It would also appear that such behavior around supermassive black holes can cause cosmic "traffic jams," and these these jams could actually be integral in slowing down the orbits of stellar-mass black holes. And, no longer zipping around, the affected black holes can be forced to collide, merge and create a larger daughter black hole.

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

Supermassive black holes are giant voids in the heart of all large galaxies. They swirl around disks of matter, stars and their systems, and interestingly, other black holes, including the smaller, stellar mass ones.

And you believed that rush hour was the worst thing ever? As per the recent research, many cosmic intersections have traffic lights that have failed, making black hole collisions
