Hello Universe!
Are there intelligent beings in other parts of the universe? Twenty years ago, radio telescopes gave us the means to receive, and make, galactic telephone calls. So far, no one has called us - and no one answers when we call.
But most scientists are convinced .they are there. From present knowledge of ' life, the universe, and everything ' they estimate that the galaxy is swarming with life. So where is everybody? Some of them, at least, should have paid us a visit, but evidence for flying saucers is disappointingly nebulous. Are they out there listening to the blare of TV signals radiating from our noisy planet? Or is it possible that, after all, we are alone-that the galaxy's first inter-stellar spaceships will be ours?
