was,

it was great. And I could have gone on longer. There were like entire sections of my notes that

I got to. And I said, as I was reading it, as I was, I would get to

section of my notes and say, I'll just skip it. I'll just skip it because I know this is running

long. So I'd love your feedback because that was an experiment for me on longer multi-part episodes.

I know I've done two-parters before. That was the first time I've done a three-parter. It could have easily been a four-parter. I had way more material, so I'll just have to save that for a new episode.

It was an awesome journey for me.

I hope it was an awesome journey for you, too.

I would love your feedback.

If you'd like to see more of those multi-part episodes

or you like the single ones like today's, just let me know.

I'd love to hear what you thought of an episode series like that. But on today's topic,

because after a heavy meal, like, I don't know, all of general relativity, I need, I'm still

a little bit hungry, even though I have a giant greasy gut-busting meal, you know,

you have just, you want something sweet. You want just a little bit of

dessert to just top it off and to call it a night. And that dessert for us today, after the three-part

general relativity series, is a mystery, a high energy who'd done it. And the mystery begins on the night of October 15, 1991. It was a cool,

dry, dark in the desert, western Utah desert. And there, the University of Utah's fly's eye

cosmic ray detector saw a brief scintillating flash of light.
