Mystery flashes may be aliens at work, say scientistsLEONHARD FOEGER "Aliens there are, maybe"Hold on to your lightsabers and brace yourself for hyperspace. A team from Harvard University suspects mysterious energy flashes detected in galaxies far, far away may be caused by a species of super-advanced aliens firing up their interstellar spacecraft. FRBs are intense radio pulses that last no more than a millisecond that emanate from remote galaxies billions of light years away. Or as Yoda might say: "Aliens there are, maybe". They say the FRBs could be evidence of aliens hard at work and that the bursts may be leaked energy from unimaginably powerful transmitters capable of sending giant light sail ships on voyages between stars.
