Thoughts about SETI and SETI@home
I tend to subscribe to the Rare Earth theory, thinking that there are just too many filters in the way to technological intelligence... but we have to look.
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.
