For hundreds of years, people have speculated about life on other worlds, but (apart from some fantasies) we are still seeking that first contact. SETI radio transmissions, space probes and planetary missions now headed out to the stars all proclaim our arrival to the galaxy, but where are the others? How many stars are there in the universe? What kinds of stars can bring forth and maintain life around them? What kinds of planets can be host to life as we know it, and is life itself common among the countless worlds scattered throughout the vast cosmos that we can see, a vision that astronomers tell us is only a fraction of the potential expanse of our known universe?
Join facilitator Tim Bloch to engage in this fascinating conversation, presented from the vantage point of what science knows now. This inquiry will reflect serious academic viewpoints and will not be a forum about space invaders, conspiracy theories, magical components of ancient religions, flying pyramids or aliens living among us. If time and interest allow, we may look briefly at the development of life on earth, some of the past history of our planet and how that history has shaped our own evolution.
We will begin the conversation on Tuesday, February 16 and 23 from 5 – 6 p.m., via Zoom.
