The international Event Horizon Telescope (EHT) project aims to observe the supermassive black holes at the centers of galaxies, such as Sagittarius A* at the center of the Milky Way and the more distant M87* in the galaxy M87. Using Very-Long-Baseline Interferometry, the project can observe the shadows of the supermassive black holes that block the bright light emitted by their accretion disks. The EHT ties together radio telescopes ranging across the western hemisphere of Earth to create, in effect, a planet-size telescope. The EHT will determine the size of the shadow, which can be compared to the predictions of general relativity and modified gravity theories. The EHT will also observe the physics of the accretion disks surrounding supermassive black holes. These observations can potentially determine whether a black hole event horizon exists.
