AskScience AMA Series: I'm Paul Sutter, astrophysicist, amateur cheese enthusiast, and science advisor for the upcoming film UFO. Ask Me Anything!

Hey reddit!

I'm Paul Sutter, an astrophysicist and science advisor for the film UFO, starring Gillian Anderson, David Strathairn, Alex Sharp, and Ella Purnell. I am not nearly as beautiful as any of those people, which is why I'm here typing to you about science.

The film is about a college kid who is convinced he's recorded an alien signal. I helped writer/director Ryan Eslinger, plus the cast and crew, make sure the science made sense. And considering such topics as the Drake Equation, the fine-structure constant, 21cm radiation, and linear algebra are all (uncredited) costars in the movie, it was a real blast.

I also briefly appear in one scene. I had lines but they didn't make the final cut, which I'm not bitter about at all.   

Besides my research at The Ohio State University, I'm also the chief scientist at COSI Science Center here in dazzlingly midwestern Columbus, Ohio. I host the "Ask a Spaceman!" podcast and YouTube series, and I'm the author of the forthcoming Your Place in the Universe (which is like Cosmos but sarcastic and not a TV show). I do a bunch of other livestreams, science+art productions, and TV appearances, too. I also consult for movies, I guess.

I'll be on from 2-4pm ET (19-21 UT), so AMA about the science of UFO, the science of the universe, and/or relationship advice. As I tell my students: my door is always open, except when it's closed.

What has prevented you from taking that step up from amateur cheese enthusiast to professional cheese enthusiast?  Is it giving up the glitz and glamor of the astrophysics world or do you secretly think you might not have what it takes to compete in the high stakes world of cheese enthusiasm?
