I believe science has the answers to everything (even though we don't know them yet, and maybe never will). Seti@home is the way in which I can contribute to modern science and maybe help us find out a little more.
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.
