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 remember when I used to believe that nothing escaped a black hole past the event horizon.

    I mean, nothing does, so why did you change your beliefs?

        Hawking radiation isn’t something leaving the event horizon, it’s created outside. Nothing that is inside can leave.
