Black Holes A black hole is the velocity necessary to take one away from one’s own gravitational force. For example, the escape velocity of earth is equal to 11 km/s. anything that wants to escape earth's gravitational force or pull must go at least 11 km/s, no matter what the thing is . The escape velocity of an object depends on how compact it is; that is, the ratio of its mass to radius. A

Black Holes
Black Holes Since their theoretical existence was first proposed in 1783 by English geologist John Michell, black holes have remained one of astronomy’s greatest mysteries. In his paper to the Royal Society of England, Michell explained that a star approximately 500 times greater in diameter than our sun and of the same density would have an escape velocity (the speed at which an object must travel in order to break free from a body’s gravitational

Black Holes
A black hole is an object with a concentration of mass great enough that the force of gravity prevents anything from escaping from it except through quantum tunneling behavior. The gravitational field is so strong that the escape velocity near it exceeds the speed of light. This implies that nothing, not even light, can escape its gravity, hence the word "black." The term "black hole" is widespread, even though it does not refer to a
