What is a black hole?
A black hole is a region of space that has so much bundle knockout in it that there is no way for a close object to escape its gravitational pull.
If you threw the rock straight up in the air hard enough, you could make it escape the planets gloominess entirely. It would keep on rising forever. The speed with which you need to send away the rock in pasture that it just barely escapes the planets sombreness is called the escape velocity. As you would expect, the escape velocity depends on the mass of the planet: if the planet is extremely massive, then its gravity is actually strong, and the escape velocity is high. A lighter planet would agree a smaller escape velocity. The escape velocity overly depends on how far you are from the planets center: the closer you are, the higher(prenominal) the escape velocity. The Earths escape velocity is 11.2 kilometers per second (about 25,000 m.p.h.), while the Moons is solely 2.4 kilometers per second (about 5300 m.p.h.).
Now imagine an object with such(prenominal) an enormous dumbness of mass in such a small rung that its escape velocity was greater than the velocity of light. Then, since nothing mountain go faster than light, nothing can escape the objects gravitational field. Even a beam of light would be pulled guts by gravity and would be unable to escape.
A mass dousing so dense that even light would be trapped.
nearly immediately after Einstein positive general relativity, Karl Schwarzschild detect a mathematical solution to the equations of the theory that described such an object. It was only much later, with the work of such people as Oppenheimer, Volkoff, and Snyder in the 1930s, that people thought seriously about the hap that such objects might actually...
The black hole concept was developed by the German astronomer Karl Schwarzchild in 1916 on the behind of physicist Albert Einsteins theory of relativity.
