Alien Theories Resurface as Cosmic Radio Bursts Traced to Massive Galaxies

A mysterious radio signal, FRB 20190203, detected by a Russian telescope from a galaxy 2.3 billion light-years away, has reignited speculation about extraterrestrial life. This Fast Radio Burst (FRB) is notable for its intense energy and low detection frequency, and unlike many FRBs, it has not repeated, adding to its mystery. While theories suggest natural origins like magnetars, the possibility of it being a technosignature from an advanced civilization remains. Further research is needed to understand this enigmatic signal.
