Extremely fast extragalactic bursts of polarized radio energy known as FRBs (fast radio bursts) lacked a widely accepted explanation. Falcke and Rezzolla proposed if a neutron star were spinning fast enough its interior would collapse into a black hole and its outer magnetic field, cut off from its source, would be instantly converted to radio energy.
FRBs could be beacons from civilizations in distant galaxies. If so, the alien transmitters would need to be as big as planets. But how could there be so many of them, why don’t they use single frequencies, and why do only a few repeat?
The power of a name
Blitzars are still hypothetical but with a name like blitzars it may be hard to give it up. If fact doesn’t conform to theory a new explanation could reuse the name.
