Been running SETI on and off since 1999 (party like it's..)
Thoughts about SETI and SETI@home
Yes I do think they exist.
Humans should transmit a powerful beacon from most countries to ensure it flows out to all points of space.
I run SETI because I feel I am contributing to an important project.
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.
