Are aliens hiding their messages?
In an article to appear on May 10, the New Scientist carries a fascinating answer to the problem of why we never — yet — caught any signals from extraterrestrial civilizations. Here is a link to a preview of this article.
Two physicists have come up with an intriguing solution. They suggest a way in which aliens could send messages to each other across space that not only disguises their locations but also makes it impossible for a casual observer to even distinguish the messages from background noise. Messages sent by this method could be criss-crossing our Galaxy without us ever knowing.

Paul Shuch, director of the SETI League in New Jersey, points out that being able to disguise a sender’s location would be extremely useful for secure military communications here on Earth. “In a few decades, when it’s declassified, we may well find that such a technique is already in use.”
