John Archibald Wheeler in 1967 which gave the name "black hole" that became popular in the world have actually become a favorite topic of science fiction writers. Black hole is a concentration of mass great enough to produce a very large gravitational force .
Black hole is created when an object can not withstand the power of the force of its own gravity. The masses of black holes continue to grow in a way to capture all the material nearby. All material can not escape the bondage of black holes if passed too close. So the object that can not keep a safe distance from the black hole will be exploited. The black hole also can increase its mass in a way collided with another black hole to become a greater black holes.
Earth is 93 million miles from the sun, or about 8 minutes the speed of light, but do we know the distance of the earth with a black hole. The distance between the earth is 30,000 years with a black light speed. One year of the earth around the sun, the earth rotates during the 29.5 days, but the sun around the central black hole for 220 million years.
