Could fast radio bursts be powering alien probes
Boston MA (SPX) Mar 13, 2017
The search for extraterrestrial intelligence has looked for many different signs of alien life, from radio broadcasts to laser flashes, without success. However, newly published research suggests that mysterious phenomena called fast radio bursts could be evidence of advanced alien technology. Specifically, these bursts might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies. "Fast radio bursts are exceedingly bright given their short duration and origin at ... read more
