Ask a Spaceman!

What would happen if you fell into a black hole? How big is the universe? Just what the heck is a quasar, anyway? You've got questions, and astrophysicist Paul Sutter has the answers! Submit questions via Twitter using #AskASpaceman or post to Every week you will come closer to COMPLETE KNOWLEDGE OF TIME AND SPACE!


AaS! 004: Are there aliens...out there?

Are there know, out there? What are the chances of life appearing somewhere, anywhere, in the universe? Will we get to say "hi" and have a chat? Is there any life in our own solar system (uh, besides on earth)? I discuss these questions and more in today's Ask a Spaceman! 


Keep those questions about space, science, astronomy, astrophysics, and cosmology coming to #AskASpaceman, Twitter@PaulMattSutter,, and for COMPLETE KNOWLEDGE OF TIME AND SPACE! Music by Jason Grady and Nick Bain.
