63: Ugly Bags of Mostly Silicon

The Definition of Life.   "To seek out new life...." Such is the mission statement of Federation starships, to discover and learn as much as possible about life in the universe. But given the diversity of life forms in the Star Trek universe, here on Earth in the real world, and possibly elsewhere in our own galaxy, how do you recognize a new lifeform as life when you first encounter it, especially exotic or non-carbon-based lifeforms?   In this episode of Meta Treks, hosts Zachary Fruhling and Mike Morrison discuss the philosophical and scientific challenges of determining a precise definition of "life," both inside and outside of the Star Trek universe. Is it possible to give a definition of "life" that is broad enough to include radically different forms such as silicon-based life (e.g., the Horta in Star Trek: The Original Series) and non-corporeal life (e.g., the wormhole aliens in Deep Space Nine), but also narrow enough to exclude nonliving entities that merely mimic signs of life?   Chapters  Welcome to Episode 63 (00:01:07)  Dr. Crusher's Definition of Life (00:02:01)  Defining "Definition" (00:02:40)  Silicon-Based Lifeforms (00:47:30)  Non-Corporeal Lifeforms (01:12:09)  Other Fringe Lifeforms (01:19:30)  Closing (01:30:05)   Hosts Zachary Fruhling and Mike Morrison   Production Mike Morrison (Editor) Zachary Fruhling (Producer) Matthew Rushing (Executive Producer) Ken Tripp (Executive Producer) C Bryan Jones (Executive Producer) Patrick Devlin (Associate Producer) Kay Shaw (Associate Producer) Kit Loffstadt (Associate Producer) Richard Marquez (Production Manager) Brandon-Shea Mutala (Patreon Manager)   Send us your feedback! Twitter: @trekfm  Facebook: http://facebook.com/trekfm  Voicemail: http://www.speakpipe.com/trekfm  Contact Form: http://www.trek.fm/contact  Visit the Trek.fm website at http://www.trek.fm/  Subscribe in iTunes: http://itunes.com/trekfm   Support the Network! Become a Trek.fm Patron on Patreon and help us keep Star Trek talk coming every week.
