Is ET using Twitter? Scientists claim aliens are likely to be sending short messages to us from space

You are here: Home » Is ET using Twitter? Scientists claim aliens are likely to be sending short messages to us from space


Sometimes it seems as if the expansion of the social networking phenomenon knows no bounds.

And now scientists say even aliens might not be immune to Twitter.

They could have been using cosmic ‘tweets’ to contact us for decades, researchers claim – but we have been missing them.

The reason?While any ‘lost in space’ messages wouldn’t exactly be restricted to 140 characters, as on the website, a study suggests ET is more likely to send out short, directed messages than continuous signals beamed in all directions.

Because alien civilisations are likely to strive to limit waste and make their signalling technology efficient.

‘This approach is more like Twitter and less like War and Peace,’ said Dr James Benford, a physicist and president of Microwave Sciences.

His twin brother Gregory, an astrophysicist at the University of California, added: ‘Whatever the life form, evolution selects for economy of resources. ’Transmitting signals across light years would require considerable resources.’
The brothers looked at the search for another life form in the galaxy from the alien’s point of view.They concluded that scientists involved in America’s Search for Extra-Terrestrial Intelligence, or SETI, may have been taking the wrong approach for five decades.Writing in the journal Astrobiology, the Benfords said alien signals would not be blasted out in all directions but narrowly directed in the one to ten gigahertz broadband signal range.SETI’s search is like a lighthouse sweeping the galactic plane, say the brothers, but that could leave many days when brief Twitter-like bursts of ‘here we are’ flashes from alien civilisations go undetected.The Benfords also said SETI scientists had been looking in the wrong place.Their strategy involves listening out for unusual bleeps from targeted nearby stars.But they should be aiming at the centre of the galaxy instead, said the Benfords.‘The stars there are a billion years older than our sun, which suggests a greater possibility of contact with an advanced civilisation than pointing SETI receivers outward to the newer and less crowded edge of our galaxy,’ said Gregory Benford.‘The SETI effort is worth continuing, but our common-sense approach seems more likely to a answer those questions,’ he added.

    The analogy with twitter is terrible, really. The idea here is decent, however, there’s an element of game theory missing! If the intent of an advanced civilisation is to broadcast a message to be received by another then they must transmit that signal in a way that can be detected and deciphered by the other. If the other is of a more ‘primitive’ level of technology then they, the sender, must broadcast at that level. So, not knowing the technological level of potential recipients you are left with the conundrum of what format and which medium to send your message in. Putting aside the probability of another civilisation detecting any messages you send, if the aim is to send messages to unknown civilisations in the galaxy then, given the level of ignorance you have about them, you must broadcast loudly and in as many ways as you can. Limiting yourselves to short bursts of a tiny fraction of the EM spectrum is putting all your eggs in one basket.

    Seti is a smokescreen the aliens are already here, just checkout Bob Dean on you tube a former high ranking US Naval Officer. There you can also check out the message sent in a crop circle and decoded by Swiss physicist Naseem Haramein.
