Hey Marshall, today we have a big first on tumble.

What kind of first is it like we're gonna walk on the moon?

Not quite. It's our first episode with a question we got by email from one of our listeners.

Well, I mean I guess somebody already walked on the moon once, so this is probably a better first.

Exactly. But really we are so excited to start answering questions from listeners all over the world.

So here's what you do if you want to ask a question on tumble.

Ask a friend or a friendly adult to help you record a question for us on a smartphone or computer.

Ask us your question, but we also want you to answer our questions.

What do you think the answer is and how do you think scientists would find out the answer?

We can't wait to hear what you have to say.

Hi, I'm Lindsay.

And I'm Marshall. Welcome to tumble, the show where we explore stories with science discovery.

Today's show is about everyone's favorite space object of doom.

And we're not talking about the death star. We're talking about black holes.

Black holes! How do scientists find out about them without getting sucked inside and never escaping?

And what do they want to know? We're about to find out.
