Astronomers know for years that Fast radio bursts (FRBs) come from distant galaxies but their origin still remains a mystery. However, a new theory might have provided an answer to the question.
FRBs are pulses of radio energy or superbright flashes originating from some unknown cosmic location and last only a few milliseconds before disappearing forever. They can emit as much energy in a millisecond as our Sun does in nearly 10,000 years.
Now, a team of researchers from the Harvard-Smithsonian Center for Astrophysics has suggested that the FRBs might have come from planet-sized transmitters sailing aliens.
Theorist Avi Loeb said in a statement that the artificial origin of the FRBs is worth considering and checking.
The researchers wrote in the study, “Our analysis show that beams used for powering large light sails could yield parameters that are consistent with FRBs. Coincidences' lend some credence to the possibility that FRBs might be artificial in origin."
Since the first FRB was detected in 2007, astronomers have catalogued nearly 20 FRBs. They estimated that the pulses came from galaxies billions of light-years away.
The new theory linking FRBs to advanced extraterrestrial technology or sailing aliens appeared in a recent edition of the Astrophysical Journal Letters.
