SETI is linking the universe with us, despite extraterrestrial intelligence seems very far away from us.
The existence of the extraterrestrial intelligence is not important. The main point is we converge the global processor resources to do a research. It is adequate for our pride in this 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.
