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.
That’s what the current understanding of physics says. But given that there are singularities that come out of the math, all that really means is we don’t actually know what happens inside a black hole.
