"Radio telescopes designed to study the primordial universe could also
eavesdrop on extraterrestrial civilisations similar to our own. 'By a
happy accident,' says abraham Loeb of Harvard University, 'the
telescopes will be sensitive to just the kind of radio emission that
our civilisation is leaking into space.'
"The next generation of radio telescopes are designed to pick up radio
waves emitted by neutral hydrogen molecules in the early universe.
These signals originally had a wavelength of 21 centimetres, but the
universe has expanded since they were emitted, stretching the waves in
the process. Today, these signals have a wavelength of several metres,
corresponding to a frequency of tens or hundreds of megahertz. 'This
overlaps with our civilisation's radio emissions, which are in the
range 50 to 400 megahertz,' says Loeb."

Let's just hope their copy protection is crackable, and that they do not
come after you if you do!

I'm sure the dolphins, T-Rex's, spiders, little green bogeymen and
genetically modified wheat living on alpha-Cepheus IV will be very
interested in our military radar, reruns of the "Adams Family" in
monochrome, late night pornography and WW II war correspondents,
but for some strange reason we've reverted to cable and low power
directional antennae for our satellite communications.
Remind me not to take any interest in Harvard, ****wits named "Abe"
and to cancel my New Scientist free news letter. My subscription
to that august magazine expired long ago, about the time when I forecast
the iPod as a library book with access to all literature... 1983, I think,
when it was scoffed. Of course it was not called an iPod then... oh well,
I'll continue to visit the local library for my two tons of fiction each
year,
sooner or later the tree huggers will save me a walk and I'll still have
access to Harry Potter in the children's section.
At least J.K. Rowling writes honest magic to entertain without pretence
of it being "science".

The whole money-making racket is a joke. Real science is about
discovering Nature, not this "I'm smarter than you, I've got a theory"
one-upmanship bull.
