many people don't realize that in addition to searching for radio waves. We humans are sending them out into space as well. This is because all of the radio and television signals that come into our homes also travel into space. We have been constantly and unintentionally leaking radio waves into space for over sixty years now. One day these signals may be detected by an alien civilization. In fact, it is possible that aliens are already listening to I Love Lucy,
The Simpsons, and American I dol !
