Look around you. Breathe in some air. Everything you can see and feel was formed in a star. Today we’ll examine that long journey that matter has gone through, forged and re-forged in the hearts of stars. In fact, the device you’re using to listen to this podcast has some elements formed in a supernova explosion.

Questions Show – Black Hole Surfaces, Magnetic Field Strengths, and the Speed of Gravitons
As you know, we wanted to answer listener questions regularly, but we found it was taking away from the regular weekly episodes of Astronomy Cast. So we’ve decided to just split it up and run the question shows separately from the regular Astronomy Cast episodes. If this works out, you might be able to enjoy twice the number of Astronomy Cast episodes. So if you’ve got a question on a topic we cover in a recent show, or you just have a general astronomy question, send it in to info@astronomycast.com. Either by email, or record your question and email in the audio file.
Ep. 106: The Search for the Theory of Everything
At the earliest moments of the Universe, there were no separate forces, energy or matter. It was all just the same stuff. And then the different forces froze out, differentiating into electromagnetism, the strong force and the weak force. Today we’ll look at the problem that has puzzled physicists for generations: is there a single equation that explains all the forces we see in the Universe. Is there a theory of everything?
Student Questions Show: Leelanau School
This is our forth installment in our series of student questions shows and these questions come to us from Leelanau High School.
Thanks to GLAST, Astronomy Cast is now able to provide equipment to send to high school teachers who want to Pamela and Fraser to do a special questions show just for their class. We will be making this shows available on the feed on days other than Monday (that’s still reserved for your regularly scheduled Astronomy Cast).
To find out how your class can participate, check out our new Education page for details or drop us an email to info@astronomycast.com
