Where is everybody? That was the question physicist Enrico Fermi asked when he wondered why we hadn’t yet met ET. What will happen if we do? Will humans lose the will to explore? These and other questions were taken up by Mat Kaplan’s panel at the recent Space Tech Summit, where he was joined by Bill Diamond and Seth Shostak of the SETI Institute, and Doug Vakoch of METI (Messaging Extraterrestrial Intelligence) International. Bill Nye reports on his successful trip to Washington DC, while Bruce Betts and Mat look up at the night sky and share a Random Space Fact.
