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: "A candidate sub-parsec binary black hole in the Seyfert galaxy NGC 7674", Kharb, Lal and Merritt 2017 https://arxiv.org/abs/1709.06258 You can further support us on Patreon at https://www.patreon.com/pbsspacetime Get your own Space Time tshirt at http://bit.ly/1QlzoBi Tweet at us! @pbsspacetime Facebook: facebook.com/pbsspacetime Email us! pbsspacetime \[at] gmail \[dot] com Comment on Reddit: http://www.reddit.com/r/pbsspacetime Help translate our videos! https://www.youtube.com/timedtext\cs\panel?tab=2&c=UC7\gcs09iThXybpVgjHZ\7g Previous Episode: Are the Fundamental Constants changing? https://www.youtube.com/watch?v=YJzoelANL\_Y&t=8s Related Episodes: How to Build a Black Hole https://www.youtube.com/watch?v=xx4562gesw0 Why Quasars are so Awesome https://www.youtube.com/watch?v=3TZEp\_n3eIc Links to Comments Response: Nevermind https://www.youtube.com/watch?v=YJzoelANL\_Y&lc=z223hpipuozhh1qbj04t1aokgn5pfpqlq0zgbnrilm5obk0h00410 Lutra Nereis https://www.youtube.com/watch?v=YJzoelANL\_Y&lc=z22cwtzjvv3ojx0ucacdp430ixcyhmpsu1ahlosnyedw03c010c Arnaldo Castro https://www.youtube.com/watch?v=YJzoelANL\_Y&lc=z22txnyo1lnwh1j03acdp430bunzm5m4x3xf5jwx0xxw03c010c 0xFFF1 https://www.youtube.com/watch?v=YJzoelANL\_Y&lc=z23sjnwjrwnljxe3macdp434i1lxdqjdsvf2ovd3r41w03c010c WispXLegend https://www.youtube.com/watch?v=YJzoelANL\_Y&lc=z22rivtz4oz2db4kmacdp431v2mactt0223icalvag1w03c010c Rubbergnome https://www.youtube.com/watch?v=YJzoelANL\_Y&lc=z22phdvhwsyehtjxe04t1aokg3gkri0vdluvsttfuju0bk0h00410 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.
