You know what time it is. It's time for Ask a Space Man. I'm your host, Paul Sutter. You've got questions, and I've got not all of the answers, but a large chunk of the answers. You know how the show works.

You go online to Twitter or Facebook. Use the hashtag Ask a Spaceman. Send me questions and I answer

them. Pretty easy exchange. If you don't like Twitter or Facebook, you can also go to

Ask aSpaceman.com or you can email Ask a Spaceman at gmail.com. And you can also follow me on Twitter and

Facebook. My name is Paul Matt Sutter. We have, you have, I have, we all have a very simple goal with

this show. Complete knowledge of time and space. It will take us a really long time. and that's it. It'll just take us a long time.

Anyway, on the road to complete knowledge of time and space is another very special edition. What I did

is my last episode, I talked about the work of William Fowler and stellar nucleosynthesis and

how elements are created, where we come from, all that great stuff.

And that was part of a live event I did in Lima, Ohio.

And now what I'm going to do for this episode is I allowed lots of time for questions.

And I actually gave two talks on the same day,

one to students and then one to the general public.

And I only talked for like a half hour.

And I left plenty of time for questions

because I love leaving time for questions.

And so what I'm taking now,

I'm taking those questions and I'm

packaging them up. So what you're about to hear are my live, unrehearsed, unscripted,

spontaneous answers to questions that people came up with in the audience. I had a really

great time answering those questions. You'll hear lots of little different topics. If you want to dig into any of these topics more, just let me know and I'll devote an entire episode to fleshing out those concepts. So without further ado,

Oh, front row right here. How old is a pulsar? How often is a pulsar?
