Of course I believe that SETI@home is a very good program. Through this program we are working on a important project for help finding extraterrestrial life. Think it takes a lot of computation power to check for messages intelligible in the waves reaching us from space. In this vast universe it would be sighted and presumptuous beyond the realms of logic believe we are alone. And if you're one of those who believes that there can be no extraterrestrial life, just a little sentence: "Think that you are alone in universe is a selfish attitude".
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.
