Abstract

Since this article was submitted there have been further exciting developments in the field of observational black hole physics:
– At this point LIGO has at least ten solid gravitational wave observations of compact object mergers https://www.ligo.org/news/index.php#O3resumes
– Upgraded LIGO, with 40% increase in sensitivity started runs on April 1

– In February, 2019, LIGO received funding for a $35 million upgrade, called “Advanced LIGO Plus”, due to be completed by 2024 https://www.ligo.caltech.edu/news/ligo20190214
– The international Event Horizon Telescope revealed an image of the event horizon of the supermassive black hole at the center of a galaxy (Messier 87) 55 million lightyears from Earth. https://eventhorizontelescope.org
