for me Seti@Home will only be a matter of time before we pick up some kind of alien signal, the universe is so vast that it would be quite naive to think we are the only ones out here.
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.
