So what happens when two Super Massive Black Holes collide? We may be about to find out, because astronomers have spotted a pair of them in a close binary orbit for the very first time.

This episode of Space Time Journal Club discusses:

In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow. This paper was just published in Nature Astronomy by Preeti Kharb and Dharam Vir Lal from India’s National Center for Radio Astrophysics, and David Merritt from the Rochester Institute of Technology.
