ALIENS may be sending each other secret messages buried in background noise, it was claimed yesterday.
Two scientists have come up with a possible solution to the long standing puzzle of why, if alien civilisations are out there, no one has ever picked up signals from them.
The Fermi paradox, first posed by the physicist Enrico Fermi, is still one of the strongest arguments against the existence of intelligent aliens.
But Walter Simmons and Sandip Pakvasa, from the University of Hawaii at Manoa, have worked out how the aliens could be hiding.
First the signaller splits the message into two parts, so that its photons are sent in opposite directions to mirrors far from the home planet.
The mirrors redirect the signals to the intended receiver, who recombines the photons to reconstruct the message.
Neither the intended receiver nor any eavesdropper would be able to locate the home planet of the sender. Furthermore, it would be impossible to detect the message at all without extremely sophisticated technology, New Scientist magazine reported.
To recombine the beams and recreate the message you would need to detect the arrival time of the photons extremely accurately to identify pairs of photons split by the sender.
Mr Simmons said, "Such photons are distinguishable from the background of stellar photons because they arrive very close together in time. But any eavesdropper, like us, might not realise this and see only the background."
Jonathan Rosner, a physicist at the Enrico Fermi Institute in Chicago, said, "The proposal is ingenious." But he said it was hard to tell if the method could work in practice.

You are joking, right?

wow very intresting, Now it makes me want to beam a message saying "we know your out thier"
