I live in Tucson, Arizona. I retired after 28-years in the US Air Force as a medical technologist. I have 7 wonderful grandchildren to spoil, and am doing my best. I recently gave up motorcycling and am now keeping aquariums, building computers, and looking forward to the next new pastime.
Thoughts about SETI and SETI@home
I think its unlikely that Earth is the only inhabited planet. I hope we can discover ET during my lifetime. The largest benefit, to me, would have to be that we finally realize that we are Earthlings rather than Americans, Canadians, Ethiopians, etc., and we're all in this together.
I'm not sure sending a beacon would do any good. We have been sending radio and TV signals for over 50 years. If ET is listening, maybe there is a signal already heading back to us.
I run SETI@home because the project is worthwhile, and on the cutting edge. I wanted to participate in the largest computer sharing project to date, and would be thrilled to be part of the discovery of a lifetime.
