- Statement 1 is correct: A black hole is indeed a region of spacetime where gravity is so strong that nothing, not even light, can escape. This boundary is called the event horizon. - Statement 2 is correct: The first direct visual evidence and image of a black hole was captured by the Event Horizon Telescope (EHT) collaboration, released in April 2019, showing the supermassive black hole at the center of the galaxy M87. - Statement 3 is incorrect: The idea of a body massive enough to trap light was first speculated upon by John Michell in 1783 and Pierre-Simon Laplace in 1796 based on Newtonian mechanics. The modern concept of a black hole is based on Albert Einstein's theory of General Relativity (1915), and the first solution describing a black hole was found by Karl Schwarzschild in
