When I was a young I contemplated the idea that our universe was somewhat like that of an single atom with its many parts. If you follow this out to our universe, you could surmise that there are many of the same, so in this case is more than obvious that we're not alone.
Thoughts about SETI and SETI@home
“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.â€
― Arthur C. Clarke
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.
