“I don’t like alien films where you don’t get to see the aliens.”
– Peter Borg

“Is E.T. out there? Well, I work at the SETI Institute. That’s almost my name. SETI: Search for Extraterrestrial Intelligence. In other words, I look for aliens, and when I tell people that at a cocktail party, they usually look at me with a mildly incredulous look on their face. I try to keep my own face somewhat dispassionate.”
– Seth Shostak
