Hey, I'm Joel Stein. I want you to close your eyes and imagine a pocket watch.

It's moving from side to side. You're getting very sleepy.

Great. Now that I've hypnotized you against your will, you're going to start liking long-form journalism.

Like so much. You're going to listen to a podcast where the host interviews a writer about their long-form story every week.

I'm that host.

Listen to Story of the Week on the I Heart Radio app, Apple Podcasts, or wherever you get your podcasts.

On the podcast, Daniel and Jorge explain the universe. The guys talk about galaxies, planets, and different worlds.

And now you can check them out in another world, I Heartland.

For a limited time starting Thursday, November 17th at 7pm Eastern, you can watch Daniel and Jorge and I Heartland at State Farm Park tell crazy stories about the biggest collisions ever.

Awesome tales of planets smashing together and galaxies colliding.

Head to State Farm Park right in the middle of I Heartland for the biggest events happening in the metaverse.
