1. Do you think extraterrestrial life exists? If so, when and how will humans discover it? What are the possible benefits and dangers of such a discovery?
A: yes. i believe we will discover it through identifying ambient signals / informations in the atmosphere.
2. Should humans transmit a beacon for others to find? If so, what information should we send?
A: i believe it is naive to believe that all possible forms of advanced life in the universe will be benevolent. as such i think it would be foolish to advertise our existance before we (earth) have solved the problems facing us today.
3. Why do you run SETI@home? What are your views about the project? Any suggestions?
A: i like the team effort it represents, i was running distributed.net client but seti is so much more interesting :)
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
