What else might Astropulse find?
In addition to ET, Astropulse might detect other sources, such as rapidly rotating pulsars, exploding primordial black holes, or as-yet unknown astrophysical phenomena. You can imagine that SETI@home is a search for a gold needle (ET) in a haystack. During the search for a gold needle, Astropulse might occasionally find a silver needle (a pulsar or black hole.) These silver needles have their own scientific value, even if they don’t represent extraterrestrial communications.
