Even if these ‘alien civilisations’ do exist, they might not be technologically advanced enough to communicate over long distances.

Also, with a hundred billion stars in our galaxy alone, and a billion possible radio channels 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?

Even if the nearest civilisation was as close as 500 light-years 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.

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 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.

So far, however, ET is not ‘phoning home’!

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—the search will go on!

But perhaps we’re forgetting one important thing.

Only time, perhaps thousands of years, will tell!
