Abstract

The Event Horizon Telescope, global array of millimetre telescopes, has now enabled studies of nearby supermassive black holes on sub-horizon length scales. This unprecedented access opens a window onto not only the high-energy astrophysics of black hole accretion and jet formation, but also the nature of gravity in the heretofore unexplored strongly non-linear regime near the black hole horizon. I will summarize the state of the Event Horizon Telescope, what results obtained over the past 7 years, and how a revolution in capability will produce precision tests of strong gravity over the next 2-3 years.
