There, a plasma of several billion degrees Celsius is swirling around the black hole at over a 3,600,000 km/h. This system is simulated on a supercomputer. Analyzing the simulation we can create an image of what the black hole should look like as seen from Earth. With the global EHT collaboration we were able to combine telescopes all around the world to create a single, Earth sized telescope, which can then observe the actual black hole. After the observation in April 2017 it took hundreds of scientists two years to create the final image presented in this video. This observational image can then be compared to the simulation of the black hole, and with this we can once again test Einsteins Theory of Relativity against reality. The galaxy M87 is 55 million light years away or 52x10²⁰ km Its central black hole has a mass of 7.22 billion solar masses, or 1.4356x10³⁷ kg or 3.1651x10³⁷ lb Link to our homepage: https://relastro.uni-frankfurt.de/ Link to our gallery: https://relastro.uni-frankfurt.de/gallery/ Link to the EHT website: https://eventhorizontelescope.org/ Link to the Black Hole Cam Website: https://blackholecam.org/
