Aliens might have been sending mysterious signals to Earth but scientists misunderstood it, claims a professor at Harvard University. Strange messages received on Earth from satellites might actually be leakage from a huge light-powered spaceship deep in space, says Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. He claims that Fast radio bursts (FRB), which have perplexed scientists, could be evidence of advanced alien technology.
Fast radio bursts, whose source is yet to be identified are flashes of radio emissions lasting milliseconds. They were first discovered in 2007 when scientists stumbled across data that showed a burst in 2001. While only a few have occurred since that time, scientists noticed that FRB arrive in apparently organized patterns.
Loeb thinks that these patterned signals might be some mysterious leakage of alien communication signals from planet-sized transmitters. Originally misunderstood as random radio signals, near about two thousand such strange signals have been detected by massive radio telescope like the Parkes Observatory in Australia. Now scientists are debating whether these mysterious messages are sent by aliens to the humans on Earth, or if these are again just random signals from long lost satellites, the Independent reports.
After a number of investigations and researches, scientists reveal that these radio signals are sent from distant galaxies which are billions of light year away from Earth. Loeb thinks that the transmitters that produce the FRB are powering interstellar probes in distant galaxies. Attempting to ascertain the origin of the radio signals, Loeb and other fellow Harvard academic Manasvi Lingam have studied the signals extensively to determine if the messages could emanate from a radio transmitter, the Science Examiner reports.
In a paper exploring the possibilities of alien technology, and to be published in The Astrophysical Journal Letters, the scientists formulated the features of these radio signals in details. It would require a planet-sized solar-power generator to catapult messages across the galaxy. However, researchers remain far from confirming whether the source of these “messages” are actually from extraterrestrials.
