Hello, StarTalkians.

Every now and then, we reach into our archives to select some of our favorite shows of the past.

Right now, I offer you my conversation with Jan Eleven.

She's a cosmologist, as well as a friend and colleague,

and she will update us on all the latest thinking regarding black holes,

as well as whether the entire universe is a hologram.

Check it out.

This is StarTalk. I'm your host, Neil deGrasse Tyson, your personal astrophysicist,

and today's episode is Cosmic Queries, the Out There Edition. We're talking about not just astrophysics,

but the extremes of astrophysics in space, time, and dimensions.

While I have some expertise in that topic, I don't have all the expertise necessary to pull this off.

So we called in my friend and colleague, Janelle Levin, Jana.

Hello.

Okay.

Thank you for coming.

I love being here.

Not your first rodeo?

Yeah, not my first radio, but I haven't been in your office in a long time. Okay, well, it's fun to see it. It's gotten messier, just for you know. In kind of a good way. Almost like, I don't know, curatorial way. The curatorial way. And helping me bring some levity to this topic is the one and only Harrison Greenmount. Harrison. How you doing? Welcome. I do think we need to get Marie Kondo up in here.

Do you have to see which things topic is the one and only Harrison Greenmount, Harrison. How you doing? Welcome.

I do think we need to get Marie Kondo up in here.

Do you have to see which things spark joy?

It all sparks joy.
