Fast radio bursts(FRBs),pulses of brief but extremely bright radio waves blasting from the depth of the cosmos,particularly those repeatedly erupting,have been fascinating astronomers and,astronomical amateurs as well,since their first discovery in 2007.What are they?What,or WHO,are behind these mysterious signals?Could it be a desperate telegram sent by an alien civilization seeking cosmic counterparts smart enough to decipher their message?Unfortunately,such bursts endure only milliseconds and hence are far too brief to allow closer astronomical observation and examination.About their origins,there exist even more theories than observed FRBs,just as a joke goes among astronomers to describe the smorgasbord of models attempting to explain their birth and propagation.
