Does Alien Life Exist? (Featuring Xinnan Du)
Are there any life forms out there, in our galaxy, or beyond? If so, are any of them intelligent and capable of communicating with us? If so, what are they like? And why haven't we heard from them? All of this is encapsulated by the field of astrobiology, and to help us navigate this speculative terrain is postdoctoral researcher and NASA program manager in the department of physics and astronomy at UC Riverside. We will talk about the requirements for abiogenesis, for subsequent evolution, the Drake equation, the Fermi paradox, you name it! This is my absolute favorite thing to talk about, so I hope you'll have as much fun as I did.
