I'm Lindsay. And I'm Marshall. And welcome to Tumble, the show where we explore

Tumble's brought to you with support from Spotify for podcasters. If you're so

inspired by me and Lindsay that you want to make a podcast of your own, Spotify

in Austin, Texas with some fifth graders who really want to know about astrophysics.

Okay, I'm Jack and I'm 11. I'm Kate and I'm 11. Jack and Kate were super excited
