Professional brainiac Prof. Stephen Hawking came up with a good idea a while back, using light from lasers to propel tiny spacecrafts at the speed of light across the cosmos and other scientists have now come to think that aliens may be doing exactly that which would explain the strange flashes they keep seeing.
Scientists have been pondering just what the weird flashes detected in distant galaxies could be and after dismissing it being a natural phenomenon, are now considering they could be powerful transmitters sending ships on interstellar voyages.
Professor Avi Loeb, from the Harvard-Smithsonian Centre for Astrophysics, said: 'Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence. An artificial origin is worth contemplating and checking'.
They estimate that the energy levels responsible for the bursts would be enough to push a payload weighing a million tons and large enough to carry living passengers across intergalactic distances.
Exciting, or possibly dangerous, possibilities that other civilisations could be roaming the Universe and civilisations that are technologically so advanced that they have built and operate the thing that we, or Stephen Hawking anyway, has only just thought of.
