Chances of earth being detected by alien life forms are disappearing because of the digital revolution, a leading space scientist has claimed.

Dr Frank Drake said the phasing out of analogue transmissions from television, radio and radar was making our planet electronically invisible from outer space.

While old style signals used to spread out millions of miles into outer space, even reaching some distant stars, digital transmissions are much weaker and therefore are less easy to detect by extra-terrestrial life forms.

Scientists on earth are constantly monitoring the heavens for any sign of transmissions from other planets and it is assumed other life forms out there will be doing the same.

But Dr Drake, who founded the US based organisation Search for Extra-terrestrial Intelligence (SETI), 50-years ago, said the phasing out of analogue transmissions was making this virtually impossible.

He said the earth used to be surrounded by a 50 light year wide shell of radiation, with old-style television transmissions generating around one million watts.

But he said with satellites aiming much of their transmissions towards earth now virtually no radiation was escaping into outer space.

He explained: "Now the actual amount of radiation escaping is about two watts, not much more than you get from a cell phone. If this continues into the future, very soon our world will become undetectable."

Dr Drake said he remained convinced that intelligent life does exist somewhere in the universe but suggested it was likely to be much more advanced than here on earth.

He told a meeting at the Royal Society in London: "We're going to have to search many more stars and many more frequencies."

You haven't read the article I guess it is not about the discussion aliens are here yes or no. It is about our planet is becoming invisible from outer space.

Dr Frank Drake said the phasing out of analogue transmissions from television, radio and radar was making our planet electronically invisible from outer space.

While old style signals used to spread out millions of miles into outer space, even reaching some distant stars, digital transmissions are much weaker and therefore are less easy to detect by extra-terrestrial life forms.


So that could mean when ET is transmitting the same signals into space, therefore we cannot detect them with our instruments so for that matter ET home will be invisible to.

So the change they use similar transmitting devices is bigger then before

only thing is we would have to assume they are transmitting analog signals as opposed to

another form of communication
