Looking for Lurkers: A New Way to Do SETI

  > If we find nothing there, this gives us a profound result: no one has come to look at the life of Earth Not quite. A probe can self destruct (like we did with Galileo and Cassini) or never even enter solar orbit. If I send a dozen probes in a single package and they disperse slowly from each other along the axis of travel, they'll pass Earth at long intervals. Using the available energy to send a message instead of slowing down and entering orbit would allow for a much stronger signal, with a lot more information packed in it.
