Given the bizarre character of black holes, it was long questioned whether such objects could actually exist in nature or whether they were merely pathological solutions to Einstein's equations. Einstein himself wrongly thought black holes would not form, because he held that the angular momentum of collapsing particles would stabilize their motion at some radius. This led the general relat… WebIn 2024 the Event Horizon Telescope obtained an image of the supermassive black hole at the centre of the M87 galaxy.
