A mysterious burst of radio waves that have reached Earth has got scientists excited. Powerful repeating signals have come from beyond the Milky Way galaxy. Researchers from McGill University in the US have detected fast radio bursts (FRBs) from deep space that were not part of an explosive event and came in repeated waves. Silicon Republic reports: Until now, all discoveries of FRBs have been one-off events, with the most likely origin suggested by researchers being a major cataclysmic happening in space, like a star exploding into a supernova, or a neutron star collapsing into a black hole. FRBs are so hot right now In fact, FRBs were only recently used to confirm the cosmological model that there is indeed ‘missing matter’ out there in the universe that we simply can’t see. The same major cataclysmic events presumed to be responsible for FRBs have created the recently-discovered gravitational waves that are being heralded as one of the most important scientific discoveries for decades. However, in one region of space recently listened to, a series of FRBs are leaving researchers scratching their heads as, for the first time, there has been a detection of repeating short-duration bursts of radio waves from [...]
