Transmission: The Other Side of SETI


David F. Mayer




The thesis of this paper is that the best way to answer these questions is to look at SETI from the perspective of the civilization which is attempting to TRANSMIT to another. I t is concluded that the visible band presents the most viable medium of contact, since it offers both the greatest bandwidth and the most narrow focusing, permitting the most information to be transmitted to potential targets at the lowest cost.  The essential problem of defining the meaning of a message to an unknown civilization is solved by the concept of the self-describing message.  The problem of the selection of potential targets is discussed and criteria for optimal choice are given.  Finally, the key question of the prudence of such a transmission program is presented and discussed.
