Do aliens exist?
Fast radio bursts (FRB), which have perplexed scientists since they were discovered in 2007, could be evidence of advanced alien technology, according to Avi Loeb of the Harvard-Smithsonian Centre for Astrophysics. Researchers, however, remain far from establishing whether the source of these “messages” is what Loeb speculates it is – leakage from planet-sized transmitters that are powering interstellar probes in distant galaxies.
“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,” Loeb has said. “An artificial origin is worth contemplating and checking.”
