Hello … Is Anyone Out There? 

Have you ever read a story about someone who says they have been abducted by aliens? Or perhaps they claim to have seen a UFO? Most people don’t take these tales seriously, but let’s face it: most of us have at some point found ourselves gazing up into the starry night sky, wondering if we are alone in the universe or not. But for some people, A …… They point out that there are more stars in the cosmos than grains of sand on all the beaches of the world.They are convinced that ET and his friends are indeed out there and if so, they are determined to establish contact!

In the 1960s, astronomers of the Search for ExtraterrestrialIntelligence (SETI) programme began their high-tech hunt for extraterrestrial life that continues to this day. The scientists listen to radio waves by sweeping the skies with huge radiotelescopes such as ‘Arecibo’ in Puerto Rico. They also comb the skies B ….. that alien civilisations might be beaming across space. The searches are based on the hypothesis that aliens may be intentionally sending communication signals out across the universe, or that signals from their worlds could be escaping into space — just as our own radio, television and military broadcast signals escape into cosmos. 

Unfortunately, the scientists may have to face the fact that the possibility of finding what they are looking for is very small. For a start, even if these ‘alien civilisations’ do exist, they might not be technologically advanced enough to communicate over long distances. The fact C ….. is pretty discouraging. If they don’t have radio, SETI won’t find them. Also, with a hundred billion stars in our galaxy alone, and a billion possible radiochannels to choose from, it might take a very long time for us to tune in to ET! So, why don’t we send our own messages instead? Well, simply because it’s just not that interesting for us. Even if the nearest civilisation was as close as 500 lightyears away, we would have to sit around for 1000 years waiting for a reply! All the same, in 1974, we did broadcast a radio message containing basic information about the human race. It was directed D ….. . If there is intelligent life there, we will hear from them around the year 52,000! 

So, how do you fancy joining in the search for intelligent alien life yourself? Well, the ‘SETI@home’ project allows you to do exactly that. After downloading a clever screensaver, your computer will analyse unknown or unusual signals from radio telescopes whenever you are not using it. Millions of people in over 200 countries E ….. .

So where do we go from here? Well, despite the fact that we have not yet found a shred of convincing evidence that alien life exists, one thing is for sure – F …..! But perhaps we’re forgetting one important thing. We want to talk to aliens allright, but do the aliens want to talk to us? Only time, perhaps thousands of years, will tell!
