A search for links between two of the universe's most spectacular phenomena has come up empty—for now

Every so often, astronomers glimpse an intense flash of radio waves from space—a flash that lasts only instants but puts out as much energy in a millisecond as the sun does in a few years. The origin of these "fast radio ...
