Albeit not being native from Algarve (southern Portugal), I am living in this province for more than 10 years. I'm a 32 yo male, currently engaged in marine environment projects.
Thoughts about SETI and SETI@home
1. I can not honestly say I do believe in ETL, but I believe it is worth the effort. Go for it!
2. Yes. And I would not know - that would be one of the most dificult collective decisions mankind would be faced with.
3. Why not?!!? It is easy to help!
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.
