Harvard Astrophysicists: ‘Extragalactic Fast Radio Bursts Could Be From Alien Spacecraft’
Fast Radio Bursts (FRBs) are high-energy radio emissions that only last for a few milliseconds. The extraordinary astrophysical phenomenon was first discovered in 2007, but since then there has been fewer than two dozen detected. The FRBs can only be detected by gigantic radio telescopes like the Arecibo Observatory in Puerto Rico and the Parkes Observatory in Australia. On Monday, a team of astronomers associated with Australia’s Molonglo Observatory Synthesis Telescope announced the discovery of three new Fast Radio Bursts (FRB 160317, 160410 and 160608) over an 180-day period.
Two of the three newly discovered FRBs were discovered relatively close to the galactic plane, but their “dispersion measures and redshifts suggest an extragalactic origin.” However, the exact point of origin of these transient radio pulses is yet to be determined.
“We spent 105 hours following FRB 160317, 43 hours on FRB 160410 and 35 hours on FRB 160608, and no repeat pulses were found from any of the FRB positions.” the researchers wrote in their paper titled “The first interferometric detections of Fast Radio Bursts,” which has been accepted in the Monthly Notices of the Royal Astronomical Society.

They also made a fascinating finding that answered a decade-old question about the seldom seen phenomena. Many scientists believed that FRBs did not come from a galaxy far, far away, but rather was interference from Earth that was tricking astronomers into thinking their were originating from lightyears away. However, after developing software to examine through the thousands of TBs of data collected by the Molonglo telescope, they found the three new FRBs and that they originated from out of our galaxy.
So what are causing these Fast Radio Bursts that seem to never repeat? Most theories about FRB’s is that they are generated by cosmic catastrophes where the source of the energy is destroyed such as a “star exploding in a supernova, or a neutron star collapsing into a black hole.”
However, there’s another theory that’s even more intriguing. Astrophysicists at Harvard University say that mysterious energy bursts could be from alien spacecraft! Avi Loeb from the Harvard-Smithsonian Center for Astrophysics, and Manasvi Lingam from Harvard University, say there is the prospect that FRBs come from the propulsion system from an alien spacecraft, possibly from lasers or microwaves.
“Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven’t identified a possible natural source with any confidence. An artificial origin is worth contemplating and checking,” Loeb said.
From the Futurist:
If FRBs are indeed the result of an alien propulsion system, here’s how it would work: Earth is rotating and orbiting, which means the alien star and galaxy are moving relative to us. That’s why we would only see a brief flash. The beam sweeps across the sky and only hits us for a moment. The repeated appearance of the FRB could be a clue to its alien, technological origin.
The authors of the study outlining this thinking know that it’s speculative. But it’s their job to speculate within scientific constraints, which they have done. As they say in the conclusion of their paper, “Although the possibility that FRBs are produced by extragalactic civilizations is more speculative than an astrophysical origin, quantifying the requirements necessary for an artificial origin serves, at the very least, the important purpose of enabling astronomers to rule it out with future data.”
Keep in mind, if these eniogmatic energy bursts are from a distant galaxy, it would have taken thousands of years for that FRB to reach Earth. And if they are indeed from alien spaceships, then they are incredibly more advanced than us. That means if they make it here we’re totally fucked.
