ET Probes: Looking Here as Well as There

: Probes, SETI, ET, Altruism, AsteroidsAbstract:
Almost all SETI searches to date have explicitly targeted stars in the hope of detecting artificial radio or optical transmissions.
It is argued that extra-terrestrials (ET) might regard sending physical probes to our own Solar System as a more efficient means
for sending large amounts of information to Earth. Probes are more efficient in terms of energy and time expenditures; may
solve for the vexing problem of Drakeís L factor term, namely, that the civilization wishing to send information may not coexist temporally with the intended recipient; and they alleviate ETís reasonable fear that the intended recipient might prove
hostile. It is argued that probes may be numerous and easier to find than interstellar beacons.
