EARTH is becoming "invisible" to aliens, the world's leading ET hunter claimed yesterday. Dr Frank Drake said transmission of signals into space was being cut by the digital revolution.
As a result, any little green men on other planets would not be able to detect them.
Dr Drake said Earth was surrounded by a 50 light year-wide "shell" of radiation from analogue TV, radio and radar transmissions. The signals had spread far enough to reach nearby star systems but are vanishing.
He explained that while old-style TV transmissions could generate one million watts, digital transmissions are much weaker.
And satellites aim their transmissions to Earth - with almost none being allowed to escape into space.
Dr Drake said: "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 believed that intelligent life DOES exist beyond Earth.
He reckoned alien civilisations were likely to be far more advanced than ours and that their analogue TV age probably went long ago. That in turn means that the world's search for their signals is that much harder.
Dr Drake - who founded US-based organisation SETI (Search for Extra-terrestrial Intelligence) 50 years ago - told a meeting at The Royal Society in London: "We're going to have to search many more stars and many more frequencies."
One thing and one thing only is preventing the space aliens from invading immediately and becoming our new overlords: global warming.
It’s noncanon. I remember them using it in the novels to explain how “Zefram Cochrane of Alpha Centauri” could be right next door, but by 1996 they decided Cochrane just settled there after developing warp drive in Montana.
Which part of that did you not understand?
We could be in the way of the new intergalactic freeway.
Ruh...oh.
Which part of that did you not understand? I forget the exact circumstances, but either they got into a world war, and buried their communication links so that the “other side” wouldn’t be able to intercept any transmissions, or they became afraid that hostile extra-centauri intelligences might overhear them, and so buried their civilization so they wouldn’t be attacked.
Yes, YES! They taste like beer!
Don't Panic.
What should they use?
When they see our broadcasts of American Idol, Big Brother, Dancing with the Stars, and Survivor, they will realize we are dumb, edible, and slow. Let's hope they are not hungry, spacefaring, and determined.

Oh well, since you explained it THAT way....
My understanding is that there are certain radio wavelengths at which space is not "noisy", so to speak, and these are the ones that SETI listens to.
Don’t Worry Bout it...Al Gore will always remain in constant communication with the aliens...
What SHOULD they use? The one thing which propogates instantaneously to within our ability to measure it is gravity and the closest thing to a decent explanation of what gravity is, is Ralph Sansbury’s description of gravity and sub-electron particles. The computed necessary speed of a sub-electron particle would get you to one of the near galaxies in a couple of seconds. Anything which anybody with the brains and talent to communicate across cosmic distances would actually use would likely have to involve those kinds of particles.
“Dr Frank Drake said transmission of signals into space was being cut by the digital revolution. “
What an ignorant idiot the “Dr.” is. Digital transmissions are analogue signals. Cell phones, 802.11 wireless, satellite TV, etc, are all analogue transmissions. We have more transmissions than ever before.
The guy is a UFO moron.
Tim to cross them out of our phone book....they never call.
