Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

Black holes keep ‘burping up’ stars they destroyed years earlier, and astronomers don’t know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable ‘burping’ bouts. Half of all star-killing black holes may experience the same.

    I wonder if it could be caused by other celestial bodies captured in the black hole’s orbit. Some new mass approaches the accretion disk and the gravitational pull slingshots some of the disk’s matter out.

      For the forces required to “pull” the matter out, we would need another singularity, but even then, that wouldn’t show this.
