From the campus of Hillsdale College in Hillsdale, Michigan, this is the Radio Free Hillsdale Hour, bringing the activity and education of the college to listeners across the country.

Here's your host, Scott Bertram.

Hello again, everybody, and welcome in to another

edition of the Radio Free Hillsdale Hour. On this episode, we'll talk with Timothy Dolch,

physics professor here at Hillsdale College, about the picture of the black hole. Christopher

Scalia with us to discuss his new book on Faith. Mark Meyer, assistant to the provost at Hillsdale,

gives us insight on the history of the book.

And Vince Bededetto, president and CEO of Bold Gold Media Group, will discuss radio and also why he's become involved with Hillsdale College.

First, join now by Dr. Timothy Dolch, assistant professor of physics here at Hillsdale College.

Dr. Dolch, thanks for joining us.

Thanks for having me. So a very exciting happening in the world of physics last week,

the very first picture of a black hole. We'll talk about the picture in a second, but for those

people out there who don't know, let's start with the very basic, which is, what's a black hole?

A black hole?

A black hole is a surviving remnant of an exploded star.

Very massive stars at the end of their lives run out of fuel and explode.

And the most massive ones in the process of that explosion will be very, very dense in the

middle.

And very, very dense matter makes for really, really strong gravity nearby.

So in the case of a black hole, the gravity is so strong that not even light can escape.

That's why we call them black holes because they don't emit any light.

And we're talking about visible light, radio waves, anything.
