I run SETI@home because I find it interesting as to what we are sesrching for. I think there very well could be life in space, but we will just have to wait to find out, you just never know!
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.
