What could it be?

“My best guess is that

FRBs are produced by compact objects, and that they are very rare in nature. If they were common we would have already detected most of them from the galactic disc.” Jorge Zuluaga, University of Antioquia

“They will probably turn out to be ‘normal’ as far as stuff in astronomy goes. Probably our best guess at the moment is that FRBs are somehow made by neutron stars, but unlike anything we’ve seen in the Milky Way.” Vikram Ravi, Caltech

“In the time it takes you to drink a cup of coffee, hundreds of

FRBs may have gone off somewhere in the universe. If we can study even a fraction of those well enough, we should be able to unravel their origin.” Avi Loeb, Harvard University
