One of the more intriguing unsolved modern mysteries is the fast radio burst (FRB) phenomenon. Over the last several years, radio telescopes on Earth have been detecting more and more very brief, very powerful radio signals which originate from deep space. While astronomers have been able to locate the source of several of these signals, the exact mechanisms of their production remain a mystery. Of course, it has been speculated that they might be attempts at communication made by advanced alien races, or even that they might be a form of alien spacecraft propulsion for deep-space travel. Whatever these radio bursts happen to be, astronomers believe that similar signals might indeed be used for communication across vast distances of space. While we haven't determined that any of them might be a collect call from deep space, one astrophysicist has just published a study which sought to determine whether such signals could indeed encrypt information and if our squishy little human
