I don't know if extraterrestrial life exists as we know it. The important thing is that if we find it; what are we going to do about it?
But how could we know what to do, if we can bearly imagine the possibility?
That's why I run SETI@home; I would like to know what is humankind going to do whenever this happens, either in a few years or in a thousand years. I know I wont see it if it happens in more than a hundred years, but someone had to started it!
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.
