When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed -- or "spaghettified" -- as the black hole swallows it.
Astrophysicists from Johns Hopkins University argue that FRBs provide a direct way of detecting black holes of a specific mass, which are the suspect of dark matter.
An unusual source of intense radiation is likely powered by a "direct-collapse black hole," a type of object predicted by theorists more than a decade ago.
