A Black Hole Formed By May Have Gone Rogue

A Lopsided Merger

Merger events between

 black holes can deliver a "kick" powerful enough to send a black hole spinning out of its galaxy.

Scientists discovered that

the black hole created in that collision and merger had been sent hurtling through space at 3 million mph

When two black holes

collide, they leave behind a more massive, remnant black hole.

When black holes orbit

 each other, they emit gravitational waves — essentially gravitational radiation

That carry away

 energy and angular momentum as they ripple through the fabric of space.

These emissions cause

 the orbit to shrink, leading to a collision and merger of the black holes.
