scientific discipline fiction author Gregory Benford and his twin brother , the physicist James Benford , say that scientist are tackle the search for intelligent life as if aliens had 1960s - epoch technology . Here are their suggestion for update the search for ET .
According to MSNBC , which has a marvellous , lengthy article on the pal ’ research :
Assuming that extraterrestrial would strive to optimise monetary value , limit waste product and make their signaling applied science more effective , Benford and his twin , James a fellow physicist who specializes in high - power microwave oven technology suggest the signal would not be steadily blast out in all focusing . Extraterrestrials would be more likely to place narrow “ searchlight ” beams delivered in pulses .
“ This overture is more like Twitter and less like ‘ warfare and Peace , ’ ” say James Benford , founder and President of the United States of Microwave Sciences Inc. , in Lafayette , Calif. The Benford twins , along with James ’ son Dominic , a NASA scientist , detailed their determination in two study appearing in the June number of the journal Astrobiology .
The Benfords suggest a continuous sign blared at thousands of adept would only cost too much vim . They say aliens might use short volley say , anywhere from a second to an time of day long and manoeuver these signals in narrow-minded beams at one hotshot and then another in a cycle require up to yard of stars that repeats over day or age .
For civilizations that constantly learn the skies , the bursts would convey enough information to be recognized as undeniably artificial . As observing civilizations concentrated on this simple radio beacon , other beacon light could broadcast more complex data point at low office ( assuming the unknown were still quest after a frugal strategy ) .
The Benfords suggest depend at a all-inclusive cooking stove of radiocommunication signal in the 1- to 10 - gigacycle per second range , where the travel of light is comparatively unimpeded by interstellar matter . Currently SETI is focalize on just the 1 - to-2 gigahertz area , where components of pee such as hydrogen and hydroxyl ( a chemical compound of atomic number 1 and oxygen ) emit tuner signals .
“ The idea is really based mostly on how all the electronics of the 1960s , when SETI was first jump out , only operated in the range of a few gigahertz , ” Gregory Benford explicate . “ Now they engage in a range of up to 100 or 200 gigahertz , so it ’s a reason to revisit our laying claim . Looking to 10 gigahertz makes common sense , since it ’s cheaper by a factor of 10 to make a transmitter at 10 gigahertz than at 1 gigahertz . ”
They also steer out that we should be scanning the skies 1,000 light year away , in the center of our galaxy , where there ’s an unbelievable concentration of senior star that might have developed aliveness long ago . In plus , they consider whether we may already have picked up some alien communications via a radio source that seems to be pass around in a 77 minute oscillation . The radio signaling , called GCRT J17445 - 3009 , comes from an unknown informant – it could very well be natural . But if it is n’t , say the Benfords , it might actually be aimed at communicating with Earth . Or it might be “ one link in an interstellar communication connection . ”
