For half a century, aliens have romped across the television and film screens and not surprisingly, this torrent of extraterrestrial visitors has led many among the public to believe that real aliens not only exist, but are visiting our planet. The UFO phenomenon has gone beyond being simply a popular myth; it is a cause celebre for many who feel that the government and the science establishment are conspiring to squelch the news of alien presence. Despite the drama and appeal of this argument, there's little evidence to support it. Yet a substantial number of scientists suspect that real aliens do exist. For several decades, a dedicated group of researchers has been looking for the proof - not in the skies above our homes, but among the vast, silent star fields of the galaxy.It's quite possible that by the year 2025, conclusive evidence for a civilisation light-years distant will be found. Reports of UFOs, which have taught us nothing, will be supplanted with a torrent of data, beamed from deep space on a radio wave or a laser beam. If that happens, what will we learn? What will the aliens be like, and what will happen to us? This informative and entertaining book investigates what we might discover somewhere out there, existing among the stars. It is likely that the true intellects of the cosmos are non-biological, and some of them will be privy to wisdom accumulated over ten billion years. What, if anything, they would tell us, and what their existence would portend for both Homo sapiens and the future of the universe, are the subjects of this book.
