Sometimes our local 5 billion year old star acts up and wants to have some fun. So he has a play date with tripple B.
Big Black Ball is a menace! Always starting trubble.
When tripple B gets too close, he just can't stop eating! Tripple B sometimes shoots jets of energy at 2/3 the speed of light when eating. When Tripple B eats, he burps! He has no manors! These jets sometimes rip threw dust clouds in space, and actually are good for star formation.
So in many ways, as long as you not near A Black Hole, they are quite good for otherwise boring galaxies.
