Harvard Scientists Theorize That Fast Radio Bursts Come From Alien Space Travel

Fast radio bursts (FRB) are perhaps the most mysterious phenomena we observe in the cosmos. Earlier this year, astronomers announced they had pinpointed an FRB for the first time in a dwarf galaxy that sits three billion light-years away. These intense blasts of radio waves last only 1 to 5 milliseconds, and they have perplexed astronomers since the first one was discovered in 2007.

The leading theories suggest that FRBs come from incredibly volatile cosmic events, such as material being ejected from supermassive black holes, the explosions of superluminous supernovae, or rotating magnetars that lash surrounding material with their immense magnetic fields. But researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) have proposed a much more enticing theory. What if FRBs aren’t natural phenomena at all, but rather come from a massive artificial structure used to power alien spacecraft?
