Do you ever feel like you're being watched... by aliens? The "Zoo Hypothesis" as it is known in science circles speculates that some form of advanced, alien beings are watching us but deliberately not contacting us so as to not interfere with our evolution. Sort of like "Star Trek's" Prime Directive. But what if we reached out to them first and let them know we'd like to meet? Is that even a good idea or could it lead to unintentionally attracting the attention of a malevolent species who might want to attack us? Teddy and Richard are joined by world-renowned astrobiologist and President of METI (Messaging Extra-Terrestrial Life) Douglas Vakoch to seriously ponder, "what If we lived in a galactic zoo?"
