Aliens try to contact us by cosmic Twitter: Report

Aliens are more likely to be sending the humans short and direct messages than uninterrupted signals sent in all directions, The Telegraph quoted experts as saying.
"This approach is more like Twitter and less like War and Peace,'' said Dr James Benford, a Californian physicist said.
Along with his astrophysicist twin brother Gregory, Benford looked at the Search for Extraterrestrial Intelligence (SETI) from the point of view of the aliens.
Till now scientists have paid attention to the unusual beeps from targeted stars. But the doctor duo now claims that this approach can be wrong.
Rather, they propose that alien signals should be pulsated and specfically directed in the one to 10 gigahertz broadband signal range. The scientists should aim at the centre of the Milky Way, rather than focusing with their antennae at nearby stars.
The Benfords claim that an aliens would like to reduce costs, restrict waste and make their signalling technology effective.
''The stars there are a billion years older than our Sun, which suggests a greater possibility of contact with an advanced civilisation than does pointing Seti receivers outward to the newer and less crowded edge of our galaxy,'' said Gregory Benford told The Telegraph.
