Camden Public Library invites the public to a presentation by Tim DellaPenna, where he will discuss the multiple factors involved when contemplating the existence of aliens. A Q&A session will follow the presentation. The event will take place Tuesday, Nov. 18, at 6:30 p.m., in the Picker Room at Camden Public Library. This event is free and open to everyone.

Tim DellaPenna will introduce and teach multiple concepts including the Fermi Paradox, UFOs, Drake’s Equation, the evolution of life on Earth, and the numerous conditions a planet must meet to support life. The presentation will also delve into the difficulty of estimating how many intelligent civilizations may exist beyond Earth, how they might be detected, and how we might communicate with them.
