The mysterious celestial phenomena fast radio bursts (FRB) might be caused by advanced alien technology or alien space travel, according to a new theory proposed by Harvard researchers.
Scientists have catalogued less than two dozen FRBs, which can be described as superbright flashes, since the first one was captured in 2007. Many scientists believe that FRBs come from galaxies millions or billions of light-years away.
Avi Loeb, a theorist from the Harvard-Smithsonian Center for Astrophysics, said the artificial origin of the FRBs is worth contemplating and checking.
Proposing the theory, Loeb said, “We haven’t identified a possible natural source [for FRBs] with any confidence. An artificial origin is worth contemplating and checking. Specifically, these bursts might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies.”
The powerful FRBs are one of the most enigmatic phenomena in the field of astronomy and have intrigued researchers for years.
FRBs are pulses of powerful radio energy that originate from some unknown cosmic location. These pulses last for just a few milliseconds before disappearing forever. However, such pulses can emit as much energy in a millisecond as our Sun does in roughly 10,000 years.
