Hello, I'm Professor Brinkox and I'm a broadcasts. we've decided to take our show The Infinite Monkey Cage on tour across North America

to scrutinise the possible differences in thinking about particle physics, evolutionary biology

and very big dinosaurs.

This is what happened when we went to San Francisco.

So, this is the question we're asking. Could it really be possible that human beings are the most intelligent

creatures in the universe? Anyway so is it the duty of a sentient creature to

go in search of living things beyond their own planet or should we let them

get on with their own lives and just leave them alone? Is Stephen Hawking correct

in his suspicion that making extraterrestrials aware of our existence may lead to

our doom.

So, I hope you enjoyed my reading of doom there.

So we have a fantastic panel.

I think two of them have been on the show before and two are the first time.

So if you'd like to introduce our first guest.

Karen in Porco is a planetary scientist who's played a major part in creating some of the

most beautiful and enlightening images of our solar system.

She leads the imaging team of the Cacini spacecraft in orbit around Saturn,

and she's just been appointed as a distinguished scientist at both,

the California Academy of Sciences, and UC Berkeley. It's Carolyn Porco.
