Humanity might have received a signal from aliens that it isn’t checking, says Harvard professor

Scientists might have found proof of alien life but misunderstood it, according to one Harvard professor. Strange radio waves that come down to Earth might actually be leakage from a huge light-powered ship deep in space.

Fast radio bursts, long thought to be perhaps the most mysterious message in the universe, might actually be evidence of advanced alien technology, according to Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. But researchers might not be doing enough to check whether the source of them is what Professor Loeb speculates – 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,” said theorist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. “An artificial origin is worth contemplating and checking.”…
