Easier concepts and ideas are at the beginning while the more elaborate ones appear at the end of the message. Any true communication is not complete without an answer. Therefore, the last page of the message invites anyone who reads it to reply, sending information about themselves. The message has been built to minimize the loss of information due to noise introduced into the signal during its interstellar flight. To minimize the risk of confusion, a set of characters was created which are fairly different from each other.
Redundant information is included to allow cross-checking of the message.
The addition of a frame around each page of the message, and the inclusion of page and section numbers will also help the translation process. So far, the sky has remained silent. In order to maximize the probability of detection, the direction of the transmission has been carefully chosen to include stars similar to our Sun, and to limit the degradation of the signal as it travels through the vast reaches of interstellar space. Fortunately, there is a region between the spiral arms of our galaxy where the signal can be transmitted over long distances without too much degradation. Four stars, clones of our Sun, have been selected from the list made by the SETI institute.
