STRANGE radio bursts are bombarding our skies. We don’t know where they’re coming from. But some scientists have just suggested it could be the ‘exhaust’ of alien space probes.
Fast radio bursts are mysterious flashes from deep space that last just a few milliseconds.
They were first seen in 2007. Since then, about a dozen have been detected by the world’s larger radio telescopes, such as the Parkes Observatory in New South Wales. Scientists have been scratching their heads as to where they could possibly come from ever since.
A question without an easy answer? Therefore aliens.
Alien megastructures, anyone?
“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,” says Harvard-Smithsonian Center for Astrophysics theorist Avi Loeb in a statement.
“An artificial origin is worth contemplating and checking.”
