> Curiously, because the luminosity of a typical quasar is not dissimilar to the peak luminosity of an FRB, we cannot yet completely discount the involvement of supermassive black holes. But Marcote and colleagues’ results argue against that possibility, and the timescales for quasar variability are more likely to be days to months than milliseconds.
I agree. As a child I thought these would be extremely rare. In my naive little kid brain I guess I figured there must be only a handful of them known to exist, and I had endless ideas about how such a rare and unique celestial entity must have alien origins. Haha.
