How did einstein know about black holes
WebDetails of the structure of a black hole are calculated from Albert Einstein’s general theory of relativity.The singularity constitutes the centre of a black hole and is hidden by the object’s “surface,” the event horizon.Inside the event horizon the escape velocity (i.e., the velocity required for matter to escape from the gravitational field of a cosmic object) … WebHá 1 dia · The iconic image of the supermassive black hole at the center of M87—sometimes referred to as the "fuzzy, orange donut"—has gotten its first official makeover with the help of machine learning.
