Black Hole and 100 Years old Theory

The Event Horizon Telescope Collaboration observed the biggest ever black hole at the center of M87.  The dark central shadow or black hole is in accordance with General Relativity, further demonstrating the power of this 100 year-old theory.  Astronomers from around the world held six major press conferences simultaneously in Belgium, Chile, Shanghai, Japan, Taipei and the United States. At the event, they revealed something no human has ever seen before: the first-ever photograph of a black hole. The picture comes from the Event Horizon Telescope (EHT), an international collaboration behind a planetary effort to snap a picture of a black hole. More than 200 scientists have participated in the project from 60 institutes in 20 countries.
