We now have the technology to go snooping for extraterrestrials in our own backyard. No, not as close as little green men cutting up crop circles; instead, we should be able to detect an alien device positioned somewhere between the sun to 30 times farther out than Pluto.

What would aliens place 100 billion miles from the sun? Michael Gillon of the Observatory of Geneva, Switzerland wrote in a recent paper that extraterrestrials who are surveying our solar system with one or more artificially intelligent probes would need to set up a very powerful transmitter to the send data back to their home planet.

Green-minded (not necessarily green-skinned) aliens could save a lot of power and sidestep complex engineering by simply using the sun’s gravitational field as a powerful amplifier for sending and receiving messages from the home star. This phenomenon, called gravitational lensing, amplifies electromagnetic radiation just as a magnifying glass brightens the light from a source (as depicted in the artist’s impression above).

The home civilization would need a similar receiver set up at star’s so-called solar focal point. The transmitter/receiver pair would have their signals turbo boost by a factor of 500 billion billion times by gravitational lensing.

In fact, space scientist Claudio Maccone of the International Academy of Astronautics has argued that by solely using the gravitational focusing potential of the sun that we would be able to communicate with a probe sent to any of the nearest stars. So much for an abandoned alien “phoning home” with a transmitter fashioned from an umbrella and household batteries in the 1982 film, “E.T. The Extra-Terrestrial.”

Anybody with a little intelligence knows that Seti and NASA are just publicity stunts for the public.

They have been here before us
