Two Harvard University scientists are suggesting that mysterious fast radio bursts, detected in faraway galaxies, may be evidence of aliens traveling through the cosmos.

FRBs are extremely bright flashes of radio waves that last for only a thousandth of a second and are detected by earthbound telescopes. Since the first one was observed 10 years ago, 17 have actually been reported, although scientists think there are thousands of them a day.

At first, Abraham “Avi” Loeb said, he took a conservative approach to explaining them.

“It looked like the simplest explanation would be flares from stars in the Milky Way galaxy,” said Loeb, a theoretical astrophysicist and chair of Harvard’s astronomy department.

But then “one of the FRBs was localized to reside in a small galaxy at a distance of about a billion light-years away,” Loeb told The Huffington Post. (One light-year is about 6 trillion miles.)
